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.
