Hi. I've been playing Blind Gamers Sudoku for a while and mastered all of
its difficulty levels, so I wanted to find something more challenging. I
found The Ultimate Soundoku on audiogames.net and downloaded it, but I
noticed one feature I wish it had: the ability to add pencil marks to empty
cells like in BG Sudoku. This helped me remember what values I ruled out for
each one. Does anyone here play The Ultimate Soundoku? If so, how do you
keep track of what can go in each cell without pencil marks? I would really
appreciate any help.
