''Gambling Emperor Legend Zero'' is by the same creator as ''Manga/{{Akagi}}'' and ''Manga/{{Kaiji}}'', Fukumoto Nobuyuki. However, the gambles tend to be based around forcing the player to solve a puzzle set up by the house, rather than defeating other players in games. It also focuses heavily on the games themselves and very little on the psychology of the players, in contrast to Fukumoto Nobuyuki's other works.

Zero, having forged a group of noble bandits out of his internet SuicidePact, works to steal stolen money back from the {{Yakuza}}. However, he is outsmarted and caught, but since the big boss, [[BigBad Zaizen]], is looking for rep players to use in a massive gambling event between trillionaires, he agrees to let them go if they enter the Dream Kingdom that will be used to whittle down the prospective choices. Gambling ensues.

The manga "ended" with a {{cliffhanger}} and was put on hiatus for a while in favour of ''Kaiji'''s fourth series. [[http://www.animemaka.com/kaijis-fukumoto-to-resume-tobaku-haden-zero-manga.html In July 2011, news spread that Fukumoto is resuming it.]] And, recently, he did resume it.

!!This manga provides examples of:

* ActionPrologue: The first chapter seems to be the culmination of a GambitPileup.
* AlwaysSecondBest: [[spoiler:Zero's old classmate (see ChronicBackstabbingDisorder below) hates him because of this.]]
* AmusementParkOfDoom: Dream Kingdom.
* BaldOfEvil: Zaizen.
* BigBad: Zaizen.
* BoringInvincibleHero: Subverted. While Zero is a genius, there's also Shirube who seems far more invincible than him and whose hero/villain status is rather vague.
* ChronicBackstabbingDisorder: [[spoiler:Zero distrusts one of his old friends because he suspects him of having this. He's right.]]
* {{Cliffhanger}}: Just before the series went on hiatus, [[spoiler:Zaizen locked all the winners in cars and sent them off a cliff. The sequel reveals that they survived, or at least some of them.]]
* CombatCommentator
* CoolShades: Zero has them in part 2.
* CowardlyLion: Yuuki.
* DefeatMeansFriendship: Happens with [[spoiler:Junko]], incredibly enough.
* {{Defictionalization}}: Zero's "underground website" can be accessed in real life.
* TheDragon: Gotou.
* EmbarrassingFirstName: [[spoiler:Sakura]] Suezaki.
* EvilOldFolks: Zaizen and Elizabeth Junko.
* {{Expy}}: Fans of ''Manga/{{Kaiji}}'' will easily recognize the counterparts of Hyoudou and Tonegawa.
** Kyousuuke has a lot of similarities with Ichijou, and Yuuki is pretty much a younger [[CowardlyLion Ishida]].
* {{Fingore}}: Jack's game.
* FireForgedFriends: Gangster Suezaki is originally introduced as a violent and opportunistic antagonist, but becomes an important ally for Zero in the events of the amusement park and is pretty much TheLancer in series 2.
* GameShowHost: The freaky looking Kotarou, excitedly presiding over his lethal "Anchor" quiz.
* GigglingVillain: Kotarou.
* GrumpyOldMan: Zaizen.
* IMinoredInTropology: During the "Anchor quiz" arc, the comic relief idiot {{Yakuza}} [[spoiler:answers a ridiculously difficult quiz question and reveal that, because his father was a diplomat, he knows a lot about world geography and international relations]].
* JerkAss: Kyousuuke, and how.
* KaizoTrap: Zaizen employs this twice, the first time [[spoiler: after Zero clears the quarter jump]], and the second time at [[spoiler: the end of the Dream Kingdom arc (aka part one), when everyone who won gets locked in remote-controlled cars, which he proceeds to drive off of a cliff.]]
* LostHimInACardGame: Here, "him" generally refers to one's own life or body parts.
* MonsterClown: Kotarou.
* {{Narrator}}
* OverlyLongName: Kotarou's full name is Kotarou Hill Mountain Williams Harrison Jagasatake James Shiroyama. This then later pops up as a question asked during the Anchor quiz.
* NervesOfSteel: Zero. Even the narrator mentions how the more pressure is on him and the more dire the situation is, the sharper his mind becomes.
* NiceGuy: Zero.
* NotQuiteDead: As it turns out in part 2, [[spoiler:Mitsuru didn't die from being hit by an iron ball, but has been in a coma ever since then.]]
* SpiritualSuccessor: Arguably to ''Manga/{{Kaiji}}''.
* ScrewTheRulesIHaveMoney: Zaizen built a giant amusement park that is designed to kill off most of its players. He's just that rich.
* SuicidePact: In the backstory.
* TimeSkip: Series 2 is set "some years" after series 1.
* TrueCompanions: [[spoiler:Zero works hard to avert this, since working with other people means putting others in danger.]]
* UnsoundEffect: Since this is by Fukumoto Nobuyuki, we have ZAWA, the sound of dramatic tension, appearing multiple times per chapter.
* UnspokenPlanGuarantee: Most of the time, these plans don't last more than a chapter, though. [[spoiler:The plan between Shirube and Zero to overthrow Zaizen was left unspoken, but it isn't known whether they will succeed]].
* {{Yakuza}}: Itakura and Suezaki.
