A few hours later, Nao comes out to the lobby in tears due to her lack of a game plan. Akiyama is seen to be calm and observant to his surroundings. He tells her that she should start getting to know her enemies. With this, he uses her to gather information.

The first thing was to test if that plan would work by seeing the LGT reaction by breaking a card. Therefore, Akiyama broke Nao’s card and told them. They immediately gave him a replica, so the plan would work.

At the end of the revival round, Akiyama comments about how the LGT office planted a lot of traps to steal money from the players, and that their system, that seemed profitless, wasn’t at all.

Aki planned from the start to be the last person standing, freeing all the losers and becoming a slave of the LGT office.

Nao, having communicated with Akiyama about her plans to win the game, comes up with 4 strategies in order to win. He quickly rejects each one, positing that the key of the game is to establish trust, without that, no one would go into action. With this, he formulates his own plan.

When Baldy selfishly said that he didn’t want to become a Gaya, Akiyama figured that this current time was the best time to eliminate him. Baldy would probably already be planning to betray Akiyama’s team if he argued. This is the current configuration in which chairs are rotated:
Source: Liar Game, Musical Chairs Arc
His first move in this plan was to manipulate Harimoto into giving his cards using the religion argument. He wanted him to put his cards in a lot, but he didn’t plan to save Kawai with that lot, his objective was different. Harimoto since the start didn’t want to give his cards, because this would make his profit lower, so he was desperately trying to find an excuse for his servants to not save the other players. Akiyama knew this, so he told Baldy to bid 2 more coins in Harimoto’s lot, to avoid the risk of someone trying to outbid him by one coin. But this wasn’t the main objective, he wanted to give Harimoto the argument he wanted: “Baldy didn’t trust us from the start, if he did he wouldn’t bid 2 more coins and would bid the amount we agreed in the start. Since you guys don’t trust us, we won’t trust you neither” (summarized) Harimoto telling every player that he won’t trust them was the first goal, with this he was able to make every player not try to ally with Harimoto in the future, since he himself stated that he won’t trust them. He also wanted to make Harimoto bid 301 coins in his cards (he couldn’t bid less because Kawai had 300 coins, so he needed to guarantee that he wouldn’t outbid him). Harimoto indeed sold without wanting his 5 extra cards, but he could take another 5 cards by buying Akiyama’s 5 extra cards (the agreement was that both of them would sell their cards to players without cards to save them), so he used the money that Baldy gave his group by buying his cards + 68 coins to guarantee that Kawai wouldn’t outbid him (Kawai had 300 coins, Baldy gave Harimoto 233 coins. 233 + 68 = 301 > 300). Akiyama’s true objective with this was to manipulate Harimoto to give him 68 coins of his, all Baldy’s money and to say that he won’t trust any player.

Afterwards, the players started to try to improve their hands by exchanging cards with other players. This is a risk, because Harimoto and Kimura could buy their cards and make them become a pig (Pig = player with 4 cards or less = loser) but since Harimoto didn’t know how much money they would bid, they would be fine, because the chances of him getting right by just a little amount of coins are very small. Akiyama ordered Kawai to spy on the players and see how many coins they planned to bid. He then told Kawai to make a contract with Kimura: you save me at the end of the game in exchange for this information about the coins they were going to bid. She didn’t trust him in the start, but since the risk of this deal looked like zero she decided to accept it. She out bidded the first player by 10 coins, Kawai really didn’t lie, the player bidded the exact amount he told them, then the next again by 10 coins, Kawai didn’t lie again, the next ones by 5 and 1 coins, no lies from Kawai. Now, there are a total of 6 pigs in the game (Kawai + Nao + 4 players Kimura outbidded) and Harimoto was already in first place, so 600 million yen from each of the players was going directly to him. In the last round, with all the players in pure despair, Akiyama told them the plan:
Source: Liar Game, Bid Poker Arc
In the 17th player lot, Akiyama placed a bid. His objective with this was to make a scenario where only already formed groups would win, in this case, there was 3 groups of 3 in total, when Akiyama bid on the guy, this would make him unable to be bidded, because you can’t bid on people that are already in a group. He then tells everyone that he plans to make Kanzaki Nao one of the winners, and that he was going to buy the 18th lot too, making only her group formed, therefore they would win automatically, hence the lack of competitions. In turn, the other 15 players immediately lose.

“If you keep doubting people and searching what’s inside them, sooner or later you’re bound to understand something about them. And when you do, you’ll be able to entrust something to them. This is what it means to trust and believe. I… forsook his words for a long period of time. But you know… meeting the honest to a fault Kanzaki Nao made me remember them. When she got caught up in this game and was agonizing over it, I said to her that she should doubt people because it would be the same as her attempting to get to know them. She followed my advice with blatant honesty, trying to establish communication with the players she met and doing her damndest to get a glimpse into their hearts as long as the time permitted. You’re right about all the people here being good-for-nothings. They’re weak, selfish, impatient and generally full of shit. But, through her communication with them, their hearts began to understand. Yokoya. This tie is, by no means, dumb luck. And neither it’s the result of my plan being all that great. This is the one move of trust that was only possible because of Kanzaki’s efforts to doubt people around her and understand them in their entirety, and this is the victory of Kanzaki who continued believing in people despite everything she’d been through.”

