-> ''"This is the LIAR GAME... A game about deceiving others. I'm just doing what it takes to win."''

Written by Shinobu Kaitani (also the author of ''OneOuts''), ''Liar Game'' is a manga and drama series about the struggles of Nao Kanzaki against a [[NebulousEvilOrganisation mysterious and nefarious organization]] called the Liar Game Tournament Office that places innocent people through psychological games using their debt as bait. All its members wear masks and any participants of the game are free to drop out, assuming they pay their debt which the game forced upon them. With debt that frequently is in the 100 million yen range and quite often more, it's no small deal. Said organization will also collect the debt "any way possible..."

Using the help of recently released conman/genius/ChessMaster Shinichi Akiyama, Nao seeks to rid herself of debt and also save those who are participating in the games. Expect all [[GambitIndex all kinds of plans and cunning]] to apply here, as it is a Battle Royale of wits.

This story has a prequel called ''[[LiarGameRootsOfA Liar Game-Roots Of A]]'', which has a one-shot chapter that deals with the backstory of Akiyama and contains several other unrelated one-shots.

----
!!This series provides examples of:
* AbsurdlyHighStakesGame: Losing the Liar Game gets one saddled with ''at least'' a debt of 100 million yen, and since most of the participants aren't wealthy people, they could not get pay their debts and gets sold.
** The trope is subverted in the case of [[spoiler:the Liar Game itself]] being a FalseCrucible.
* AttractiveBentGender: When Fukunaga gets dolled up, he's pretty much the hottest woman in the series.
* AwesomenessByAnalysis: "'''Doubt''' them."
** And she did.
* BagOfHolding: Yokoya carries around one hell of a lot of cash in that little black bag of his, doesn't he? You might think he simply carries round lots of bags instead, but he's a little bit on the puny side...
* BatmanGambit: Before it dissolves into a GambitPileup between Akiyama and Yokoya, the third round begins with a series of these simpler gambits.
** Akiyama's plan to [[spoiler: trick Kimura is this in spades]].
* BattleCouple: Despite not actually physically fighting together, Nao and Akiyama make one amazing team of wits and skill.
* BewareTheHonestOnes: Nao Kanzaki is fully capable of deception once she has sufficient reason and a plan to back her up, either hers or someone else's. [[spoiler: She actually ropes ''Fukunaga'' into helping her win her match in the second Revival Round, and during the Pandemic Game, she cheerfully lies to Yokoya about who is in which examination room so that Yokoya's attempt at bribery hits Akiyama and Akagi instead.]]
* [[spoiler: BittersweetEnding: The LGT admits defeat and excuse all the debts from the players (Not that they plan to collect them anyways), and the Liar Game show is going to be aired on the internet. But apparently the "Unknown Government" has so much influence it can bully the '''ENTIRE INTERNET''' into deleting the video on the day of release. ]]
* BlindingBangs: Akiyama's eyes are usually hidden by his bangs unless he's revealing a plan or taunting his enemies.
* BreakingSpeech: Nao lays one out on Yokoya like a king hit, then follows it up with a TheReasonYouSuckSpeech. [[spoiler:Yokoya, by his own standards, had just ''won''. Yet, Nao's speech was able to take a self-interested, greedy manipulator and through force of personality and the dissonance of her seeming honesty, shake Yokoya's assumptions about what he knew, and what she knew. She also chose a great time to strike - right after Yokoya delivered a successful BreakingSpeech to resident Chessmaster Akiyama. Nao then breaks down all the reasons that Yokoya was the true loser, and Yokoya claims that since he won quite a large sum of money, and that since the Liar Game tournament is essentially a zero sum game (or "one person winning means another person loses), Nao's goal of saving everybody is impossible. Nao then tells Yokoya that there was a very simple way of toppling his assumption before leaving, successfully provoking him into entering the next round when he had been planning on just quitting. Then, when Akiyama asks Nao how she was going to break the zero sum game, Nao then [[BatmanGambit admits that she had been lying, and said those words solely to provoke him into another round where they'll have another chance at taking back all the money that Yokoya took and use it to pay off everybody's debts]]]].
