Free · Android 7.0 and later Scan it with your phone’s camera. Scan it with the phone you want it on.
A calm colour logic puzzle, free on both stores. One tap on a phone; on anything else, scan the code for the phone you want it on.
What you get
Every number here is counted out of the build that is on the stores today.
The same board for every player, every day — which is what makes comparing anything worth doing. The calendar is filled to July 2029.
Race a friend live, or send a challenge they answer in their own time.
Place the pieces and the walls; a solver proves it can be done before you share it as a code.
Browse the boards other players have published, and play them.
Eleven languages, colour-blind markings, a light theme, reduced motion and keyboard play.
The journey, Quick Play, the builder and kids mode need neither. The daily puzzle, friends and playing together need an account, because everybody has to be solving the same board.
Before you tap
There are ads between levels, and optional purchases — one that removes those ads, and packs of hints. No chapter is ever behind a payment: the journey opens by being played, and nothing in the game reads what you have bought when it decides what is open.
