SquareNumberPuzzle

Divide the grid into rectangles.
Each number is the area of its rectangle — one number per box, no gaps, no overlaps.
Drag to draw, and watch the board fill with calm Japanese colors until the last piece clicks into place.

The rules take seconds to learn. Split the whole grid into rectangles (squares count). Every rectangle holds exactly one number, and that number equals how many cells it covers. Cover every cell and you've solved it.
