Gluck has released a Sudoku game for the Nintendo DS:

Removed the '0' number, instead, there is a coloured background on each empty square.
I also added an input method : when you click on a square, it opens a selection window, where you can choose which number to add. You can't change a number which was already on the Sudoku Table.