Akiyama found Nao at a mental low point, on the verge of tears, but he managed to calm her down and use her as he had intended, influencing her to have a good composure, Acting Skills etc… He was sure of himself and his plan to make Nao feel confident, and he also used his words to make her lie and deceive to get out of trouble. Akiyama succeeded in managing Nao's emotions, gradually developing her to overcome her weaknesses, such as her excessive kindness, and encouraging her to adapt to the game.

The team begins boycotting the elections. He understood that Yokoya and Harimoto only became allies because Akiyama’s team was a bigger threat. So if Akiyama’s group stopped voting, that means that there isn’t any greater evil to fight, and causes Harimoto and Yokoya’s alliance to break. Harimoto would most likely try to figure out a way to defeat Yokoya and realize his tactic. Not only that, but they also gained 20 minutes of time in order to search for chairs. Akiyama, in one move, indirectly caused Harimoto and Yokoya to fight each other, as well as protecting their own team from attack.

Akiyama persuades Akagi, Shibayama and Hasegawa. But the way he persuaded Hasegawa was different. He decided to reveal the fact that all three of them were collaborating. He posits that the Northern Team was racked with paranoia, and by acknowledging that there were more people on your side, there will be a sense of unity. You may think that revealing there were other traitors would lead to the bluff being exposed, but by the time one person actually gets the money through, the situation would have inverted, and in order to escape the sinking ship that is the Northern Team, then they would have to collaborate anyway.

As usual, I will explain the situation of the game before talking about the strategy. Yokoya, having stolen 3 players to his side in order to gain the advantage, has left Akiyama’s group with 4 people. The other 2 players, (Butch and Slick) have exiled themselves and abstained from further contact now that they’re at NORMAL4. Yokoya manipulated Nao into contacting Akagi, so he is NORMAL now. But the issue is, neither Nao nor Four-Eyes can reach NORMAL4 before the round ends.

Akiyama told Fujisawa that he was going to call the police because he stole Nao’s money. The teacher interrupted him saying that it was just a game and that he didn’t commit any crime. Akiyama manipulated him to say that he considered it a game, not a scheme, so he really intended to trick Kanzaki.

Akiyama said out loud that all he needed to do was to fill 3 sequences in a roll, when the other guys were nearby (by placing the bullets next to each other once the gun shoots you know that at least the next 2 chambers will have a bullet if the opposite team is using the same strategy) . They tested that reasoning and applied it in the gun, causing both teams to apply 3 bullets in concession which controlled the center of gravity.

Before the round starts, Akiyama gives each player a piece of paper and asks them to write two names of people they didn’t want him to represent in the game (he will shoulder their debt.) He wanted to save the person who caused the least problems among all of them.

Acknowledging the most rational win-condition, he formulates a plan. He colluded with No. 15, allowing him to gather information about Fukunaga’s possible strategy. This is all a day before the final showdown, by the way. He uses No.15 to speak to the other 2 players, starting a negotiation. Their strategy will have No.15 winning, voting YES, while the other 2 vote NO. He will then move into the next round, not paying the 50% fee. Then all the money will be split amongst them, allegedly. Fukunaga, having used an alias on all their contracts, is not obligated to pay back every team member, but for the other 2, they must take full responsibility as a winner and pay them all back. The numbers goes like this:
Source: Liar Game, Minority Rule Arc
Akiyama’s plan was to make Nao tell every player privately that there was a secondary revival round where the loser with the most votes is the winner. The current winner of this round just has 19, thus Nao, who already has 10, just needs 10 more to be able to win the secondary revival round. Adding to that, she will give them 70 million, putting them on more with Fukunaga, as well as having Nao’s full obedience in the 3rd game. With all these benefits, considering the fact that Fukunaga already gave Nao 10 votes and their strategy didn’t malfunction because of that, no one denied to give Nao their votes. Of course, she didn’t tell them that they weren’t the only ones she was dealing with. Now, Nao owns 80 votes (10 she already had + 70 purchase in this round) and there are 3 players in the last place that won’t be able to make it. Akiyama then shows up and states he’ll be selling the final 30 votes to the highest bidder. Why 30? Well, the quote to winning the game is 50 votes. This is because, for each round, you can cast 5 votes using the M ticket, and since there are 10 rounds, each person has 50 votes in total. With 9 people, the pool becomes 450 votes in total. If someone has 50 votes, then every other player would need 51 votes in order to secure the win. But adding that up, (51x8+50=458) exceeds the total pool.

