How to play
- Some puzzles start with one cat already placed to help you out.
- Pick a size, or Random for a different board size (7 to 12) every puzzle.
- Put exactly one cat in every row, every column and every coloured patch.
- Cats can't touch, not even corner to corner.
- Tap a square to mark it ✕ (drag to mark several). Double-tap, or switch to Cat, to place a cat.
- A wrong cat costs a heart and leaves a red ✕. Lose all three and the round is over.
- Keyboard: arrows move, Space marks, Enter places a cat, Z undoes.
Every puzzle has exactly one solution, so you never need to guess.
