Make a jigsaw with a secret message
Upload a picture, write a hidden message and share the link. Whoever finishes the puzzle sees the message and can copy it.
The message stays on our server
It isn't in the page, the link or the picture. It's only sent after the puzzle is finished.
Made for mystery caches and breakouts
Put final coordinates, a lock code or the next clue in the message.
No account to solve
Solvers just open the link. Progress is saved on their device, so they can come back later.
Create your puzzle
Only upload images you own or have rights to use.
How safe is the message?
The message is never in the page, the link or the picture, so peeking at the page source doesn't reveal it. Our server only releases it after a solve that took a realistic amount of time. It is a puzzle lock, not a vault: a determined programmer could still fake a solve, so don't use it to protect anything valuable.
