The board

Step by step

13 deductions lead to the 9 stamps. Each placed stamp also rules out its row, column, touching cells and the rest of its region.

1. The rose region has only one cell left: row 1, column 6. Place the stamp there.
2. The amber region can only hold its stamp in row 2, so every other cell in row 2 cannot hold a stamp (3 cells ruled out).
3. The green region has only one cell left: row 3, column 9. Place the stamp there.
4. The teal region and the periwinkle region must all put their stamps in rows 4 and 5, so every other cell in rows 4 and 5 cannot hold a stamp (8 cells ruled out).
5. The teal region and the mint region must all put their stamps in columns 7 and 8, so every other cell in columns 7 and 8 cannot hold a stamp (4 cells ruled out).
6. The pink region has only one cell left: row 6, column 5. Place the stamp there.
7. Column 7 has only one cell left: row 4. Place the stamp there.
8. The periwinkle region has only one cell left: row 5, column 2. Place the stamp there.
9. The peach region can only hold its stamp in column 3, so every other cell in column 3 cannot hold a stamp (2 cells ruled out).
10. The amber region has only one cell left: row 2, column 1. Place the stamp there.
11. Row 9 has only one cell left: column 4. Place the stamp there.
12. The peach region has only one cell left: row 7, column 3. Place the stamp there.
13. The mint region has only one cell left: row 8, column 8. Place the stamp there.
