The board
Step by step
15 deductions lead to the 9 stamps. Each placed stamp also rules out its row, column, touching cells and the rest of its region.
- The mint region can only hold its stamp in row 8, so every other cell in row 8 cannot hold a stamp (7 cells ruled out).
- The peach region has only one cell left: row 7, column 9. Place the stamp there.
- The pink region has only one cell left: row 6, column 5. Place the stamp there.
