I have played a lot of slots online and in casinos. I even owned a slot machine to see how they work.
I found out there are multiple payout settings inside a machine. So they can make it easier to win or harder to win. The best slots to play are by the casino entrance. as they want people to see others winning to draw more people in. As for the online casinos, it is all software driven so we don’t know how they work. They must have a menu for every online slot machine to set payouts. What else can they set?
I seem to see a trend and it must be my bad luck or good luck at times. I will play a random machine. I win a good pot then the machine gives me nothing. The record for no wins is almost 60 spins at OLG slots online. I won $100.00 and then it gave not one win for almost 60 spins. How does this happen? Are they tracking you online unlike real casinos where they have no clue who you are from machine to machine?
Then you get these machines that say 96.9% payouts. I think this is based on winning slot spins and not actual money. I could be wrong but I have been on a machine that is $0.10 spins and goes through $10.00 without hitting a bonus or winning. A lot of machines like to give you your bet back or less than what it costs you to spin.
You need to know when to walk away from the slots when you are up and cash out often.
Good Luck
