Catdoku Queens: Logic Puzzle

Catdoku Queens is the Queens logic puzzle — with cats. Place one cat in every row, every column and every colour region, and never let two cats touch, not even diagonally. Also known as Star Battle or Two Not Touch.

NEVER A LUCKY GUESS
Every level has exactly one solution and can be solved step by step by reasoning alone. Stuck? There is always something to find.

HINTS THAT EXPLAIN
A hint shows where the next cat goes and names the row, column or region that forced it. Hints are never sold — new ones arrive as you play.

AN ENDLESS ROAD OF PUZZLES
Chapters from gentle 5×5 boards up to 12×12 monsters, each ending with a boss that fights back if you dawdle.

CALM RUNS AND A DAILY PUZZLE
Play with no clock and nothing at stake, or solve today's puzzle — the same board for everyone. Fully offline, no account.

FAIR ADS
A banner on the map, never on a puzzle; a full-screen ad about every third level; rewarded videos only if you choose. One purchase removes the banner and full-screen ads for good.

• Catdoku is now Catdoku Queens — the same no-guess cat puzzle, now in 13 languages.
• Bosses fight back: take too long or place a wrong cat and the boss takes one back. Beat it before it wakes for bonus fish.
• A clock bar that drains from both ends, so you can feel the time without reading it.
• Placing a cat now sends a wave through every square it rules out.
