The rules of the game

Sudoku is a japanese mind game. You must find the way to place digits from 1 to 9 on a 9x9 grid. At the begining of the game, a few digits are given, and there is only one way to fill the grid correctly. Each digit must be placed in order to respect each of the following rules:

- The same digit can not be repeated in the same row.
- The same digit can not be repeated in the same column.
- The same digit can not be repeated in the same 3x3 square.

Traditionally, Sudoku is a solitary game. But on this app, it's a game for two players. Each player plays after the other until the grid is full. At the end, the player with the smallest count of errors wins the game.
