I'll think about adding a timer!
Becca, at the moment it's infinite. I added over 1,000 covers which are picked at random :)

Glad you like the game :)

improbably = improbable
probably = probably (I think :) )

You could just calculate the probability. All you need is the chance to win the lottery and the number of participants playing each turn. Do not make the error of looking at how improbably a *single* person winning is, but how probably *any one person* winning each round is. And even when the chances at winning lottery are very small, in almost every turn -- at least with German lottery -- *someone* wins. So the one is likely, the other is unlikely. So -- how likely is it that *any one person* wins twice? How likely is thrice?
