In Sudoku, you get to fill a 3X3 grid with the numbers 1 to 9; these numbers must never be repeated. The grids are joined to form a larger 9X9 grid, and the columns and rows of this grid and filled with the numbers 1 to 9; in this case also, the numbers must never be repeated.

This is a great game with an old fashioned feel and it will make you happy to know that it is a free online Sudoku game which is designed to take you down memory lane.
