Latchkey

The collection

Real-world puzzle games, waiting to be cracked.

Latchkey turns anything into a lock — a photo, a combination, a cipher, a sequence of moves. Open a case file, work the locks, and claim what's inside. No account needed to play.

How it works

Step 1

Open a case file

Browse the collection and pick a game. No account, no install — just start.

Step 2

Work the locks

Every puzzle is a lock: match a photo, crack a code, decipher a riddle, or enter the moves.

Step 3

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.

Photo lock

Arrange real objects to match a hidden target, then take a photo. The lock compares your shot to the key.

Combination lock

A keypad. Work out the code from the clues and enter it — no camera needed.

Directional lock

Enter the right sequence of moves.

Cipher lock

A riddle or code. Type your answer — it’s matched leniently, so don’t sweat exact spelling.

External lock

The puzzle lives on the creator’s own site. You play it there, then come back and the lock opens.
