The board

Step by step

11 deductions lead to the 7 stamps. Each placed stamp also rules out its row, column, touching cells and the rest of its region.

1. The peach region has only one cell left: row 7, column 7. 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 can only hold its stamp in column 6, so every other cell in column 6 cannot hold a stamp (3 cells ruled out).
4. The teal region can only hold its stamp in column 1, so every other cell in column 1 cannot hold a stamp (2 cells ruled out).
5. The periwinkle region can only hold its stamp in column 5, so every other cell in column 5 cannot hold a stamp (3 cells ruled out).
6. The amber region has only one cell left: row 2, column 4. Place the stamp there.
7. The pink region has only one cell left: row 6, column 3. Place the stamp there.
8. Row 1 has only one cell left: column 2. Place the stamp there.
9. Row 3 has only one cell left: column 6. Place the stamp there.
10. The periwinkle region has only one cell left: row 5, column 5. Place the stamp there.
11. The teal region has only one cell left: row 4, column 1. Place the stamp there.
