S2·E12 Heaven's Fall, Man's Fall

Sakazaki ignores Kaiji's warning and continues sinking money into the Bog, while the casino manager gives instructions to initiate the 'block' which controls the flippers, stopping the balls descending into the winning zone. Although Sakazaki is close to winning he collapses and the casino manager, Ichijō Seiya, introduces himself and reveals that they are using brass balls today which are not affected by magnetism. They leave with a little more than ¥6 million after losing over ¥43 million in two hours. The next day, Kaiji spends hours back at the casino, staring at the machine, then goes to the staff room to cash in one ball he found, insulting Ichijō but also gathering information about the casino's operations.
