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.

Hint

Remember you can set the clock parameters in the game options.
