The games on this site require the Java (tm) runtime environment from Sun Microsystems. If you don't have this installed, you can get it for free at http://java.com.

Simply click on the "Sudoku Puzzles" link on the left. The selected puzzle should start up shortly.

In the game of Sudoku (or Su Doku) you're presented with a 9x9 grid which is subdivided into nine 3x3 grids. When the puzzle is solved, each cell in the grid will contain a single digit, 1 through 9.

In he beginning, some numbers are shown, but the rest are hidden. The object of the game is to fill in the missing numbers so that each 3x3 cell, each row, and each column in the grid contains each of the digits 1 through 9.

There is only one possible soltion for each puzzle, so don't try to guess the numbers. Use logic and the process of elimination to determine where each number goes.
