How it works
Open a case file
Browse the collection and pick a game. No account, no install — just start.
Work the locks
Every puzzle is a lock: match a photo, crack a code, decipher a riddle, or enter the moves.
Claim what's inside
Open a lock and its reward drops into your bag. Clear them all to close the case.
The kinds of lock
Creators build each puzzle from one of these — some you solve on your phone, one with your hands.
Arrange real objects to match a hidden target, then take a photo. The lock compares your shot to the key.
A keypad. Work out the code from the clues and enter it — no camera needed.
Enter the right sequence of moves.
A riddle or code. Type your answer — it’s matched leniently, so don’t sweat exact spelling.
The puzzle lives on the creator’s own site. You play it there, then come back and the lock opens.
