Modern casino Slots are controlled by computer chips and software, and the winner percentages are pre-programmed into the gaming software.
Casino Slots have Random Number Generators that are ceaselessly generating combinations, even when the slot machine game is not being played.
Running synchronously with the Random Number Generator of the casino slot machine is the pay out per cent.
The pay out % controls just how much the one-armed bandit will pay out, for e.g. the pay out percent might be ninety percent, meaning the slot machine will pay out ninety percent of all the wagers played, … the casino will then get to keep 10 per cent.
This is not to say that each time you bet ten credits you will receive nine in return – where is the fun and thrill in that? Instead, the casino slot machine just will not pay out for a while, and then suddenly fire up a hot streak and you might draw the big pot prize.
The profit %s will tend to vary between the different games and just a few of the most common casinos, for instance Golden Online Casino, which offers a payout of up to ninety-five percentage!
Thus, in essence, the slot machine game takes all the cash played into it and pays it out to a number of chosen winners. The casino only gets to keep a fairly tiny per cent of all the bets placed.
The casino one armed bandit software controls every single part of the machine, from the flashing lights to the rotating of the reels.
When you hit spin on the slot machine game, a combination is generated by the RNG which is linked to the pictures on the reel.
