>>Sample problems of Shikaku puzzle


  1. Divide the grid into rectangles with the numbers in the cells.
  2. Each rectangle is to contain only one number showing the number of cells in the rectangle.


Shikaku is another original Nikoli puzzle, which provides a special sense of solving while complying with a very simple rule. Beginners may try starting with a guess, but will quickly see that the fun is searching for rectangles by logic. Shikaku is also a great math trainer for kids. While playing the game they learn multiplication such as a 12 can be 1x12, 2x6 or 3x4. And if you get stuck, look at the puzzle from a distance and you will soon find the next rectangle.
