Luck does exist. I've experienced it myself, winning a large multiplier on a bonanza game, more than 100 times my initial deposit. You're lucky to experience this, because not everyone wins big. Perhaps it's just not their time, and luck will be on their side later and give them a big win to enjoy. I personally enjoy my winnings by buying motorcycle spare parts, as that's one of my hobbies.
Everyone wants big wins, but not everyone is lucky at the same time.
