How to Play

Shikaku presents a grid with numbered cells scattered inside. You must partition the grid into rectangles so that each rectangle contains exactly one number, and that number equals the area of the rectangle.

For example, a cell with a 4 must belong to a rectangle covering exactly four cells. The rectangles cannot overlap and must cover the entire grid.

Controls

Click and drag to draw rectangle borders. Some versions let you click cells to assign them to a rectangle.

Scoring

Completion time and the number of attempts determine your rank.
