The chance of winning casino slot machines is even lower than at roulette, especially at slots with progressive jackpots where the chance of winning falls below 40%.

Of course,

there are times when the size of the jackpot makes the mathematical expectation of winning a positive amount, but few people have the amount of money and human resources to cover all the slot machines that form the jackpot and play them until the jackpot is won.

Among the slot machines you can only stop at the video poker, in which the chance of winning is close to 50%, where you can really win at the casino if you play the right game. But I want to pay attention to the fact that you can win video poker not in every casino and not on all machines.
