Hint: how to open level 20
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 column 1 lies in the Peach region. That cat will use the Peach region, so the other cells of the Peach region can be crossed out. Cross out row 1, column 2; row 1, column 3; row 2, column 2; row 7, column 2 .
- Every open cell of column 7 lies in the Mint region. That cat will use the Mint region, so the other cells of the Mint region can be crossed out. Cross out row 1, column 4; row 1, column 5; row 1, column 6; row 2, column 3; row 2, column 4 and 7 more.
- A cat here would block every remaining cell of the Sage region, so this cell can be crossed out. Cross out row 3, column 5 .