Akiyama posits that most of these players are selfish, only requiring personal merits to join the alliance. Using his negotiation and narrative-creation skills, he employs Young Jump as his proxy in order to control Gaya votes. He also takes advantage of the fact that Gayas have no chairs, nor are they teamed with any particular factions, so they have no idea whose chairs are getting eliminated each election. He uses Young Jump to spread the information that the Akiyama team has abstained from doing voting as a defense mechanism, and that they had no intention of winning in the first place, those being the reason why they started to boycott the elections. This means, someone from Yokoya and Harimoto’s group would win, and all attention should be focused on a strategy in order to seize as many medals as possible, so that whoever the winner is, they’ll make profit. Young Jump was able to persuade the Gaya by showing how all the coins they had and realizing that the sum of them gave the original players almost zero profit, this proved that they had only garbage coins, so they should ally with each other to manipulate the final winner to be whoever gave them the most medals. For example, if Yokoya gave 2 medals of his to all the Gaya and Harimoto gave only one, although you can’t divide 2 medals with everyone, the alliance would agree to make him win that round.

Akiyama knew exactly what Kikuchi was thinking in the last round, he was worrying about Akiyama shuffling, just by seeing him. He also states that luck is now on his side, making Kikuchi stop worrying about a possible strategy that he used to win the ninth round.

Akiyama realized that in the Liar Game system, the LGT profit comes from the winners who retire (half of the profit of the winners who retire goes to the LGT) and from the revival round. Furthermore, the money awarded to the winner is Zero-Sum, meaning the other players’ losses are distributed to the winner, so in essence no money is being lost from the initial pool in the game. If we had a player, who wins all the games and pays back the entire debt of the losers every round, and takes all the debts from the revival rounds, LGT would only have one person with a tremendous debt and a bunch of losers with no debt at all. It doesn’t matter how good LGT is at collecting debts, they can’t take billions from one person. LGT would go bankrupt.

Akiyama used a non-performing loan (business term) to formulate that strategy.

Mikamoto, now having “Harimoto’s Tablet” (It’s actually Kimura’s original tablet) prevents Kimura from being able to bid under her own name. This means Nao’s strategy for everyone to have an allocated bid would go wrong, since Kimura’s bid would be taken by Harimoto’s name.

Akiyama always knew his strategy was not a 100% win. If 2 teams were made with the same purpose, then the game would be locked in stalemate, likewise, if 3 teams were made, that would mean one person in all 3 teams would exist, likely Mr. X, which means they would be locked in stalemate.

With this, the strategy was made, but No.15 knew Fukunaga would not like these terms, due to her greed. This in turn manipulates her into forcing a draw, in which the real plan comes into place. No.15 takes the two votes Fukunaga and No.11 had, and places them in to make sure a 2:2 equal ratio is made. He brings over the ballots into the box and… instead of 2 NO’s and 2 YES’s, there are 3 YES’s. No.15 intentionally voted for YES in order to force in Akiyama the minority. Although the whole fake strategy was mostly No.15’s doing I assume, I’m sure Akiyama had some play in the accordance, as he wouldn’t let him mess things up. As he wins the Minority Rule game, he manipulates Fukunaga to give the 100M yen check back by threatening to call the cops. After all is said and done, he collects 2.2M, paying back No.15 and his team, as well as recovering the money for everyone else. He plans on playing the next game as well, as it intrigues him.

Northern slammed, so inspecting the exact amount doesn’t give you more money, it just protects the money you already have. The real objective of the game is to smuggle money and lose, the numbers in the outside account just represents the winner, not the one who wins more money.

This move forced LGT to cancel the Liar Game, since the money to pay their food and water for years would be greater than the money to pay their debts. Technically, it was LGT's fault that they ended up indebted, because they weren't able to hold the tournament until the end and had to cancel the last round. Therefore, the players who could’ve won and paid their debts wouldn’t be able to do so anymore, so LGT had to pay all their current debts. And even if Yokoya were to have deployed a traitor which would let their own team lose, it was still more probable for Akiyama’s favor. His solution allowed for a riot upon the administration which caused pain to so many, while also potentially losing nothing, whereas 2 players on the losing end of the final 2 would be left with debt (the general and the boss’s debts would be paid for cooperation.) This is also in association with Kanzaki Nao’s ability to unify and trust people, guiding their intentions against a common enemy rather than themselves. That’s what “trusting it to the humans” means. Rather than Yokoya’s somewhat Hobbesian beliefs that humanity inherently acts for selfish and deceptive reasons. Akiyama saved everyone and forced yet another powerful organization to demolition.

Akiyama observed that Kikuchi exchanged 4 cards, but this is an illogical move, since you always get 5 cards and there are only 17, in every hand you’ll get at least one pair, meaning that Kikuchi discarded a pair, which made his hand worse. This shows that he is planning something.
Source: Liar Game, Revival Round II Arc
When the simulation round ended, Akiyama was able to understand how the game works. He explains to Nao that winning as a dealer is better than winning as a participant, because if you trick the participant to miss the right number, the dealer takes everything, while if you guess right as a participant, the dealer would most likely also get right, meaning that you would have to divide your profit with the dealer.

