I don't know about this, it's hard for me to say because it's very rare to get big profits in gambling games, especially when I always gamble in sportsbooks.
But for other gambling maybe I will include this as one of my biggest wins by managing to get approximately $ 140 from slots and that is my biggest win by buying $ 3 in a slot game.
I've never had this happen again because apart from rarely playing in slots because I'm always in the sportsbook, I'm also probably too insecure and don't really expect something like this to come again.
