Accuso
A new logic mystery every day
Every morning, a new crime, from country manors to night trains. Five suspects, one culprit, and a page of notes from the scene. Work out who was where, carrying what, and when, then make your accusation.

Never a guess
Every case is checked before it reaches you: exactly one answer, reachable by reasoning alone. If you’re sure, you’re right.
Three cases a day
Easy, medium and hard, with four, five or six suspects. Name who on easy; who and where on medium; who, where and with what on hard.
A nudge, not the answer
Stuck? A hint tells you which suspect you can work out next and exactly which notes to use.
Share the solve, not the spoiler
A result card shows how your solve went without giving away who did it.
Your notebook
Every case has room for your own working under the clues. It stays on your phone and is never shared.
One payment, no subscription
Free to play with ads. Premium removes them, gives unlimited hints, and opens every past case.
