Cat Sudoku

How to play Cat Sudoku

Cat Sudoku is a calm logic puzzle. The board is a grid split into coloured regions, and your job is to place a row of friendly cats so that four simple rules all hold at once:

• One cat in each row.
• One cat in each column.
• One cat in each colour.
• No two cats may touch — not side by side, and not even corner to corner.

Every board has exactly one answer, and you can always reach it by reasoning — you never have to guess. When you place a cat, every square it rules out is gently marked with a faint paw, so the next move is easy to spot.

The three-tap square

There is only one thing to do: tap a square. The first tap places a cat. The second tap leaves a paw-mark — your own “a cat can’t go here” note. The third tap clears it again. No dragging, no typing, and a mistake is never permanent.

Calm by design
