I'd like to answer this particular question, we can't ever tell if it could be sooner or later when we bet I have seen guys here posting their huge wins in high-risk games but it was never mentioned how long they take to win it, in a luck-based games anything and everything can happen, that makes luck based so full of excitement, I have not yet experienced this, but still hoping that it could happen.
Slot and crash games are two high-risk games that can do this, but you'll have to be extremely lucky to experience them.
