Kaiji has only ¥20 million left to try and beat the Bog, however he is confident as he is aware of how the three bottom plates are rigged. He explained this to Sakazaki when they were at the racetrack. Slowly Ichijō comes to realize that Kaiji managed to not only tilt the machine to increase his odds of winning, but also create a slightly favorable tilt on the casino building. Unbeknownst to him, Kaiji's group had poured 20 tons of water into plastic tanks in a room on one side of the casino building, causing it to subside slightly on that side.
猛攻、カイジ！必死の防御、一条！命を賭けた決死の攻防！狂気の限界を超え、闘いは続く。 第一関門、第二関門を突破したカイジは、遂に3段クルーンへ辿り着く。それは一条が絶対的に自信を持つ、『沼』最大難関、難攻不落の砦!! だがしかし、立ち向かうカイジには空前絶後、奇想天外な奇策があった・・・
제2관문도 돌파하여 마성의 3단 원반에 도착한 카이지. 이치죠는 '늪' 최후의 관문이자 난공불락의 요새인 이 원반에 절대적인 자신감을 느끼고 있었다. 하지만 여기에서 상식을 뛰어넘은 카이지의 묘책이 빛을 발한다. 역전의 희망, 기적을 향한 길은 다시금 열릴 것인가?
开司将第二关弹簧门守卫零件换包，使得弹簧门的支架扭曲无法再阖上，冲破第二关。一条仗著对三层圆盤的信心，答应让开司继续挑战。没想到开司识破了圆盤的祕密，原来第三层圆盤的中奖洞前方竟然有一块透明的凸起，使用钢珠无法从後方进入，而沼泽机整体又分成三个部份往前倾，使得钢珠根本无法从中奖洞的前方进入，而形成难攻不落的铜墙铁壁。
La persévérance de Kaiji a payé. Il est parvenu à neutraliser les flippers en substituant aux pièces de rechange des pièces trafiquées. Ichijô, quant à lui, compte toujours sur ses trois plateaux pour déjouer les plans de Kaiji.