** [[spoiler:Yokoya used an particularly effective one on his Bid Poker game, to corner everyone psychologically and practically makes them his minion.]]
** And then Nao does it ''again'' [[spoiler: to the same person no less. Yoyoka explains that he lives on his father's philosophy that "a person's worth is decided by how many people he controls." Nao then deconstructs this by pointing out that if he's living by his father's philosophy, then that means that he has no worth of his own since his father controls him.]]
* BreakingTheFourthWall: Only once or twice: "Fine, I'll go back and explain things since you're slow, and for our readers, since they didn't see what happened."
* BriefcaseFullOfMoney:
** Played straight in the first round. [[InvokedTrope Invoked]] in the third round, whose scenario involved smugglers sneaking money past customs in briefcases.
** Also averted in several rounds, where the money is given in the form of rare gems (on a nameplate), M-tickets (check-like objects), or poker chips.
* ButtMonkey: Forli (dealer of Pandemic Game) for the LGT Office, is the goofiest among the LGT officials, and frequently "falls" for Akiyama's or Yokoya's tricks despite not actually participating in the games. Even Leronira has been known to play him as a fool at times.
* TheCakeIsALie: Yokoya enforces a points-based loyalty scheme during the Contraband Game. He encourages the members of his team to spy on one another and report disloyalty; those who score the highest points will be given money as their reward, with those at the top getting enough to cancel their (large) debts. Fukunaga spots that Yokoya is probably not keeping count at all, and is just telling everyone they are hovering around 4th place to spur them into spying on one another and feeding Yokoya information.
* CharacterDevelopment:
** Nao, who [[DumbassNoMore progressively becomes smarter and more observant about people surrounding her]] and actually managed to device tricks on her own [[spoiler:such as collaborating with Fukunaga in the Second revival round without telling Akiyama about it]].
** And Fukunaga, who TookALevelInKindness by becoming one of Nao and Akiyama's most steadfast allies. [[spoiler:So much so that she decided to [[HeroicSacrifice sacrifice her own chance of winning the bid poker round against Yokoya to save the only one player who did not get lured by his empty promises.]]]]
* ChessMaster:
** Akiyama serves as the "brain" in his collaboration with Nao, and has used various mind games and psychological traps to help her steal all of the opponent's money in her first few rounds of the game.
** Yokoya, the series' main antagonist, has an intellect that rivals Akiyama's and even got the better of him during their first encounter in the third round. [[spoiler:Although Nao's BreakingSpeech managed to turn the situation around and forced Yokoya to continue playing despite his intentions to drop out the game after earning a massive profit]].
** In the Musical Chair arc, we are introduced to Harimoto, a cult leader who manages to get a head start in the games by duping Akiyama, and manipulates one of Yokoya's lackeys into helping their group and becomes an exceedingly dangerous threat for both of them. [[spoiler:However, it was later revealed that it is Kimura, not Harimoto, who was the mastermind of the cult's plans]].
* ChronicBackstabbingDisorder: Yokoya. [[spoiler: This trope also includes Harimoto during the fourth round.]]
** Unsurprising, [[spoiler: considering Yokoya`s been raised to believe that everyone is divided into rulers (those in power) and those who are being ruled (cattle you can use, worthy of no consideration). Rulers don`t have friends - they have either subjects or enemies. No wonder the concept of team work and loyalty mean nothing to him.]]
* ChronicHeroSyndrome: Nao's main drive is to save everyone in the games. When she had the chance to finally drop out safely from Liar Game after the events of the Musical Chairs arc, she chose to continue participating because she wants to help Abe.
* CombatCommentator: Several in most games, but especially the third round and the second revival round; used to explain what the chessmasters are doing.
* ConvenientMiscarriage: [[spoiler: "Office Lady" Mikamoto]] had a affair with her boss and got pregnant. It's stated that she lost the child.
* ConvictionByCounterfactualClue: Subverted: [[spoiler:Akiyama makes up a bunch of "psychology facts" about what people do when they're telling lies as part of plan to unravel Yokoya's phony psychic abilities.]]
* CrashIntoHello: Nao and Akiyama's first meeting.