In the bidding, Akiyama needed the players to bid less than 100 coins to give less money to the LGT office. Therefore, he told everybody that the person who gets 2 lots wouldn’t lose no matter what. This made them try to get two lots in the cheapest way possible, by dividing the 150 they had in two bids they planned to do, hence they needed to bid less in the first bid and more in the second, they would bid 75 maximum in the first, manipulating them to bid less than 100 coins in the next bid.
Source: Liar Game, Bid Poker Arc
When the game started, Akiyama already realized that it would be almost impossible to save every player, because if the average debt of each player is just 150 million along with the losing debt of 300 million, he would already need 2 billion just to save them. Which is a giant amount, even if they win.

Later on, the Science Professor had claimed that a file containing the questions to the Environmental Science Entrance Exam had been found tampered with and possibly had been captured on photo in order to cheat. The file itself is located in a locked drawer, in the 17th slot to be exact. The lock code was always set as 0000 when used by the professor. Except for this time, where the file was found to be in the 15th slot, left with the code 3105. The only two people who had the code were the professor and his wife. The professor’s hypothesis was that the code had been found out using constant trial and error, by entering his office while he was lecturing. All the evidence seemed to stack up against Akiyma’s highschool friend. But Akiyama noticed a contradiction, which was the fact that each time the thief had supposedly attempted to open the drawer, the dial had been set back to 0000, until the last time. This indicates that the shift in files occurred only when the drawer had been successfully broken into, the span of 1 day. But even that in itself would be contradictory, as if a thief attempted to crack a code in one day, noticing that the dial had been at 0000 before he attempted to change it, the natural thought process would be to recognize that the professor always turned it that way. This means that it’s totally illogical to leave it otherwise, even if the thief did manage to crack the code in one day. Furthermore, Aki’s friend noticed a woman leaving the office room, which means that woman may have been the professor’s wife. With this theory, Akiyama accurately finds out that the wife simply was trying to find a file (as she’s working as a nurse in the same university), and set the dial to 3108 because the 3 apparently means San, 10 means Too, and 8 means Go, the voiced consonant of Ko. Putting that together spells the name, “Satoko”, which is the professor’s wife’s name.

Hence Kikuchi already had two aces, he would only exchange two cards, giving him two J and leaving a four of a kind of Q’s to Akiyama.

Then after that, Akiyama revealed that the hidden money was a bluff, and there was still 1.9B that had to be deposited. Hasegawa said that Yokoya probably wouldn’t allow anyone from the three supposed traitors to go again. But Akiyama has a solution to that. He had tested what would happen if the card was broken, he found out that the LGT employees simply give you another one, he used that to break Yokoya’s ingenious system. Akiyama had investigated this well in advance, he had managed to imagine how useful this information on the maps could be to him, and from the moment Akiyama predicted that Yokoya was going to prevent one of the potential spies from going to smuggle, Akiyama was able to filter through all the information at his disposal to find a way of countering Yokoya's strategic response, all the while being dozens of moves ahead (just in this area, not all contraband), showing that he was putting all the chances on his side and preparing for every possibility. To avoid traitors, Yokoya created a system where he would give each player a different person’s card when they smuggle. As well as returning their card again after they smuggled it. If they didn’t return their card, Yokoya would burn their original card making their profit zero, since they cannot win any more money if their card no longer exists. To counter this, Akiyama took the magnet of the speaker in the Customs Office that the staff was using to communicate with the players and rubbed it in the card that Hasegawa was carrying, making the chip data malfunction and the card break. The staff gave another card to Hasegawa, which he gave to Akiyama and kept the broken one. There wasn’t a single scratch in the card broken by the magnet, hence Yokoya didn’t even suspect that Akiyama was in possession of one of the Northern cards. Another 1.9B secured, the tides of the game have severely shifted. Since this event was entirely concealed, Yokoya believed that there was one more step to Akiyama’s plan, when in reality, all the money was already seized.

Akiyama observes that the shortest ways to get to the rewarded chairs were marked in the map, so to avoid someone finding them in the way to the chairs, Harimoto probably ordered his group to hide the chairs in places that aren’t marked in the map.

When the second round of Bid poker ended, Akiyama was declared as the winner by bidding 3 coins. Akiyama observed when Baldy moved his tablet that the way Kimura arranged the circle, she would get in a blind spot if he claimed some attention, so she would be able to bid without anyone looking if a distraction was created. Harimoto moving also created that spot, therefore when Harimoto started dancing Akiyama bidded 3 coins, because he predicted that Kimura would use the distraction and bid 2 coins. He also deduced that Kimura had Harimoto’s tablet when he saw the results of the first round appear.

