Museum Jeopardy.

Every clue is drawn from this house — the coins, the doctrines, the facts on the walls. Read the clue, answer in the form of a question, then reveal and score yourself honestly. The machine can’t judge your answer; only humans score.

Answer in your head (“What is…?”), hit Reveal, then mark it honestly — got it adds the value, a miss subtracts it. That self-scoring IS the point: only humans score.