* {{Cult}}: Lead by Harimoto, he teaches that [[spoiler: the human race bred with demons which made humans evil, so only the purer humans can get in the cult (they classify with demonic dominant and demonic recessive for the Mendel enthusiasts). Ironically, one of the "wise ones" (Yukiko, the Ponytail), thought ''Nao'' was evil, especially when she heard about Nao's honest intentions and figured it was a lie. Also, Harimoto is supposed to be 10,000 years old and Yukiko is supposed to be 500 years old ("by virtue of her wisdom").]] [[spoiler: Except Harimoto is not the true leader of the cult.]]
* CurbStompBattle: The second revival rounds 24-chamber RussianRoulette. [[spoiler:Fukunaga was crushing her opponent quite handily until Nao convinced her to tie the game on purpose.]]
* DeathByOriginStory: Both of Akiyama's parents were gone by the end of his backstory, and Nao's mother at the end of hers.
* DefeatMeansFriendship:
** Played straight, deconstructed, then reconstructed. In 3rd round, TheTeam consists of people Nao and Akiyama plundered in the Revival game. Everyone, who had seen Nao's true character in Revival game (she saves the only person who was mildly nice to her by letting him drop out safely) agrees to work with them. Then, Yokoya, MagnificentBastard he is, manages to cause a rift in the team. The team only held on because of [[AllLovingHero Nao's kindness.]]
** Nastily subverted with [[spoiler:Yokoya. Those he defeated in the first revival round did join his side, but they weren't in any sense his friends.]]
* DepartmentOfRedundancyDepartment: In Revival Round 4, Game B (the one with Fukunaga and Yokoya, not Nao and Akiyama), a player gives us the following [[http://www.mangareader.net/liar-game/140/15 gem]] about Yokoya.
-->'''Bleached Ponytail:''' That just proves you're a lying liar who lies!
* DidYouActuallyBelieve - Oftentimes, players would use this line to their opponents, after lying to them or betraying them. After all, this is a game where you lie, so it is {{Justified|Trope}}.
* DividedWeFall: Happens frequently in the third round due to Akiyama and Nao's teammates being self-serving, [[IdiotBall not-terribly-bright]] cowards. [[spoiler:Nao sees a larger version of this as the entire point of the Liar Game - everyone can avoid falling into debt, but only if they all stop [[WeAREStrugglingTogether struggling together]]. This happens most directly in the second Revival Round, in which the players can actually make a net profit if they call a truce and thus stop the dealer from having an opportunity to reclaim chips.]]
* DrivenToSuicide:
** [[spoiler:Akiyama's mother]] committed suicide so that her son could use her life insurance money to pay off their debts and continue his education.
** The four women in Harimoto's group during the games were on the verge of killing themselves before they were "saved" by the cult.
* DumbIsGood: Subverted with Nao. Early on it's very easy to believe she's either stupid or naive. As the story continues, however, things like [[spoiler:scheming with Fukunaga]] and not informing Akiyama indicate that she can't be ''dumb'' - she handles statistics information she's taught well and can speak through it with other people, not to mention the fact that she [[spoiler:takes advantage of her innocent and naive demeanour to trap another competitor - then shows how her gambit also traps the person she used to set it up.]]
* DynamicEntry: Right when Nao lost hope in the first Revival Round, having been deceived by Fukunaga and abandoned by the other competitors, Akiyama appears from the window, which is definitely not on the first floor.
* EstablishingCharacterMoment: Nao returns a 100 yen coin to the police. Akiyama dons a disguise and tricks reporters into chasing after some other guy.
* EvenEvilHasStandards:
** Fukanaga [[MamaBear snapped]] at one teammate who suggested that Nao should be the one to give up her seat in the Musical Chairs round, angrily pointing out that it's unfair to put Nao in that tight spot when she isn't in the room in the first place.
** Also subverted by Yokoya. At one point, he's seen reading a copy of [[UsefulNotes/AdolfHitler Mein Kampf]]. He mentions to an aide that though Hitler's speeches and rhetoric are study-worthy, some of his actions were despicable. What actions are these? Committing suicide before his plan was complete.
%%* EvilGloating
* EvilCannotComprehendGood: Yokoya simply cannot understand why Nao and Akiyama wants to save everyone from the game and pay off their debts.
