Hint: how to open level 21
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 3.
- Every open cell of the Sky 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 5, column 5; row 6, column 5; row 7, column 5 .
- Every open cell of the Sage region lies in column 4. That cat will use column 4, so the other cells of column 4 can be crossed out. Cross out row 6, column 4; row 7, column 4 .