Akiyama told all of this to both groups, making them both only use one LP every round, ending it with both of them having only one LP and not being able to do any actions, creating a stalemate. This trap worked because the only one who wouldn’t care about the rich player would be Yokoya, who already has a lot of money and wouldn’t care if another player survived that round even if he lost, unlike the other players, who wanted to know who that person was. Also because Nao always presents strategies to save every player in the start of the rounds, Yokoya didn’t find it suspicious when she presented another and didn’t think much of it. Akiyama predicts all of Yokoya’s moves from their start, he predicts that he would make himself lose, predicts his deal with the other two teams and predicts that he wouldn’t be able to win in these conditions. All in order to create perfect stasis in the game which would force the LGT staff in an infinitely long waiting game.

The real purpose of the Contraband Game was to lose. If you were able to gain money by inspecting, this money will be added to your account and removed from your own ATM. Since there’s a rule stating that all the money in each team’s ATM will be divided amongst each other, this seems a bit illogical, right? Well, if you think about it differently, inspecting’s main purpose isn’t for the endgame revenue, but to stop a smuggling attempt. In the event of a successful smuggling, money from your own team’s ATM is taken to the other team’s outer-account, nullifying it.

Akiyama claims he used to work a job where he fixes circuit boards, and that he’s built things very similar to that watch. He goes on to explain that the circuit boards are used in medical facilities, somewhat like an emergency alert system mechanism which allows unconscious patients to convey their condition to their nurse.

Akiyama and Nao firstly persuaded Kaneko, one of the earners, to work with him. He asked her to bid on the other two wealthiest players in her group, making them the richest group. The other players also began creating their groups to be able to bid more on Akiyama. (context: Akiyama was the last person to bid, therefore everybody was trying to gain the biggest amount of money possible to win him). But at this point, Nao had already been bidded on by Yokoya, so if either player won the other would lose. Nao’s team gets one last player and fills the 4-player quota.

Fourth, they all should do the most logical moves, these being only attacking and only defending. Looking at the graph to the right, (which Akiyama created himself btw), if a team decides to do defense, then there will be at worst a loss of 1 point in the case of an enemy doing no action. But the way to prevent that would be to throw in multiple offenses from time to time in order to scare the enemy into not taking their chances with a risky no action.

“People should be doubted” Akiyama’s philosophy of life: “doubting people is simply a part of trying to know them. Trust, that act is without a doubt a very noble one… but you know what many people do, that they call ‘trust’ is actually giving up on trying to understand others. And that has nothing to do with ‘trust’, but it is rather apathy. (…) The true evil is becoming apathetic about other people.” Akiyama believes that doubting people isn’t a bad thing, he thinks that the more you doubt the more you discover about them. “The true evil is becoming apathetic about other people” refers to the people that just do what they are supposed to without thinking how it would affect someone.

As Akiyama began to become suspicious, he searched for a way to win. He had already acknowledged Kikuchi’s cheating, but what could he do? He observes the dealer, noticing his perfect Riffle Shuffles. This is because Riffle Shuffles using only 17 cards were easy to make perfect, especially with the pro Dealer’s meticulousness.
Source: Liar Game, Revival Round II Arc
Now, the dealer was always dividing the deck in a 9:8 system. Akiyama’s goal by manipulating the dealer to use only the Riffle shuffle was to decide the hands each player was getting. The fact that the dealer was only using that shuffle made him able to figure out all the patterns of the shuffles by exchanging five cards and then shuffling all the cards he saw in the opposite way. Afterwards, using the pattern that he just acknowledged, he shuffled the 17 cards in his head to see how many times he had to make the dealer shuffle in the next round to guarantee a four of a kind, using this to make his hands always stronger than Kikuchi’s. For example, after manipulating the dealer to shuffle twice, he would get this order: J, J, J, J, Q,Q, Q, Q, K, K, K, K, JOKER, A, A, A, A. He would make the dealer cut eight in total, so if Kikuchi asks to cut 7, he would ask for only one. This would give the hand: K, K, K, JOKER, A, A, A, A, J, J, J, J, Q,Q, Q, Q, K. Afterwards, the dealer would give this sequence to each player:

Akiyama understands that Musical Chairs is a game of conquest and compares the game to the time when Japan was fragmented into multiple smaller nations. He said that the nations of Japan are the alliance of players in this game. The strongest nation controls the others because of the power, the group with the most members controls the game because of the elections. He applies this to the game. Having a team, a group of chairs, as well as votes are essential. He predicts the formation of nations at war. Like how Mikamoto chose Abe’s original chair to become defective in reaction to Akiyama stealing it. The nations are already at war, and the only way to win is to join one yourself.

Akiyama observed that the direction the dealer spun the cylinder was opposite to the direction that the cylinder moved by shooting. The dealer spins it lengthwise so that no one can cheat and see each other’s bullet placement, but that is where the issue lies. There seems to be a sharp clicking sound every time the dealer spins the gun. Akiyama posits that the center of gravity in the revolver has shifted, as 6 blanks were loaded in (there had to be a considerable amount of gunpowder to make such a loud bang). Akiyama took the gun again and tested it, spinning the chamber with the same configuration as the simulation round. Oddly enough, the position where the shots were located remained the same. This means it clearly moves in a favored side, confirming his theory.

