The Sudoku is played on a 9 x 9 grid. Within the rows and columns, there are 9 squares (composed of 3 x 3 spaces). Each row, column, and square (9 spaces each) must be completed with the numbers 1 to 9, without repeating any number within the row, column, or square. LofGames has created a very user-friendly interface and many more features for you to enjoy the classic game of SUDOKU.
