Super Sudoku Puzzle Game

Sudoku (数独 sūdoku or "digit-single" in Japanese) is a fun, logic-based, number-placement math puzzle game where the objective is to fill a 9×9 grid with numbers so that each game board column, row, and each of the 3×3 game board sub-grids contain all of the numbers from 1 to 9. The game was featured in French newspapers as early as the 1890's but it wasn't until 1986 did the modern sudoku start to become mainstream.

Gameplay
The puzzle starts off with some of the numbers already filled in for you randomly throughout the game board, however you must use your brain to fill in the rest thereby completing the puzzle. Each number 1 to 9 may only appear once for each 3×3 square, row and column. The number of 9×9 solution grids is 6,670,903,752,021,072,936,960, or approximately 6.67×10^21. Sound tough? It's actually a lot of fun and educational at the same time!

Super Sudoku contains hundreds of puzzles ready for you to solve and new puzzles are added often! There are three difficulty levels for the puzzle types: Easy, Medium and Hard. Once you conquer the easy list, step up and challenge your mind to a workout with a puzzle from a higher category!

Additional features that the Super Sudoku game provides are:
* add numeric notes to any cell on the game board
* add your own custom text notes to any of the puzzles
* see which Sudoku puzzles you've already played
* a game timer so you can see how long you've played each puzzle
* restart any Sudoku puzzle at any time!
* easy to use number input system
* very intuitive user interface
