Catdoku

Catdoku is a cat-themed logic puzzle where you arrange feline pieces across a colorful grid. Each board requires exactly one cat in every row, column, and colored region, with no two cats touching—even diagonally.

How to Play Catdoku

Study the grid and identify cells that cannot contain a cat. Mark these spaces with an X, then compare the remaining possibilities across rows, columns, and colored regions. Place a cat when you have determined a position that satisfies every rule.

Each confirmed placement eliminates other cells in its row, column, region, and neighboring spaces. Continue narrowing the options until every cat has a valid home. Incorrect placements can cost a fish, so use deduction before committing to a cell.

Controls
