This app is a new kind of the classic Sudoku game. With this app, users can choose three different types of SudoKu games: 1. The classic SudoKu games that use numbers 1 to 9. 2. New SuDoKu games that use interesting figures instead of numbers. A different set of figures are used for each game to keep the games challenging. 2. New SyDoKu games that use letters (A to I) instead of numbers. Added to the above, users may choose different game levels to challenge their logic and analytic skills. Moreover, for each game, the app will notify users if they select an item (number, letter or figure) for a location that is in conflict with the same item that is already set in the same row, column or quadrant with respect to that location. Finally, to make games more interesting, users may choose if there is a time limit or no time limit set for each game. Also, you may turn-on/off sound effects that are used to alert users when they have completed one row, one column, one quadrant, the entire game or time has expired. Moreover, after a game ended the app will display the game statistics and their comparison to any past best game results for the current game level.