* EvilCounterpart: Yokoya and [[spoiler: Kimura]] to Akiyama, and [[spoiler: Harimoto to Nao.]]
* FailureGambit: Players of the Liar Game Tournament are forced to participate and pay an enormous debt if/when they lose. At first, the goal appears to be to win each round and move on to the next round with large amounts of money as winnings. However, the real way to win the game is to deliberately lose and drop out of the game while hauling in a profit. But because it's a zero-sum game (one person winning means another person loses), Nao and Akiyama's goal is to [[spoiler:win and move on to the next round while shouldering an enormous debt, using all of their winnings to zero out the debt of their teammates and/or opponents so that they can all safely drop out of the game]].
* FalseCrucible: The ultimate truth behind [[spoiler:the Liar Game itself]]. As Yokoya correctly surmises, [[spoiler:the Liar Game was set up exactly like the games in a book]]. What is revealed in more detail later is that [[spoiler:the Game itself was set up to try and determine the outcome the author intended for his third volume, which went unpublished due to his death]].
* {{Fanservice}}:
** Nao's bra size certainly has been increasing as time goes on...
** Akiyama shirtless scenes probably counts.
** Fukunaga has the MostCommonSuperpower; outdoing most other cast members.
* {{Flashback}}: Used during explanations to describe any backroom dealings during the game.
* {{Fiction 500}}: The LGT office, which has enough cash to loan out 100 million yen simultaneously to hundreds of players. The games' spaces are not cheap, either. Palaces, high technology, ''islands''. Actually, they often admit that places are on rent (or squatted, possibly) and not their own, but still there are tons of cash spent around.
** It was mentioned earlier that the LGT Offices would recover their debts by "any means." Might they be renting these palaces/islands/etc. from defeated players as a means of recovering said debts?
*** [[spoiler: It is later on revealed that the leader of LGT received a bribe from "The Unknown Government", containing 5 '''BILLION''' in Singapore Dollar (Approx 3.75 '''BILLION''' in USD ), main reason why LGT can support all those expenses, and also excuse all the debts from the players. ]]
* FlawExploitation: Every successful player does this. [[spoiler: Even Nao.]]
* FlunkyBoss: Harimoto uses the UndyingLoyalty of his followers to ensure that he always has a stable of allies who will support him without question.
* FreudianExcuse: Maybe. [[spoiler: The reason of the Liar Game is to make a Live-Action show out of it, to send the author's message to the world. ]]
* FreudianTrio:
** Nao (Superego)
** Akiyama (Ego)
** [[spoiler:Fukunaga]] (Id)
* {{Fortuneteller}}: Harimoto used to be a street fortune teller who apparently excels in cold reading before he gained enough followers to actually form his own cult.
* GambitPileup: The third game, Contraband due to the moves and expectations made between Yokoya and Akiyama. It gets complex fast.
** This is partially due to two revelations midway through the match: (a), that the optimal outcome of this game is not to ''win'' but to ''lose with more money'', and therefore (b) each team should really be trying to channel their money into an ATM to which they don't have direct access...
** The game for the fourth round, Musical Chairs, has ''three'' (Harimoto), possibly '''four''' (Young Jump) [[ChessMaster chessmasters]] vying for power. [[spoiler: Young Jump turns out to be serving as a proxy for Akiyama]]
* GoodIsNotDumb: Nao starts off extremely naive, honest and easily manipulated. As the game continues, however, she grows out from her naivety and becomes a better player in the games while retaining her good heart.
* GratuitousEnglish: "Liar Game." "Money." "Doubt."
* GracefulLoser: [[spoiler:Harimoto.]] He realizes that he had lost the Bid Poker, but after witnessing how [[spoiler:Nao's kindness managed to win the loyalty of ''all'' the other players involved in the round]], he actually thanked the heavens for his loss, as it allowed him to open his eyes to his own wrongdoings.
** Surprisingly, [[spoiler:Yokoya]] at the end as well.
* HeroicSacrifice: During the events of the B block's Bid Poker game, [[spoiler:Fukunaga gave up all her money to save Kaneko -- at that time the only person who refused to join Yokoya]], so that the latter could continue the next round with excess money, while [[spoiler:Fukunaga]] herself was eliminated from the game for her loss.
