How it works
Three rules and a sharp eye for detail
Every level is a case: a map with rooms, a group of suspects and a missing item. It takes a minute to learn, and there are months of cases to solve.
Read the clues
Every character tells you something about where they are: “She's in the Storage Room”, “He's next to a window”, “It's 2 rows from the Stage”…
Place the suspects
Two pieces never share a row or a column, and every character is in a different room. Each placement rules out possibilities.
Unmask the thief
The thief is whoever shares a room with the stolen item. Put both in their exact cell, press “Validate” and the case is closed.
What's inside
A new mystery every time you open it
100+ levels
One to five stars of difficulty, across four settings: theater, aquarium, library and museum. Play them in any order.
Daily challenge
A different case every day to keep your detective streak going. Missed one? Catch up on the calendar.
Time trial
15 minutes, no hints, as many cases as you can crack. Beat your own record.
Always one solution
Every case is checked by an automatic solver before it's published. You'll never have to guess.
