Explanation of gameplay:

Number of independence is a math intellectual puzzle game that originated in the end of the 18th century. Later, it developed in the United States and was able to carry forward the light in Japan. The puzzle is a square shape of the Jiugong grid (that is, the 3 square width X3 grid), and each grid is subdivided into a Jiugong grid. In each small Jiugong grid, fill in the numbers of 1 to 9 respectively, so that the number of each column and each line of the entire Jiugong grid will not be repeated. The logic of the single gameplay is simple, and the number of numbers is ever -changing. Many educators believe that counting independence is a good way to exercise brains. In addition, the number of independent games can set different difficulty levels according to the age and ability level of children.
