Daily Whodunit is a free puzzle site with a new murder mystery every day. Each case is a puzzle you can play in your browser or print and solve with a pencil.
How it works
Our first format is Murder Mystery Sudoku. Every day a victim is found dead somewhere: a country manor, a night train, a theatre, a ski lodge. Six people had a motive. To find the killer you solve a classic 9×9 sudoku, then read three marked evidence cells. Their numbers point to the suspect, the weapon and the room.
Cases get harder through the week. Monday and Tuesday are easy, Wednesday and Thursday are medium, Friday and Saturday are hard, and Sunday is a tricky one to finish the week. Every puzzle is checked by computer before it is published, so each grid has exactly one solution and the evidence always points to one killer.
Why we made it
Sudoku is one of the most loved puzzles in the world, and murder mysteries are having a moment. We wanted something that gives a daily sudoku a reason to exist beyond the grid: a small story, a little suspense, and a satisfying moment when you name the culprit.
Daily Whodunit is made by an independent puzzle maker and book publisher. It is free to play and is supported by advertising.
What is coming next
Sudoku is only the first format. We plan to add more kinds of mystery puzzles over time, such as logic grids, ciphers and crosswords, along with recommendations for mystery books, films and games.
