Hint: how to open level 42
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 Lilac region, so the cat must go there. Cat at row 2, column 1.
- Only one cell is left in the Mint region, so the cat must go there. Cat at row 3, column 6.
- Every open cell of the Peach region lies in column 5. That cat will use column 5, so the other cells of column 5 can be crossed out. Cross out row 1, column 5; row 7, column 5; row 8, column 5 .
