Do you pull games out of circulation? I looked back to May and a game I played was never played again.
Unless someone (like you) who had saved the game returns to it, the probability of that game number coming up again at random is low.
@hobnailboots, there are more solitaire shuffles than atoms on earth, so we have to do something to ensure that lots of people play the same shuffles. Generally, each hour we have a sequence of shuffles that we steer everyone to, but you can play, or skip past, all of them and end up off the path in random territory where you might never see someone else play the same one.