* HoistByHisOwnPetard: [[spoiler: The bribe intended to silence Miyagi is used by him to fund the second Liar Game. ]]
%%* IdiotBall: Used occasionally, whether to simply provide someone clueless to whom the CombatCommentator can explain the situation or for actual plot purposes.
%%* IKnowYouKnowIKnow: The third game...see the pileup below.
* ILied: Gets said countless times in various forms, mostly using the phrase "This is the Liar Game; it's a game where you lie."
* INeverSaidItWasPoison: [[spoiler:The fact that Fukunaga knew that the stolen money was in the form of a check rather than cash told Akiyama that [[VillainousCrossdresser she]] was Mr. X]].
%%* InMediasRes: (Nao's perspective)
%%* JerkWithAHeartOfGold: Akiyama.
* KansasCityShuffle: Without a doubt the most important trope of the series. That's how Akiyama manipulates others. He uses their knowledge, or lack of it, to his advantage. That's also why everyone feels trapped in the games of the LGT. No one really knows what happens to the people who lose the games, and no one really want to find out.
%%* KickTheDog: Yokoya opts to squeeze hamsters instead.
%%* KnightInSourArmor: Akiyama to a certain extent.
%%* LoopholeAbuse: Frequent source of Akiyama's CrowningMomentOfAwesome.
* LostHimInACardGame: Implied; the LGT makes a few vague comments about the money being paid back one way or another, and though this method is not stated outright, the amounts of money being wagered are far too high to be paid off through ordinary means.
* LoveTriangle: Apparently, there's one building up now between Nao, Akiyama, and [[spoiler: Fukunaga]]. It's pretty obvious that Akiyama only regards [[spoiler: Fukunaga's]] feelings with awkwardness, but it's unclear how he feels about Nao...
* TheMagicPokerEquation: [[JustifiedTrope Justified]]; because of the special seventeen-card decks being used, the ''weakest'' possible hand in the entire game is a pair of Jacks, so it's not surprising that the players routinely pull off amazing hands [[spoiler: especially once Kikuchi starts watching the shuffling to put the Joker into his hand every time, guaranteeing a three-of-a-kind or better. Then by the ninth hand, Akiyama figures out how to guarantee a four-of-a-kind. The explanation after the game is mind-blowing.]]
* MalevolentMaskedMen: The higher-ranked LGT Officials wears creepy white masks, and continues to wear them even as they are hidden in a separate room to comment on the game's progress.
** [[spoiler: Later on revealed they do so to protect their identities, as all the higher-ranked officials are the players from the first Liar Game.]]
* ManBehindTheMan [[spoiler: ''Akiyama'' does this in the musical chairs round, proving to be the true mastermind behind the Extra Alliance.]]
** [[spoiler: "Artlier-San," is the name of the man behind the corporation (Ch 140). He's in a cloak and mask.]]
** In the Bid Poker round, it's revealed that [[spoiler:Kimura is the real {{Chessmaster}} of Harimoto's group. Harimoto is more of a [[ManipulativeBastard charismatic]] figurehead.]]
%%* ManipulativeBastard: Harimoto's ''modus operandi''.
* MoralDissonance: Nao is tricked, in more than a few occasions, by someone who turns on their heel and highlights just how much of a jerk they are. '''Immediately'''. Nao, when she tricks someone, is an angel descending from heaven with the keys to economic freedom in one hand and [[{{Metaphorgotten}} the great chain in the other]]. This is perhaps best noted as part of the game's GrayAndGrayMorality.
** The difference is; The ones who tricks Nao usually will [[EvilGloating happily gloat about it to the point of making the listener sick]], while Nao, even after tricks people, [[DefeatMeansFriendship will always be honest with her]] [[WellIntentionedExtremist ''real'' intention]]: [[MessianicArchetype to save]] ''[[MessianicArchetype everyone]]''. Oh, and Nao is indeed ''[[MoeMoe cute]]'' - so it seems that the core of it isn't 'lying is bad' as much as 'don't be a douche.'
** Further, the people that Nao tricks never suffer any ill effects - Nao and Akiyama always pay off all their debts afterward. Unless the subject was greedy and looking to turn a profit, being tricked by Nao gives them exactly what they wanted in the first place.