During the game Fukunaga will completely dominate his opponent, so Akiyama will explain how. As explained above with the barrel, the barrel of the gun unlocks to the left, it moves clockwise for each shot, but it is rotated in the opposite direction to mix it up in the start, the leader of the game rotates it in front of the players to avoid cheating, and moreover he rotates it with the barrel raised upwards so as not to see the position of the bullets. In reality, all these actions distort the game. When the barrel rotates you hear a certain sound because of the 6 bullets, without the bullets and the gunpowder it would be different. In the simulation, Akiyama spun the barrel with the bullets in place and when he stopped there was a gap of one chamber, so the barrel is off-center. They load 3 balls in a row, assuming that the 2 players do the same and that they don't do it symmetrically (not opposite each other) the barrel is off-center, the weight pulls it down and being equipped with a block preventing it from coming back the inertia pulls it further away, which explains why it has little chance of hitting a shot in the beginning. Basically, after these tests and Reasoning, Akiyama realized that the initial shots were safe, as the weight of the bullets carried them lower. As said in the first explanation of the game, this work specially if the opponent has also put 3 bullets in a sequence, yes, but Akiyama has made his opponents hear him say "just put 3 bullets in a sequence", this for Misdirecting them, as if he didn't mean for them to hear. He is going to manipulate them into using the same strategy as him by exploiting their lack of coordination and their fear of losing, he plays on their lack of confidence to get them to notice the 3-ball strategy, except that this strategy is much more effective if you have understood the aspect of gravity, in the case of only understanding the idea of the 3 balls, you have much less of an advantage than if you have understood gravity + the 3-ball strategy. Akiyama uses their fear and lack of confidence to make them fall into his trap.

Aki kept only the ace and the joker, now the chances of him getting at least a three of a kind are 100%, because he can only get 4 types of cards (ace, K(King), Q(Queen) and J(Jack/Valet)) if all the cards he gets are different, he would make a straight flush, if there is at least two equal, he would make a three of a kind. The chances of him getting the strongest three of a kind are also pretty high (62%) so even if Kikuchi gets a three of a kind, Akiyama still has a bigger chance of winning. Akiyama won the first round with a three of a kind of Aces.

She predicted that Akiyama would try to direct attention to Baldy, therefore he would be able to bid above Harimoto’s bid, so she made everyone pay attention to him to avoid him bidding. Akiyama didn’t care and bidded 2 coins in the last second, getting another lot. He exposed their strategy that time when the bid was shown to be Harimoto’s, making everyone mad at Kimura, not at Akiyama. Kimura’s plan was to make Harimoto the owner of two lots. He had a lot of insight into their plan, understanding that they would try to steal all the lots under the guise of a spirit, as well as faking their intentions to agree with Nao’s bid rigging strategy. Akiyama also observed in the start of the game that Harimoto chose the first lots, so it would be easier for them to deceive the players, because people who chose the last lots wouldn’t be in a position to try anything in the first slots, they’ve got nothing after all.

After hearing the rules of the Friendly game that Fukunaga created, he immediately figured out that the game was a scam. His reasoning was that since Nao’s card was the joker and Fukunaga’s was the double-sided card, when Nao picked the joker faced up, she would just put it back, they would not count that as a win. However, this doesn’t happen to Fukunaga’s card, which means that the chances of Nao winning were ⅓, because in two cases (when Fukunaga picks the card face up and face down) Fukunaga wins, in one case (Nao picks the card face down) Nao wins and in one case, they redo the match.

Adapted a Mahjong strategy to Fukunaga’s game: if you mark the edge of a card, you will be able to figure out by touch which card it is, hence Nao can mark the edge of Fukunaga’s card, in which she would expect the other one to be rigged, but instead Nao would simply choose the one that was unmarked. Nao would let Fukunaga win 9 rounds with her having 5 wins, making the ratio exactly as Fukunaga expected it to be, so she wouldn’t suspect anything, thus Nao will win all the next rounds. She has to mark Fukunaga’s card specifically because she would suspect after Nao wins 4 rounds in a row, but when she would inspect it, she wouldn’t find anything, since the marked card is still in the bag.

Compared Fujisawa’s situation to cognitive dissonance. His analogy was, “At school, the teacher asks a question like, ‘A or B, which is it?’ No matter how much you think of it, you think it must be B. The teacher goes down the row, listening to everyone’s answer. He starts with the first student, who, full of energy, replies ‘A.’ Then the second student, now uncertain of his answer, replies A. The third, A… The fourth A… Finally your turn arrives, and for some reason, A is your answer. Despite how sure you were that B is correct.” Humans are uneasy when at dissonance with their external environment, so they tend to regulate themselves to that. So when Akiyama presented himself with confidence in the sight of the safe, which Fujisawa expected him to be disappointed of, he experienced dissonance and regulated himself by protecting the safe.

