I have completed 51 games now, all "Hard", and I am certain some have been repeats. How does this App generate games? Is there a finite number that get cycled through? If so, how many? Or is there some type of number generator that would make the possible number of individual games almost infinite?

It would be really nice to assign an ID to each game that could be stored; perhaps even be able to request a game ala Web Sudoku.

Thanks

I can't assign an ID to each game because each one is unique. It's virtually impossible for you to have played the same game twice.

The number of possible games is not infinite, but in Sudoku Book it's well in the millions... in each level.

If you want to save games, you can use the share button and store them in your queue. But the queue is limited to 100 games.
