CatDoku

CatDoku is a cozy logic puzzle with cute cats! Place the fluffy heroes on the board following three simple rules: one cat per row and column, one cat per color, and no cats in adjacent cells. Easy rules — but the further you go, the trickier the levels get.

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.