** The moral is not that tricking people or lying to them is inherently bad. The moral is that acting in a purely selfish manner is a losing strategy in the long run, even if it seems rational in the short run. There's no dissonance given that basically every single game demonstrates that moral. In fact, when the bad guys 'win', it's because they worked as a group (even if due to coercion or effectively, brainwashing). No one wins purely on their own merits.
* MrExposition: Leronira is usually the one to explain Akiyama's plans to his fellow masked officials. Some of the others, like Nearco, would occasionally makes a similar observation, but Leronira is usually the one who makes the concluding statements about the GambitPileup when the round ends.
* NebulousEvilOrganisation: The Liar Game Corporation, who regularly lends the participants sums upwards of 100 million yen (about US $1.5 million). Mind you, everyone has to pay it back eventually, but still...
* TheNicknamer: In the Round 4 Preliminary, the LGT gives all the players a nickname to make it easier to keep track of them.
* OhCrap: Every UnwittingPawn when they realize it.
* TheOmniscientCouncilOfVagueness: Leronira and the other LGT Dealers act like this in their backroom discussions.
* OptOut: The LGT relies on people doing this to make their profits. [[spoiler:We think. Nao hopes.]]
* OutGambitted:
** Kikuchi in the second revival round. He was very confident that his keen eyesight could help him win the poker game, but Akiyama overcame his disadvantage in vision by a far superior analytical skill.
** In the third round, [[spoiler:''Akiyama'' can seem this way. Even though he thinks he's won, the final result of his three-volume battle with Yokoya was that he and Nao were each put into four hundred million yen of debt, while Yokoya walked away with a massive profit - a complete and total loss, if you were keeping score with currency. As the later manga indicates, though, Akiyama's keeping score with '''debt''', trying to make it economically unfeasible for the LGT to continue, by being one person holding several trillion yen in debt. Yokoya met a conventional winning condition for that game - walking away with a lot of money in his pocket - but Akiyama and Nao achieved ''their'' objective too - to advance in the game.]] Not that it's not a grudge-builder.
* ThePlan: Every game involves this trope, in some form.
* PingPongNaivete: Nao. She gets better, and even gets a Crowning Moment or two.
* {{Prequel}}: The manga short [[Manga/LiarGameRootsOfA Roots of A]] looks at Akiyama during his senior year of college.
* PowerOfTrust: [[spoiler: Main reason why the "Unknown Government" goes to such lengths to prevent the novel (and subsequently, the Liar Game show) from getting out. They want its citizens to remain divided.]]
* RestoredMyFaithInHumanity:
** Part of the DefeatMeansFriendship package, such as Nao's victory over Fujisawa Kazuo in the first round.
** Apparently, also [[spoiler:Harimoto.]]
* RetCon: In the first ten episodes of the Drama's first season, the LGT Office is vague and mysterious, just like in the Manga, with no leader in sight. The eleventh episode [[spoiler:plugs a man named Hasegawa into the role at every turn, rewriting the reason why Nao and Akiyama were even thrown into the Liar Game. And THEN, the second season reveals that Hasegawa wasn't even the creator of it; he just invested a lot of money, despite the first season stating specifically that he was, with Leronira coming to him for instructions.]]
* TheReveal: The Liar Game is [[spoiler:a social experiment / EnforcedMethodActing documentary based on a famous in-universe book series under the same name. The original writer was assassinated by his government since his trilogy was meant to instill an uprising, but the two books that were now in the public domain could be used as a model to recreate the events in the story, revealing the core theme that was supposed to inspire the masses into a revolution. Unfortunately, the production was halted 18 years prior to the story since said government started terrorizing / assassinating the people involved. After 18 years in hiding and 5 billion Singapore dollars in "compensation now shut up" from said government, the film director decided to try again, using the bribe as his budget for the entire series. Nao and Akiyama ended up solving the mystery of the book series by creating their own uprising: it's not about human will, it's about human ''trust'']].
** The manga usually needs an entire chapter for Akiyama to explain how he managed to do something amazing such as [[spoiler: how to get four-of-a-kind guarenteed in every hand during the second revival game - and to do so with the kind of information presented as available is ''awesome'']].
