This Sudoku has four rules

                1.  Every row must have all 9 different digits.

                2.  Every column must have all 9 different digits.

                3.  Same rows on the three boxes which positioned north and south must have all 9 different digits. (Shaped like Chinese character (San, three))

                4.  Same columns on the three boxes which positioned east and west must have all 9 different digits. (Shaped like Chinese character (chuan, river))

 

An example in a simple diagram below can explain rules 3 and 4.  The shaded areas on the left diagram are for rule number 3 and on the right diagram are for rule number 4.  They all have nine such arrangements.

 

這題比較不同.是個包含兩組九個中國字的數字魔術方塊.它們的規則如下:

每一行必須有九個不同數.

每一列必須有九個不同數.

每一列三個九宮上,同位置的三個行必須有九個不同數.

每一行三個九宮上,同位置的三個列必須有九個不同數.

後兩個規則請參考附圖中深色的地帶.左是三右是川.圖中只是九個中的一個例子.因為有三有川就叫三川數字魔術方塊.
