What do you guys think? Is it pure probability catching up with you, or do casinos tweak the games to make sure you lose eventually?
All casinos are meant to have advantage over gamblers and so as slots. Even if you get lucky early game, the more you play to it the more there is the chance the slot will get back your winnings.
I've experienced it many times and they all work that way. The same work on other games such as roullete or plinko where gamblers will always lose to them.
