Level 23 guide: Brazil (hard)
Rhythm, rainforest and the beautiful game. A 9×9 board. Colors are named in the steps below, and rows and columns are counted from the top left starting at 1. This guide spoils the solution, so try the level first.
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 green region has only one cell left: row 3, column 6. Place the stamp there.
- The mint region can only hold its stamp in column 7, so every other cell in column 7 cannot hold a stamp (4 cells ruled out).
- Row 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).
- The amber region and the teal region must all put their stamps in rows 2 and 4, so every other cell in rows 2 and 4 cannot hold a stamp (3 cells ruled out).
- The mint region and the stone region must all put their stamps in rows 8 and 9, so every other cell in rows 8 and 9 cannot hold a stamp (10 cells ruled out).
- The peach region can only hold its stamp in row 7, so every other cell in row 7 cannot hold a stamp (5 cells ruled out).
