About Purr Grid
Purr Grid is an independent SailToWorld browser game. Its region boards are generated by this site, with a solver checking that each has exactly one solution. It is not an official Meowdoku product, and it does not reproduce that app’s numbered levels.
Built around a complete puzzle
Play immediately, use marks and undo, and return to the same saved board in this browser. The daily puzzle uses a UTC date so players receive the same board. There are no account or payment requirements.
