How to play

Each case has one culprit and every suspect is either an honest witness or a liar. Mark each suspect as Honest or Liar, pick the culprit, then accuse. The statements are built so that exactly one story fits them all, so pure logic always works.

A wrong accusation costs 100 points and tells you how many of your marks were right. Cross-check costs 50 and tells you how many possible worlds still fit your current marks; if it says 0, something you marked contradicts a statement. Each case is worth up to 1000.

Keys: arrows or number keys pick a suspect, H honest, L liar, C culprit, U unmark, X cross-check, Enter accuse. On touch, tap the buttons on each card.