Akiyama uses a psychological technique called Door-in-the-Face to manipulate Butch and Slick. The technique entails asking for a large request once, which is intended to be refused. Say, you ask for $100. That person you ask says no. So let’s say you ask again, but instead, for $10 dollars. Seeing that the request has significantly decreased would make the person being requested feel a higher social responsibility. In practice, it goes like this: He first instructs Nao to go to them and ask them to contact Four-Eyes, but they of course refuse. It was a risky proposition, with no personal gain. Butch and Slick had already been manipulated by Yokoya into paranoia, not willing to contact anyone in case of losing their currently guaranteed win. Adding on to their guilt, Nao begins crying. They both know that she’s quite selfless and would likely go through with it if she was in their situation, boosting their feelings of social responsibility. She asked again, and they again refused, making them feel even worse. Now, Akiyama asked them to lock themselves in the examination rooms. This worked, because of the compiled guilt, lack of risk, as well as the function of getting rid of Nao who was annoying them.

That or, when you finish your exam and accidentally leave your pencil.

In the simulation round, Akiyama saw that Nishida said his bets in the order 4, 3 and 2. He remembered an experiment that a psychologist performed with a hundred children, where he asked all of them to make him a question with 3 multiple choice answers. The psychologist observed that almost none of the children chose the first option as the right answer, as it was some defense mechanism. Akiyama used this experiment to explain the irregularities in Nishida’s order of numbers, he then bets in the 2 and 3.

Next, he sets up a 3-layered setup underneath the original trick. First it involves Akiyama’s treatment of Akagi. I explained before, he intentionally cast suspicion on Akagi so that in that moment, when Akagi is declared INFECTED, it makes everyone believe in the credibility of the circuit. This, and, Aki’s poor treatment of Akagi discourages the other INFECTED to step up, in fear of being treated the same way. Akiyama states, “As long as we can identify who is ‘NORMAL’, the 'NORMAL' players can freely ‘contact’ and produce vaccines.” He did this to entice the NORMAL players into stepping up for the test, which makes it easy for him to discern what their status is based on psychology. Speaking of psychology, Akiyama uses the “Gambler’s Fallacy” in order to subtly manipulate everyone into believing in the credibility of his fabrication. With 9 players and 2 infected, the ratio is 7:2. As one supposedly INFECTED player has already been found out, the gambler’s fallacy entails the belief in a shift in probability based on previous events. So the likelihood that 1 more INFECTED was found sequentially after the other, that being Nao, is seen as lower, especially due to the 1/42 chance that that would happen. That’s what the gambling fallacy is. So once she’s really proven NORMAL, it confirms their fallacy, even though Akiyama and Nao could both be the INFECTED.

Akiyama, instead of directly deducing the concrete information, he picked apart the aspects of the letter and studied them to their logical extent.

Knowing this, he secretly contacted the professor’s wife in order to gather the final amount of information, now that the connection was set. He learned the full story behind the letter and thus accurately deduced the identity. This showcases Akiyama’s keen insight and out-of-the-box thinking.

Akiyama also use the fact that Nao had put a teddy bear in the suitcase, and yet Yokoya had said "nothing", this means that it is even more implausible that Yokoya has a gift of clairvoyance, just as it is unlikely that he has inhuman Cold Reading, because otherwise he would have noticed that Nao was hiding something. Akiyama has therefore managed to make the link between this information and the rest of his reasoning, such as his critical mind towards Yokoya's assertion that he was omniscient.

Akiyama predicted that a lot of reporters would come to his exit from the prison, so he anticipated it by disguising himself as a guard. He had another convict leave, before telling the reporters to leave the prison. They asked where Akiyama was and he told them that the criminal that just left was him, because he is a master of disguise. All the reporters ran in the direction of the convict, leaving him alone.

Logically speaking, the moment Fukunaga would reveal herself was when there were 4 people left. Since the other 3 will always vote opposite of Fukunaga, (remember the YES/NO order), if Fukunaga answers YES, all other players vote NO due to the contract, and that’s where things end, with Fukunaga as the winner. Then Akiyama chooses YES in order to counter the plan.

Akiyama brought 1 million yen with him in case he needed to use that to deceive someone. He places that million on the ground, when the smuggler joins the inspection office, he says that he dropped something on the ground. The smuggler looks at the million and tries to find which part of his suitcase was broken. Akiyama deduces that he indeed brought money, since he wouldn’t think that the suitcase was broken if there wasn’t any money in there.

Akiyama persuaded Yokoya to follow that plan and accept his defeat even with all the hate he has towards Nao and him. He did so by emotionally manipulating him. Akiyama played on Yokoya’s insecurity of full domination by stating that he had lost to Nao. Akiyama showed him that despite their loss Akiyama and Nao would be financially well off, while Yokoya would be seen as trash from everyone’s perspective. Akiyama also abused Yokoya’s father complex by stating that by choosing to win despite all of this he would only remain as his father’s inferior. If Akiyama didn’t manage to successfully manipulate Yokoya then he would be able to easily break the stalemate by bribing a traitor who would have his team lose on purpose.

