Shape positions
Rows and columns below start at 1, from the top left.
- Shape A: top-left row 1, column 1; 3 rows × 3 columns (9 cells).
- Shape B: top-left row 1, column 4; 3 rows × 2 columns (6 cells).
- Shape C: top-left row 1, column 6; 3 rows × 3 columns (9 cells).
- Shape D: top-left row 4, column 1; 1 rows × 8 columns (8 cells).
- Shape E: top-left row 5, column 1; 2 rows × 4 columns (8 cells).
- Shape F: top-left row 5, column 5; 4 rows × 2 columns (8 cells).
- Shape G: top-left row 5, column 7; 4 rows × 2 columns (8 cells).
- Shape H: top-left row 7, column 1; 2 rows × 4 columns (8 cells).
Why it works
The 8 × 8 board has eight shapes. Across rows 1–3, A is a 3 × 3 square on the left, B is a 3 × 2 rectangle in the centre and C is a 3 × 3 square on the right. Shape D fills row 4 from edge to edge. E and H divide the lower-left block, while F and G are the two tall rectangles on the lower right. Their areas total 64 cells with no gaps or overlaps. The original hidden clues were not recorded.
