ZuDoKu 4+

This app is a new kind of the classic Sudoku game. With this app, users can choose three different types of Sudoku games to play:

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 in each game to keep the games challenging.
2. New Sudoku 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, in each game, the app will notify users if they select an item (number, letter or figure) for 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. This ensures users will be able to complete every game they play.

Furthermore, to make games even 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. Finally, after a game is completed, the app will display game statistics  and compare that to any of your past best game results for the same game level. This aids you to gauge your progress in improving game solving skills.
