S3·E2 You Know Nothing

Thanks to Kaito's deductions and Nonoha's memory, their group manages to find the correct exit and escape. Afterwards, Raetsel takes everyone to her personal boat, where she shows them a feed of Gammon's group as they face Whodunnit's puzzle, where they must arrange cubes successfully or else be electrocuted. Working together, they deduce the colors of the cube are a clue to numbers in a magic square puzzle, managing to solve it with a second to spare. Although Raetsel leaves Jin with Kaito and the others, they are left uncertain by how the Master Brains, who target puzzlers for bounty rewards, claim to be contracted by Jin.
