Depending on where you look this game is known as either Sudo Ku or Sudoku. You try to get the numbers 1-9 entered into the game grid so that you never repeat a number in a row or duplicate it in each of the 3x3 grids on the screen. The grid starts with a number of pre-filled numbers which are permanent to the playing board. Each level offers exactly one correct solution, so plan carefully. In the Easy mode, the board shows you playing options, to help make sure you understand potential moves. Increase the difficulty to make game play more difficult by removing preset numbers and ultimately eliminate the helper numbers from the board. Whether you're discovering Sudoku for the first time or already know the skills required to master the game, there's a difficulty level for you. Play free for sixty minutes.
