Step-by-step solution
- Use the 8 × 8 board shown in the video. Count rows from top to bottom and columns from left to right, starting at 1. Keep any pre-filled pets and check them against the positions below.
- Row 1: confirm the pet in column 7 (region 1 in the answer diagram). Exclude the other squares in this row, column and colour region. In adjacent row 2, columns 6, 7, 8 cannot contain another pet.
- Row 2: confirm the pet in column 4 (region 2 in the answer diagram). Exclude the other squares in this row, column and colour region. In adjacent rows 1 and 3, columns 3, 4, 5 cannot contain another pet.
- Row 3: confirm the pet in column 6 (region 3 in the answer diagram). Exclude the other squares in this row, column and colour region. In adjacent rows 2 and 4, columns 5, 6, 7 cannot contain another pet.
- Row 4: confirm the pet in column 3 (region 4 in the answer diagram). Exclude the other squares in this row, column and colour region. In adjacent rows 3 and 5, columns 2, 3, 4 cannot contain another pet.
- Row 5: confirm the pet in column 1 (region 5 in the answer diagram). Exclude the other squares in this row, column and colour region. In adjacent rows 4 and 6, columns 1, 2 cannot contain another pet.
- Row 6: confirm the pet in column 5 (region 6 in the answer diagram). Exclude the other squares in this row, column and colour region. In adjacent rows 5 and 7, columns 4, 5, 6 cannot contain another pet.
- Row 7: confirm the pet in column 8 (region 7 in the answer diagram). Exclude the other squares in this row, column and colour region. In adjacent rows 6 and 8, columns 7, 8 cannot contain another pet.
- Row 8: confirm the pet in column 2 (region 8 in the answer diagram). Exclude the other squares in this row, column and colour region. In adjacent row 7, columns 1, 2, 3 cannot contain another pet.
- Check the completed board: 8 pets in total, one in every row, column and colour region. No two pets touch, including diagonally. If your result differs, compare row by row with the completed board below.
Useful tips
Final pet positions: R1C7, R2C4, R3C6, R4C3, R5C1, R6C5, R7C8, R8C2.
The written solution checks rows in order; the video shows the elimination sequence. Follow the region shapes as well as row and column rules. For diagonal conflicts, check the row immediately above and below each pet.
