Play Shikaku Online Free
Shikaku is the rectangle-division puzzle at its most elegant: a grid contains a handful of numbers, and you must partition the entire board into rectangles so that each number sits inside a rectangle made of exactly that many cells. A 2 means a 1x2 or 2x1 rectangle, a 6 can be 2x3 or 3x2 or 1x6, and every cell must belong to exactly one rectangle.

Tips & Strategies
- Start with the largest numbers - their possible rectangles are the most constrained and often force nearby lines.
- A 1 always occupies a single cell by itself; mark it immediately to stop neighboring rectangles from swallowing it.
- Look for rows or columns where a rectangle of a certain width is the only possible fit.
