Mathematics game "Sudoku Japan"



(Pictures above show the example of sudoku problem and its solution)

The first Mathematics game which interesting for me is Sudoku. By the way, Sudoku taken from Japanese words "Suji wa dokushin ni kagiru", meaning "the numbers must be single" or "the numbers must occur only once". This game categorized to logic puzzle based on number placement. How to play this game? it's very simple.
Each Sudoku is made of 81 cells, divided into 9 rows, 9 columns, and 9 boxes. The boxes are 3 cells by 3 cells, and are marked off by the thicker lines. Some of the cells contain a digit, 1 through 9. The object is to fill in the empty cells so that the digits 1 through 9 appear:
• exactly once in each row
• exactly once in each column
• exactly once in each 3 x 3 box
Sudoku helps us strengthening our left brain. If you want to try this challenge, just click this link.
