Hint: how to open level 40
The first three logical moves on this board, in order. Stop reading after the first one if you only want a nudge.
- Only one cell is left in the Peach region, so the cat must go there. Cat at row 5, column 4.
- Only one cell is left in the Rose region, so the cat must go there. Cat at row 6, column 6.
- A cat here would block every remaining cell of the Mint region, so this cell can be crossed out. Cross out row 3, column 1 .
