Personally if I want to turn a small amount into a quick x profit for fun I do,
If you are really capable of such a feat, then you would be the only guy in the world capable of beating the casinos whenever you want and you could easily be very rich and bankrupt many casinos, because you would be winning constantly and the casinos would be paying you constantly.
10$ into 5-10x I see the most success I have with games like Mines.
I try avoid slot games with low budget, what is your "safest" game for you that you feel lucky on, and have most fun with?
Well, I don't play casino gambling, I prefer sports betting, but in the past when I got involved with casino gambling I played Plinko, so I would choose Plinko as a game where I would have fun, but I didn't win, at the end of the game I was at a loss. So I stopped getting involved with casino gambling and focused on sports betting.
