Sudoku is a logic puzzle game that some people claim it was invented in the USA  with the name number place. However there are reports that it was originally in a french paper in 1895 and there are also evidence showing that a similar game was played during the 10th century.

Back to our topic now which is how to play sudoku. The most common form of sudoku puzzles is the one that we use here for our flash sudoku game. That means that it's a square grid with nine rows and nine columns and 81 small square boxes in total. This grid contains nine smaller grids  that are usually called regions or blocks. Some of the squares inside the grid contain numbers (1-9) that  are called givens (note that the numbers may be replaced by letters, symbols, pictures or anything you like). Your aim is to fill the remaining eampty square boxes with the numbers (1-9) so that each column, row and region doesn't contain the same number more than once.

As you can see the rules are simple, however to get a better understanding about the game of sudoku the best way is to start playing. Oh and don't forget, patience and logic are your best friends.
