iRectangles is yet another puzzle app for the iPhone. This app is based on the nikoli puzzle sikaku. For the puzzle, you are given a grid of arbitrary size. Some of the individual squares in the grid have numbers in them. These numbers correspond to the number of squares in a rectangle. The object of the puzzle is to section off the grid into a collection of rectangles such that each rectangle has a single number in it that is the rectangle’s area. There should be no spaces left over in the grid.
I’ve found a couple sites, just by googling, that has some examples of the puzzle that you can try. And, of course, there is always the iPhone app.
This is a really cool game. Its not that hard but a lot of fun. On the iphone application you compete on time so its fun
Never paid much attention to Sikaku, but the more I look at it and find more Sikaru puzzles, the more I like them. Thanks for pointing this out!
