Quick Reminder: Shikaku Rules

Shikaku is a captivating Japanese spatial logic puzzle. The goal is to divide an entire grid into rectangles and squares by following three fundamental rules:

  • One number per rectangle: each rectangle must contain
    exactly one number.
  • Area must match: the number tells you how many cells the rectangle must cover (its area).
  • Full coverage: every cell in the grid must belong to a rectangle — no overlaps, no empty cells.

Also Known As: Sikaku, Divide by Box or Rectangles

Shikaku goes by several names around the world. Whether you’re searching for free printable Sikaku, a Divide by Box worksheet, or simply rectangle logic puzzle PDFs — the rules are always the same. Our puzzle packs cover all these names so you always find what you’re looking for.
