In slot game, it's very possible to turn $0.2 to $10k which is really a massive jackpot but it very difficult to have such a win, only in rare occasions.
It does happens only on rare occassions and few gamblers. While the possibility is truly there but, it won't happen for the majority of us. Someone can make that penny into a hundred and then eventually losses it because of not being enough. And I can think that those who were to make thousands from cents, maybe not all of them happily cashed out all that they've won. In sports betting, I've seen many times other bettors won thousands but of course not with that wagering amount. It won't be enough and I think even a x1000 won't hit $10k, it's just 200 bucks.
