How to play Shikaku
Fill the grid with rectangles. Each rectangle needs exactly one number, and its area must equal that number.
The rules
6
The 6 marks a six-cell rectangle. This one is 2 × 3.
- One number per rectangle. A rectangle can’t contain a second clue.
- Match the area. Count the cells, not the length of a side.
- Cover the whole grid. No gaps and no overlapping rectangles.
Controls
Desktop
Click and drag between two corners. Right-click a rectangle to remove it.
Mobile
Tap the first and last cell. Press and hold a rectangle to remove it.
A good place to start
Look for a number with only a few possible rectangles.
Try the edges
A clue near a corner or border has fewer directions to grow.
Think in factors
A 12 could be 1 × 12, 2 × 6 or 3 × 4. Rule out shapes that don’t fit.
Look for shared cells
If every shape for a clue covers the same cell, that cell belongs to it.
Check what changed
After drawing a rectangle, look again at the clues beside it.