* RevengeBeforeReason: Mizuki Kaneko goes this route instead of quitting the game, to avenge Fukunaga. [[spoiler: Or at least she pretends to as part of a scheme to eliminate herself and the other two.]]
* RussianRoulette: The second Revival Round has a ([[CaptainObvious harmless]]) variant of this.
* SeriesContinuityError: Near the end of the Minority Rule game, Akiyama[[spoiler:'s nameplate, which he had given to player 15, reappears on Akiyama for one panel before he gets it back]].
* SchoolyardBullyAllGrownUp: Yokoya for [[spoiler:Kikuzawa (and, indeed, Kikuzawa's ''entire'' school)]].
* ScrewTheMoneyIHaveRules: Nao and Akiyama run on this, constantly giving back their large winnings [[spoiler:and incurring massive debts of their own]] to save the opponents they just defeated.
* ScrewTheRulesIHaveMoney: [[spoiler:Yokoya's]] last trick up his sleeve in the Pandemic game. [[spoiler:It backfires spectacularly.]]
* SequelHook: At the end of the series the Liar Game ends [[spoiler:after being revealed to be a FalseCrucible, the events are put up on the internet to be viewed by all, only to be removed within hours]]. At this, Akiyama states that the darkness of the world runs far deeper than they can imagine.
* ShipTease: "Basically, I'm just another one of Kanzaki Nao's belongings."
** Not to mention this little scene where Akiyama takes Nao's hand to demonstrate something. "Will you do the honours?" She does mention that she felt shy when he took her hand.
** Right when it seemed all hope was lost for Nao in the first revival round, Akiyama came to her rescue and let her cry into his shirt.
** There is the panel where Nao looks concerned and wonders whether Akiyama went to sleep from exhaustion during the fourth round's night break.
** The fact that especially in the beginning, he would always come to her rescue and help her out with little to no personal profit.
* ShoutOut: In the first Revival Round, one player talks about the Lycaons, a fictional baseball team from ''One Outs'', another manga by Kaitani.
** The protester in chapter 201 looks a lot like "[[http://en.wikipedia.org/wiki/Tank_Man Tank Man]]".
* ShownTheirWork: It's obvious the author looks very deeply at each game.
* SmugSnake: Yokoya. Although he likes to think of himself as TheChessmaster or a MagnificentBastard at the very least, his gross overconfidence and condescending attitude towards his enemies quite often keep him from succeding. This can be seen in the Pandemic Game as well as [[spoiler: the Liar Game finale.]]
* TheSmurfettePrinciple: Considering all the Second Round women are just pawns eliminated immediately, Nao is the sole girl who only encounters ''one'' developed female over the course of three Rounds, plus two Revival Rounds. Compared to ''twenty-nine'' men over the same five games. Then there's the eight new men brought in at the Fourth Round Qualifier. Fukunaga [[spoiler: is revealed to be a [=MtF=] transsexual but is still treated as male by most of the characters.]]
** Lampshaded when Nao's nickname in the Fourth Round Qualifier is "The Only Woman."
** [[spoiler: The main Fourth Round (including Fukunaga's qualifiers) has some women. Shady-looking women. Women that are, for all intents and purposes, mindless puppets of the new antagonist introduced in that round. Though one of them does get some development and another is later proven to be the true mastermind of the team.]]
* TheSocialDarwinist: [[spoiler: Yokoya`s father is the first type. He is a SelfMadeMan who built his fortune from scratch and believes that people are divided into those who rule and those who are being ruled - a philosophy he has instilled into Yokoya as well.]]
* SortingAlgorithmOfEvil: The first round's major opponent is Nao's middle school teacher who's about as clever as a normal person. The second round and revival round has Fukunaga, while the third round's is Yokoya. After a short break for the second revival round, the opponent is Yokoya and finally the BigBadDuumvirate of Yokoya and Harimoto.
* SpannerInTheWorks: Akiyama sees Nao as this in regards to the Liar Game's objective to make money.
** The "Extra Alliance" in the Musical Chairs game throws a major wrench into the until-then three-way battle with Harimoto, Yokoyo, and Akiyama.
