The board

Step by step

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