Rules and play
Shikaku of the Day Game Rules
Cover the whole grid with rectangles and squares. Each region contains exactly one number. Area must match the clue: a 6 may be 1×6, 2×3, 3×2, or 6×1, but edges and other clues decide which survive. A 4 might be a 1×4 strip or a 2×2. Overlaps, two clues in one box, or a leftover cell fail. Choose a difficulty, then drag corner to corner.
- Divide the Shikaku of the Day grid into non-overlapping rectangles.
- Each rectangle holds exactly one number equal to its area.
- Every cell must belong to a region.
- Play Easy through Master; a shape that blocks another clue is illegal.
