Sudoku Original

Controls:
The rules to sudoku are very simple: fill in the grid so that every row, every column, and every 3x3 box contains the digits 1 though 9. There is nothing more to it!

You can use the keyboard to select squares using the arrow keys and then type in the digit you want to place. 0 will set the square to empty. Or you can simply fill in the grid by selecting squares with the mouse and pick digits from the small grid that pops up.

Description:
Just like the original Sudoku game! Place the numbers in the slots and solve the puzzle. Extremely challenging game!
