I just wanted to let you know that there is a new sudoku puzzle game called Andoku available at the Android Market.
To my knowledge it is the only sudoku game for Android that offers sudoku variants such as Sudoku-X, Hypersudoku, Jigsaw Sudoku and combinations thereof.
It has an auto-save function, show some statistics and comes with a total of 3000 sudoku puzzles.
Best of all its free and open source software, see andoku - Google Code
