Slots are for losers...Why play them ? On top of being crippled by a house edge the slot also keeps a portion of your cash...Unless you are playing in a land casino where other people that wagered before you would already have accumulated in the slot if you play online than other people don't affect the slots. Even if it did it would mean that the other 10 people playing the same slot as you might reap the big win while you are unaware and still waiting for it to pay out
even if it did payout big the money it keeps from your wagers and the house edge will always put you behind in the end.
I recommend video poker with good paytables rather than slots any DAY! a jacks or better 9/6 paytable pays over 99% now you don't wanna know what slots pay.
The casino is obligated by law to use RNG(random number generator) for their slots and I have to say its the only thing keeping people with poor math skills spinning.However the casino can keep as much from you as they want and they can charge you any hidden commission they want legally.
The more frequently it pays the less chances a person has of winning a jackpot and casinos know this also which is why new slots have more pay lines because this increases the frequency of pay.
Just don't invest hard earned money in a slot or your blackjack winnings either.Nobody knows for certain if slots unload at specific times but everyone knows they have a high house edge and that alone is more than anough reason not to play them.
