I keep hearing about games to play on your reader, but I have no idea how to make it work.
I would really like to play Sudoku on mine as I like to alternate games between reading on long flights. (Geez flying is boring and leg aching

)
I usually have a book and a Nintendo DS for this purpose. Wouldn't it be great to have both on one device? Lots of books and Sudoku.
If anyone knows how to make Sudoku on a PRS-900 I would like to hear from you. I am a real learner as I have had my first reader less than a month.

in advance.
