Sudoku Master

Sudoku Master adds a fun new element to playing Sudoku puzzles. Players will gain experience by completing Sudoku puzzles of different difficulty levels. The objective of Sudoku Master is to advance through the 10 ranking levels by gaining 'XP' (experience) to reach the final rank of Sudoku Master. With each Sudoku you complete you will gain 'XP' (experience) based on the puzzle's difficulty level. You can also earn bonus 'XP' for the speed in which you complete the puzzle and for unlocking various secret achievements. We will be performing weekly updates (correctly, no game progress will ever be lost), we'd appreciate any ideas you have to implement into the game.
