Modern casino Slots are controlled by computer chips and software, and the winner percentages are pre-programmed into the gaming software.
Casino slot games have Random # Generators which are continuously generating combinations, even when the slot machine game is not currently being played.
Running in unison with the random # generator of the casino one-armed bandit is the pay out rate %.
The pay out per cent controls how much the one-armed bandit will payout, for example the payout % might be ninety percent, which means the one arm bandit will pay 90% of all the bets played, and the casino only gets to keep 10 per cent.
This doesn’t mean that for every time you bet 10 credits you will receive 9 in return – where is the fun and thrill in that? Instead, the casino slot machine game just won’t pay out for a while, and then suddenly go on a hot streak and you might draw the big pot prize.
The pay off percentages will definitely vary between the different games and just a few of the most popular casinos, for e.g Golden Online Casino, which puts forth a payment of up to 95 percent!
So, in essence, the one-armed bandit takes all the funds played into it and pays it out to some lucky winners. The casino only gets to keep a relatively minute percentage of all the odds placed.
The casino slot software controls each and every part of the machine, from the blinking lights to the rolling of the reels.
When you hit spin on the slot machine, a combination is generated by the RNG which relates to the pictures on the reel.
