Personally if I want to turn a small amount into a quick x profit for fun I do,
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?
dice by a big margin to any other game.
i have been playing dice for years and as long as i don't get greedy when i'm having a good run, it's the game i won the most money on and is the "safest" for me.
They're all 3 the same thing if you know anything about casino originals, the animation is the only thing different. I personally have had the most success on dice type games though if I need a boost.
the only other difference besides the animation/design is the max payout for each original.
dice have 9900x max payout (some casinos limit it to 99x), i have seen limbo pay up to 1000000x, but not sure about mines as i don't like it or play it often to know.
