Modern casino slot machines are controlled by computer chips and software, and the win percentages are pre-programmed into the game software.
Casino slot machines have Random Number Generators that are constantly generating combos, even when the slot machine game is not being played.
Running in unison with the Random Number Generator of the casino one-armed bandit is the pay out %.
The payout percent controls just how much the one-armed bandit will pay out, for example the payout % might be ninety percent, meaning the slot machine will payout 90% of all the bets played, … the casino simply gets to keep ten percent.
This doesn’t imply that for every time you bet ten credits you will receive nine in return – where is the fun and exhilaration in that? Instead, the casino slot machine game just won’t payout for a little while, and then suddenly hit a hot streak and you might catch the big jackpot.
The profit percentages will definitely vary between the alternate games and several of the most acclaimed casinos, for example Golden Online Casino, which tenders a payment of up to ninety five percent!
So, in essence, the slot machine game takes all the currency played into it and pays it out to a couple of fortunate winners. The casino only gets to keep a relatively small percentage of all the odds placed.
The casino slot software controls every part of the machine, from the flashing lights to the spinning of the reels.
When you hit spin on the slot machine, a combination is set up by the RNG which is linked to the pictures on the reel.
