Shikaku

Shikaku (also known as Rectangles) is a logic puzzle with simple rules and challenging solutions.

The rules are simple. You have to divide the grid into rectangular and square pieces such that each piece contains exactly one number, and that number represents the area of the rectangle.

Click and drag to draw a rectangle. To remove lines use the right mouse button or hold the Ctrl or the Shift key.
