About game
Logic puzzles gain a fresh charm when you replace numbers with adorable feline friends. CatDoku transforms the classic судоку format into a relaxing brain teaser that challenges your spatial reasoning while keeping things lighthearted. Every board requires you to place a cat strategically so each row and column contains exactly one fluffy companion. You must also respect the color zones, ensuring that no two cats share the same hue. Things get complicated when you realize that nearby cells must remain empty, forcing you to think several steps ahead to avoid overcrowding. Solving these puzzles boosts your IQ as you navigate increasingly complex grids. You can tackle over 100 levels without any stress or time limits holding you back. Play CatDoku directly in your browser now since no download is needed to start your pet puzzle journey.
How to play
The goal is to place cats on the board so that all three rules are satisfied.
CatDoku Rules:
🐾 1 cat per row and column — exactly one cat in each row and each column.
🐾 1 cat per color — exactly one cat in each colored zone.
🐾 Cats are not adjacent — no two cats can be in neighboring cells, including diagonally.
How to play:
Tap an empty cell to place a cat.
Tap it again to remove it.
Arrange all the cats so that no rule is broken.
Tips:
• Look for rows, columns, and colored zones with the fewest empty cells left — start with those.
• Once you place a cat, mentally cross out its neighboring cells, as well as its entire row, column, and color.
• If you're unsure — use the hint, it will reveal a correct position.
Clear all 100+ levels and become a CatDoku master!
