Phi Brain: Puzzle of God - Season 3 Episode 22

Called together on a yacht by Enigma, Kaito, Gammon, Freecell, and Raetsel participate into a block-pusing maze puzzle to decide which two shall take on the Puzzle of God. Raetsel is the first to reach the center of the maze and escape after outwitting Freecell, with the remaining players now having to face explosive walls. Kaito and Gammon also manage to open the way to the exit, but Gammon becomes trapped under some rubble, with both Gammon and Freecell urging Kaito to not hesitate and escape on the last escape pod as Enigma sets the yacht to explode.
