About Sworn

Sworn is a free daily logic puzzle from Mind Loft, a classic liars puzzle in the Knights-and-Knaves tradition, dressed as a village inquest. Something has been stolen, a handful of locals are put under oath, and every one of them gives a single statement. The catch: an exact number of them are lying, liars’ statements are always false, and one of the sworn is the thief.

The reasoning is pure case-work: suppose a suspect is the thief, follow what each statement would make of its speaker, and check the lie count. Wrong theories collapse under their own contradictions; the truth is the one story that holds together. Every case is generated with a constraint solver and machine-verified to have exactly one consistent world, and to be crackable by clean deduction, never guesswork.

A new inquest is sworn every day at midnight Eastern, with six suspects at Sunday’s Grand Inquest. No app, no signup, play free in your browser, keep a streak, and race the daily leaderboard. More dailies: Alibi, our nightly whodunit, Jesters, our court-placement puzzle, and Cipher, our daily cryptarithm.
