Funny question because let's say I tell you that it's 100. Will you believe me? Will you feel confident in your skill when after 100 bets in dice or slots you are in profit? Will you tell everyone that you're a good player after that?
If I tell you that it's a million bets, will you play long enough to try it?
This thread cannot answer your question and even if it does, you probably won't do anything with that knowledge.
