Hint: how to open level 45
The first three logical moves on this board, in order. Stop reading after the first one if you only want a nudge.
- Every open cell of the Peach region lies in row 5. That cat will use row 5, so the other cells of row 5 can be crossed out. Cross out row 5, column 1; row 5, column 2; row 5, column 3; row 5, column 4; row 5, column 7 and 2 more.
- Only one cell is left in the Coral region, so the cat must go there. Cat at row 6, column 2.
- Every open cell of the Sky region lies in column 1. That cat will use column 1, so the other cells of column 1 can be crossed out. Cross out row 1, column 1; row 2, column 1; row 3, column 1; row 4, column 1 .