* TheThirtySixStratagems: Akiyama uses #21 quite a bit. But instead of faking the dead as this stratagem usually involves, he convinces his opponents that his loss is guaranteed. His opponents then get careless and don't realize what he's really planning.
* [[DumbassNoMore Took A Level In Planning]]: Nao. Fukunaga comments on this in the fourth round break.
** "...Is this really the same Kanzaki Nao who easily got duped by me just a while ago?"
** And then [[spoiler: Yokoya]], of all people. He went from scarily competent to [[spoiler: accurately predicting the game of the third revival round, right down to the exact name and workings.]]
* TooGoodForThisSinfulEarth - Akiyama's mother was a very kind and honest person, just like Nao. Despite not having lots of money, she worked day and night to pay for her son's education until she fell ill and an old friend of hers deceptively pulled her into an MLM. Despite honestly working hard, she finally realized that she was never paid and her debt remained the same. When she tried to get out of it, the company required a huge sum of money to do so which she would never have been able to pay off. So she took her life in order to save Akiyama's education.
* UnspokenPlanGuarantee: Partially averted. Often times the plans are explained in advance, and they usually even work to a greater or lesser degree. However, the final move of each game that clinches the win always stays hidden until the last moment.
* UnwittingPawn: Pretty much anyone who isn't Akiyama, Yokoya, and Harimoto is this at all times. [[spoiler: Nao and Fukunaga begin to grow out of this after the third round, but they promptly gain some new allies to take their place.]] As of the fourth round, [[spoiler: this trope now includes Yokoya]] and[[spoiler:Harimoto]].
* ViewersAreGeniuses: A plausible alternate title for the series would be ''[[http://en.wikipedia.org/wiki/Game_theory Game Theory: The Manga]]''... Although many concepts are well explained, it seriously helps to have a good understanding of [[http://en.wikipedia.org/wiki/Prisoner%27s_dilemma the Prisoner's Dilemma]], [[http://en.wikipedia.org/wiki/Social_psychology social psychology]], [[http://en.wikipedia.org/wiki/Cold_reading cold reading]], and [[http://en.wikipedia.org/wiki/Imperfect_competition imperfect competition]] in [[http://en.wikipedia.org/wiki/Microeconomics microeconomics]]. ([[http://en.wikipedia.org/wiki/Nash_equilibrium Nash equilibria]] haven't come up... ''yet''.)
** Nash equilibrium is now officially there.
* VillainousBreakdown: [[spoiler:Yokoya]] seems to be on the verge of snapping in the more recent chapters.
** [[spoiler:And he ''definitely'' broke down at the Season 1 finale of the J-Drama.]]
** As of Chapter 164, [[spoiler:Kimura]] is looking to have one based on [[OhCrap her reaction]] on the last page.
* WallsOfText: It's a dialogue-driven story which touches on areas of game theory, individual psychology, ''sales practices'', economic theory and sociology.
* WellDoneSonGuy: [[spoiler:As chapter 197 revealed, Yokoya`s dad seems to be this to Yokoya]].
* WhamLine: [[spoiler:"The true leader of Harimoto's group is not Harimoto-san but Kimura-san."]]
-->'''Kawai:''' '''''[[MindScrew EEE]][[GoMadFromTheRevelation EEH?!!]]'''''
* WideEyedIdealist: Nao.
** Subverted by the fact that Nao's idealism usually wins over the cynicism of the other players. Which is not actually unlikely; as con artists say "you can never con an honest person". Almost all forms of con require the mark to be willing to be greedy or dishonest.
* TheWorfEffect: How are we made immediately aware of the potential danger Harimoto poses? He utterly wiped the floor with Fukunaga.
* XanatosSpeedChess: Numerous times, perhaps best demonstrated by the endgame of Musical Chairs, though.
* YouCanAlwaysTellALiar: In the second revival round. Fukunaga apparently betrays Team Akiyama by telling Nao's opponent that she has a tell: she blinks twice whenever she lies. Nao's opponent uses this information to wipe the floor with her...but it's all a ruse, one planned by Nao herself, and as soon as her opponent is feeling overconfident, Nao lures her into a trap that instantly reverses the situation.
