JunoThe Puzzle Purist

“The rules are elegantly minimal and every level has a single solution, so each aha is earned—though Expert’s 'what if' steps feel like guesswork in disguise.”

NicoThe Commuter

“No account, no download, one fresh daily board—perfect for a coffee break, just be ready to tap fast if you want leaderboard bragging rights.”

BeaThe Jam Judge

“A one-idea game done properly: the cat-and-color twist is tiny but deep, and a full solver plus 300 levels show real polish beyond the jam-sized scope.”

How to play

Fill the grid so that every row, every column, and every colored region contains exactly one cat. No two cats may touch, not even diagonally. Click a cell once to mark it as empty, then click again to place a cat.

Tips

• Start with the smallest region, since it has the fewest possible places for a cat.
• Mark cells with an X when a cat rules them out by row, column, region, or diagonal contact.
• If all open cells of a region are in one row or column, that row or column must contain that region's cat.
• On harder levels, try testing a cell mentally to see if it leads to a contradiction.
• Use the hint button if you are stuck, especially on Expert levels that require what-if reasoning.
