Shikaku is played on a rectangular grid where some of the squares are numbered.
The objective is 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.
Tip: On smaller puzzles odd numbered cells are easier to figure out placements for because they have to be only one column across in one dimension, though on larger puzzles odd numbers could be three rows or columns wide.
