Something has vanished from the manor. Deduce who was where, when they left, and what they carried. The case file stays sealed until you begin.
About Alibi
Alibi is a free daily logic puzzle from Mind Loft, an Einstein-style deduction puzzle dressed as a nightly whodunit. Something has vanished from the manor, and four guests (five in the Sunday Edition) were each alone in a different room, each left at a different hour, and each carried one curious item. The witness statements are all true; the detective work is yours.
Fill the three deduction boards the way a pencil-and-paper logician would: cross off what a statement rules out, confirm what elimination forces, and let the ✗s corner the ●s. Every case is generated with a constraint solver and machine-verified to have exactly one solution, so a careful chain of inference always closes the case, no guessing, no leaps.
A new case opens every day at midnight Eastern. No app, no signup, play free in your browser, keep a streak, and race the daily leaderboard. More dailies: Cipher, our daily cryptarithm, Links, our hidden-threads puzzle, and Suds, our daily sudoku.
