About Cat Sudoku

Cat Sudoku is a free logic puzzle you play in the browser. Place one cat in every row, every column, and every colored region, and keep the cats from touching, even diagonally. The rules are the queens rules, drawn here with original cat art.

Puzzles are generated on your device and checked so each one has a single solution. There is a daily puzzle, an unlimited practice mode, and a way to paint a grid and share it. Nothing on this site requires an account.

The drawings, puzzles, and writing are made for this site. Cat Sudoku is not affiliated with any other cat puzzle publisher. Read the rules, the privacy notes, or go back and play.
