Shikaku Land — Number Logic

Shikaku is the classic Japanese logic puzzle, reimagined clean and calm.

The rules are simple: every number is the area of a rectangle. Split the whole grid into rectangles so each one holds exactly one number — no gaps, no overlaps. Easy to learn, deeply satisfying to master.
