8.4 is the perfect place to play all things sudoku. This online version allows you to play the classic game as a novice or an expert as you complete sudoku puzzles of all different difficulties. You can set your difficulty level to one of four different levels to challenge you no matter your experience playing the game.

If you have never played sudoku before then it is a logic-based number game in which you must complete the grids by filling them in a formation that contains all of the required numbers from 1 to 9 in each row, column and box. If duplicate numbers are entered then they will highlight in red to help you. Good luck!
