Games can be played in two modes, Sudoku Classic which is a 9x9 grid and which has four levels of difficulty, or Sudoku Junior which is a 4x4 grid. Games are timed and the player is awarded points for their completion. The game supports multiple player names so a group of players can compete for top score on the high score table. The Classic puzzles can be printed, e-mailed, or changed to use letters rather than numbers. There is also an option which allows the player to manually enter puzzles and either play them or have the program solve them automatically.
