A genius gambler enters the underworld of Mahjong to take on the Yakuza. It’s written by the same creator as Kaiji but features a much more competent protagonist.
Why it's similar: Both shows share the iconic 'zawa zawa' atmosphere and high-tension internal monologues during life-or-death games. The art style and focus on psychological exploitation are identical because they share the same original author.
Power comparison: It’s a battle of logic and cheating rather than physical strength. Like Kaiji, victory depends on reading the opponent's heartbeat and betting your literal life on the next move.
Why watch after Kaiji: Ultimate Survivor: Watch this if you loved the mental gymnastics of Kaiji but want to see a protagonist who is a cold, calculating genius from the start.
