About Whodunnit Daily

Whodunnit Daily is a free daily logic deduction game. Each day you meet a small set of suspects, each making a single statement. Exactly one is guilty — and the guilty one lies, while every innocent tells the truth. Your job is to reason out who must be guilty.

What makes it different

There's no luck and no guessing. Every puzzle is built so the clues admit exactly one consistent culprit. You can always justify your next move by pure logic. The game even checks this at load time: if any puzzle were not uniquely solvable, a warning banner would appear.

How to play

Read the statements, hypothesize a culprit, mark each statement true or false, and keep the only suspect for whom the rules hold. New to it? Start with the how to play tutorial, then try today's puzzle. The full reasoning for the current case is on the today's answer page.

Daily & Unlimited

Play one fresh puzzle a day in Daily mode (everyone gets the same case), or switch to Unlimited for back-to-back puzzles. The game tracks your streak and stats locally on your device.
