Su - Do - Ku


Konnichiwa!
Have you ever seen this somewhat complexing type of puzzle being done by salarymen on the trainride to or from home?
It's called Sudoku!
Sudoku was actually created in America, but was refined to its current look in Japan. It was named Sudoku which is an abbreviation of suji wa dokushin ni kagiru (the digits must occur only once).
Though the rules to the game are simple, depending on the level of difficulty of the puzzle you might find yourself stumped for hours.
Let's discuss the rules.


There are 3 basic rules to the game of Sudoku.

1. Each row must have the numbers 1-9 occuring just once.



2. Each column must have the numbers 1-9 occuring just once.












3. The numbers 1-9 must occur just once in each of the 9 sub-boxes of the grid.
