Modern casino Slots are controlled by computer chips and software, and the winning percentages are preprogrammed into the computer software.
Casino slot machines have Random # Generators that are continually generating combos, even when the slot machine game is not being played.
Running concurrently with the Random Number Generator of the casino slot machine game is the payout percentage.
The payout % controls just how much the one-armed bandit will payout, for example the pay per cent may be 90%, meaning the slot machine game will payout 90% of all the stakes played, … the casino will then get to keep ten percent.
This doesn’t imply that every time you bet ten credits you will receive 9 in return – where’s the fun … exhilaration in that? Instead, the casino slot machine game will not pay out for a while, and then suddenly fire up a hot streak and you might hit a big top prize.
The payout %s will most likely vary between the assorted games and some of the extremely common casinos, for example Golden Online Casino, which tenders a pay out of up to ninety five per cent!
This means that, in essence, the one-armed bandit takes all the $$$$$ played into it and pays it out to a couple of privileged winners. The casino only gets to keep a basically small percentage of all the stakes allocated.
The casino slot machine software controls each and every part of the machine, from the flashing lights to the rotating of the reels.
When you hit spin on the slot machine, a combination is put together by the RNG which relates to the pictures on the reel.
