Catnap · free daily Queens-style logic puzzle
Catnap is a free Queens-style logic puzzle — the same rules as LinkedIn Queens, Star Battle, and Meowdoku. Place one sleeping cat in every row, every column, and every color region, with no two cats touching, not even diagonally. Every board has a single solution you can reach by pure deduction — no guessing.
There's a fresh daily puzzle the whole world shares, ranked by solve time, plus an unlimited ladder of practice levels and a growing daily archive of past boards with hints and answers. New here? Read the rules or pick up some Queens solving tips. No app, no ads gating your next puzzle, no sign-up to play.
Everyone in the world gets the same board each day, and the leaderboard ranks solves by time. If you're stuck, a hint shows you the deduction you missed instead of giving away the answer — every board is solvable by pure logic, no guessing required.
Yes. The daily board and the level ladder are free, in your browser, with no download and no sign-up required to play.

Yes — it's the same family of logic puzzle. Place exactly one piece per row, column, and color region, with no two touching (including diagonally).

Both. Beyond the one shared daily board, the level ladder serves an unlimited run of boards that ramp up the logic techniques one at a time, and the daily archive keeps every past board with its hints and answer.
Yes — the level ladder serves a sequence of boards that ramp up the logic techniques one at a time, so there's always another to solve.
