Prime Suspects
Twelve numbers. One culprit. Five probes.
A noir deduction game disguised as a maths toy. A lineup of twelve numbered suspects stands in the room and one of them did it. Every probe you play asks a single true question about the culprit — is it a perfect square, does it wear a seven, is it prime, literally — and every suspect standing on the wrong side of the answer walks out. Cross off ten innocents, name the culprit, and try not to spend all five chips getting there.
A case runs in three beats. Draft six probe cards from the eleven dealt to the felt. Interrogate by spending chips, watching the room thin out as each answer lands in the dossier. Accuse a survivor and slam the stamp. Beside the chips sits par — the number of chips an optimal interrogation needs for this exact lineup, computed by a balanced-split solver before the case is dealt. Beating it means you questioned as well as the solver.
