* {{Anvilicious}}: Don't rely on luck, never resort to magical thinking, and for the love of God, quit while you're ahead.
** The gambling industry is ''not'' trying to help you. It only wants your money and ''will'' take advantage of your hopes and desperation.
* {{Big Lipped Alligator Moment}}: In Chapter 7 of Series 3, we are left on a cliffhanger [[spoiler: with Kaiji staring at a box of Uno cards in a way that suggests it may be the next game. The President talks about it in a way that also suggests it, but Kaiji quickly declines, and by the third page of Chapter 8, it is a distant memory, never to be mentioned again]].
** Some of the ''Proverbs of Kaiji'' segments in season 2 come off as this, due to the way said proverbs can sound [[ItMakesSenseInContext out of contenxt]].
* {{Bishounen}}: Ichijou (in-universe, of course).
* CompleteMonster: [[EvilOldFolks Kazutaka Hyo(u)do(u)]] is the BigBad of the entire series. A wealthy socialite and [[CorruptCorporateExecutive president of the financial consulting firm Teiai]], Hyodo is a man driven mad by money and power whose only enjoyment in life is to see the lower classes of society struggle for their lives and money in illegal gambling tournaments. In Part 1, Hyodo has a group of his debtors gamble in a ship, collecting badges from each other. Those who lose all their badges are transferred to an underground mine where they are forced to work for their money in horrible conditions, most of them dying due to work-related injuries or breathing problems caused by the smoke. In Part 2, Hyodo forces another group of debtors to walk on a narrow plank ten meters up the air, and in order for them to win, they [[SadisticChoice have to push down others, breaking their bones while doing so]]. After [[TheHero Kaiji]] and a handful of others manage to walk on the other side, they are then forced on a similar plank which is electrified and hundreds of meters up the air. Kaiji, being the sole survivor of the second part, is then obliged to duel against Hyodo's right-hand man, [[TheDragon Yukio Tonegawa]], and choose either his {{eye|Scream}} or [[EarAche eardrum]] as his stake. After Kaiji wins, Hyodo proves [[BadBoss how cruel he is to his subordinates]], forcing Tonegawa to [[ManOnFire kneel for a minute on a scalding platform]]. Briefly appearing in Part 3, Hyodo is seen drinking the blood of his victims, while treating his other subordinates with similar cruelty. A truly despicable old man, Hyodo is the living incarnate of {{greed}} and cruelty in a [[CrapsackWorld world where people are willingly to do anything in order to pay back their debts]].
* CrowningMusicOfAwesome: Oh yeah, tons of it. ''[[http://www.youtube.com/watch?v=meBzDGG7WeU Wish]]'', ''[[http://www.youtube.com/watch?v=eHRes2_wZE4 Kaiji's Theme]]'', ''[[http://www.youtube.com/watch?v=YhNm19gVw60 This World III]]'', ''[[http://www.youtube.com/watch?v=njUrn6wbc2I Beginning]]'', ''[[http://www.youtube.com/watch?v=g6AcB1eJfHs Transparent]]'', ''[[http://www.youtube.com/watch?v=SQzkQmxmieU Law Breaking Theme]]'', ''[[http://www.youtube.com/watch?v=P62vPjg7DBg Bassment]]'', ''[[http://www.youtube.com/watch?v=XcGHbsDLyz4 Max Zawa]]'' and ''[[http://www.youtube.com/watch?v=uAlXRgcPHlc Hakairoku Theme]]'' to name a few.
* DudeLooksLikeALady: Ichijou.
* EarWorm: It's near impossible to get ''[[http://www.youtube.com/watch?v=UMztjxYKSDw Numa]]'' out of your head.
* EnsembleDarkhorse: Mikoko Sakazaki has become really popular on the Internet, which the creators are apparently aware of. Tonegawa also qualifies because of his BadAss [[TheReasonYouSuckSpeech speeches]] on society, and for being a MagnificentBastard in general. Then there's the [[Creator/FumihikoTachiki narrator]]...
* FauxSymbolism: The finale of the first series uses this to some extent.
* HoYay: Murakami's undying loyalty to Ichijou has made them a popular pairing among fans. Kaiji is commonly paired with Endou, Kazuya, Sahara, or [[FoeYay Ichijou]].
** NoYay / FoeYay: Between Hyoudou and Kaiji. The former ''drools'' at the sight of the latter in pain.
* MagnificentBastard: Tonegawa. Despite [[spoiler:having cheated his way through the E-Card game]], in the end he still comes off as noble and ultimately ''badass''. Even more so Hyoudou.
* MemeticMolester: Hyoudou. [[{{Squick}} Let's leave it at that]].
* MemeticMutation: [[spoiler:Aaaaandooooooouuu!]]
** I hate it! (He hates it!)
* NightmareFuel: Teiai Corp.'s various [[ColdBloodedTorture torture]] [[CoolAndUnusualPunishment devices]] as well as the second half of the Brave Men Road arc.
* {{Padding}}: Way more than even your usual primetime game show. Even ''Series/DealOrNoDeal'' can't compare.
* TheScrappy: The number of people who unironically like Andou can probably be counted on one hand. To a lesser extent, Furuhata.
* UglyCute: Some find Mikoko to be this.
* TheWoobie: Some will argue that the whole point of this series is to see Kaiji lose tremendously, get back up in an inspiring and heart-winning manner...then lose even more tremendously. In the end, you just want to give him a hug or buy him some drinks after all that's happened to him (losing scads of money, betrayal and bullying, [[spoiler:maiming, losing his comrades, being forced into slave labor, being harassed by a girl he doesn't like]]...the list goes on). Many fans will argue that Kaiji is indeed "moe", or moeGAR.
** JerkassWoobie: Hiromitsu Ishida comes off as this at first.
