Shikaku is a pure logic puzzle from Japan, also known as Rectangles or Divide by Squares. The grid holds a scattering of numbers. Your job is to cut the whole grid into rectangles so that each rectangle contains exactly one number, and that number is the rectangle's area. No guessing, ever. Every puzzle has exactly one solution and it can always be reached by reasoning alone. There are no lives and no mistake counter: a rectangle that breaks the rules is simply refused by the board, so you are free to try things.
