An opening for Cedar
Try the grid before opening the walkthrough below. These steps refer to this exact board; rows count down from the top and columns across from the left.
Show the first three deductions
- Look at 4 in row 8, column 9. Only one 1 × 4 rectangle fits without crossing an edge, another clue, or a placed rectangle. Its top-left corner is row 5, column 9.
- Look at 1 in row 9, column 9. Only one 1 × 1 rectangle fits without crossing an edge, another clue, or a placed rectangle. Its top-left corner is row 9, column 9.
- Every cell must be covered. Row 1, column 1 can be reached by only one legal rectangle: the 12 clue, covering 3 × 4 cells.
Each later step assumes that the earlier rectangles have been placed. If your board differs, the in-game explanation works from your current position.