In the next round, Akiyama bets 150 chips in 2 and 3, Nishida proceeds to bet all his chips (292) in the 2 and 3, because this is the only way to reduce the loss he was going to suffer. Since Akiyama has more chips than Nishida, he wouldn’t be able to win that round, because even if he bets all of his chips in the same numbers as Akiyama, his bet would still be lower, so the best choice is to bet all his chips in these numbers to reduce the loss. Akiyama predicted that he would do that, he made the right number be neither 2 and 3, but 4, making both of them lose all the money, but since Nishida didn’t have a single chip while Akiyama had some, he ended up winning not only that round, but the entire game. Akiyama then states that there is another way to win, this being the same as saying: “we can destroy your group whenever we want” making the other players fear that move. He told the strategy to them to make them commit a mistake by considering that strategy in the future.

Akiyama did that strategy in the test game because he planned to use Nao to bluff about using that strategy, making them gain a bigger profit because of the fear of the participant of losing in the start. His plan was to make Nao say that they would settle everything in one shot, and bet everything in the right spot. Because of the last strategy, they would suspect that she planned to make her team win by making both lose, so the participant would bet in more squares, making Nao, the one who bet everything in the right square, take most of the profit. This is a plan without any risks.

He evaluates Baldy to be a perfect candidate for a new teammate. Earlier, Baldy stole Four-Eyes’ chair, which means he probably isn’t in another group since he would’ve had a supply already. And since he only has one chair he won’t try to switch back-and-forth on 2 chairs and try to solo the game. Akiyama uses the fact that he knows Baldy’s chair number to manipulate him to join his nation. He tells Baldy’s that if he doesn’t join their alliance, his chairs will be eliminated in the next turn. But if he does join he would have 3 coins of each player of the alliance, also guaranteeing a chair every round the alliance survives. He also completely mind reads Baldy and predicted that he was going to try to steal Nao’s chair by following her when Akiyama leaves the place.

When everybody started to blame Akiyama for buying the bid, he quickly told them that what happened was Harimoto’s spirit’s fault (Harimoto told everyone that him buying the first lot was the spirit’s fault, no one thought that he could’ve exchanged tablets with Kimura in the start, and he also didn’t do any suspicious movements, so they believed him) Akiyama realized that if he doesn’t expose Harimoto’s lie about the spirit, it would create chaos in the game, so he chose to tell Harimoto to leave using the premise that his spirit is too strong, making Kimura unable to bid in her period (they swapped tablets) and exposing their strategy by themselves.

When Baldy bid 233 coins in Harimoto’s lot, Akiyama quickly realized that Harimoto would find an excuse for not giving the lot to Kawai, because Baldy’s move proved that he didn’t trust them, and that would be enough to Harimoto to reject the offer. He instructed Kawai to bid all his coins in his lot, but Harimoto anticipated that and bid one more coin than all of Kawai’s coins in Akiyama's lot.

He explains that Harimoto would want to place first, so to do that he would discard his K first and then order Mikamoto to discard her 3 after that. This is because Akiyama has 596 coins at his disposal. He could easily steal the 3 if he wanted to, obstructing Harimoto’s straight flush. From Harimoto’s point of view, Akiyama would happily spend a cheap cost of 234, even if it wasn’t profitable, because remaining in 1st place is worth it. Harimoto would let Akiyama have that card, and then bid on Abe's 8 and Kimura’s 6, making another straight flush. Like so:

In a normal situation, this plan would seem like a joke. If you were in Taninaka’s place you would never be crazy enough to simply give Akiyama all your money accepting the risk of him stealing it. Same with Saeki, Akiyama could just buy his cards, make him a pig and take all the money for himself in the end. But otherwise, Kimura would make all of them Pigs, they had no choice rather than trusting Akiyama or trusting Kimura, they were completely desperate. Since Harimoto told them that he won’t trust them in the start, and Kimura was the main reason why they were in that situation, they would rather ally with Nao, the player who always intended to save everyone and never betrayed them, than Harimoto, the guy who made them become Pigs. Another reason for them to choose Akiyama instead of Kimura was that they didn’t know that Kimura made them become Pigs through Kawai, who was under Akiyama’s orders to tell the coin/lot information. If they knew that they became Pigs because of Akiyama they would accept Kimura’s deal instead of cooperating with him, but from the start he planned to make them desperate without them knowing it was his fault. In the end, they all kept as Pigs, but Akiyama simply gave the money they gave him back and paid their debts. The money Akiyama got as the winner + bonuses + the money that they manipulated Harimoto’s team to give them was enough to pay all players' debts, so everybody got cleared except Harimoto’s group.

Akiyama predicted that the LGT would try to interfere in his plan of being the only loser, he plans to use that in his favor to crush them the moment they try to. He felt an odd sense of despair in the dealer’s words while explaining the game, that his plan would not be usable.
