Cat Sudoku: No Ads Puzzles

Find every hidden cat. No ads, no purchases, no tracking. Ever.

Cat Sudoku is a logic puzzle in the Star Battle family. Place one cat in every row, every column and every colored region, and no two cats may touch, not even diagonally. Every puzzle has exactly one solution that you can reach by reasoning alone. You never have to guess.
