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.

A CHALLENGE THAT KEEPS CLIMBING • 50 levels, each one harder than the last • A new technique every few levels: line locks, squeezes, color groups and what-if chains • Master difficulty from level 30, on grids up to 9×9

A NEW PUZZLE EVERY DAY • One daily board, the same for everyone: gentle on Monday, tough by the weekend • Keep your streak going and share your time without spoiling the puzzle

NOTHING IN YOUR WAY • No ads, no in-app purchases, no coins, no energy, no paywalls • No accounts and no data collection (see the App Privacy label) • Plays completely offline • Colorblind mode that labels every region • Optional auto-mark that crosses out squares for you
