Modern casino slot machines are controlled by computer chips and software, and the win percentages are preprogrammed into the software.
Casino slot machine games have Random # Generators which are constantly generating combos, even when the game is not active.
Running jointly with the Random Number Generator of the casino slot machine game is the pay out rate percent.
The payout per cent controls just how much the one-armed bandit will payout, for eg the pay % might be 90%, which means the slot game will pay out ninety percent of all the wagers played, … the casino gets to keep 10 per cent.
This doesn’t imply that each and every time you bet 10 credits you will receive 9 in return – where’s the fun and thrill in that? Instead, the casino one arm bandit will not pay out for a while, and then suddenly fire up a hot streak and you might catch the big pot prize.
The pay out percentages will definitely vary between the alternate games and a couple of the notably common casinos, e.g. Golden Online Casino, which hands out a payout of up to 95 percentage!
So, in essence, the one-armed bandit takes all the $$$$$ played into it and pays it out to some privileged winners. The casino only gets to keep a fairly indistinct percent of all the plays put out.
The casino slot machine software controls every part of the machine, from the flashing lights to the rolling of the reels.
When you hit spin on the slot machine, a combination is developed by the RNG which connects with the pictures on the reel.
