How to play Cat Sudoku
Cat Sudoku is a logic puzzle. The board is a grid split into coloured regions, and you place cats so that four 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 corner to corner.
Every board has exactly one answer, and you can always reach it by reasoning, so you never have to guess. When you place a cat, every square it rules out is marked with a faint paw.
The three-tap square
You only tap squares. 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. There is no dragging or typing.
Hints and clearing the board
There is no timer, and you cannot lose. Stuck? Press Hint to drop one correct cat into place, or Clear board to try the same puzzle fresh. If you prefer numbers, there is a large-print Sudoku too.
