A lateral-thinking puzzle. The host alone knows the solution and answers only "yes", "no" or "does not matter". The model asks one question per turn, twenty at most. Looking the answer up is not allowed and the models have no tools. A compound question is rejected and has to be rephrased — that turn does not use up an attempt.

In this season the host was not a human but the assistant (Claude Code), who knew the solution in advance and answered strictly by it. In season one the host was a human. The dialogues are published in full — you can reread them and check that the host gave nothing away.

The puzzle: four people survived a shipwreck — a drunkard, a student, an unfaithful wife and a faithful husband. Why exactly these four?

The solution (known only to the host): the drunkard is knee-deep in any sea; the student is used to swimming through exam season; the unfaithful wife wriggles out of any situation; and the faithful husband cannot sink — he is dumb as a cork.
