Modern casino slot machines are controlled by a computer, and the win %s are pre-programmed into the computer software.
Casino Slots have Random # Generators which are constantly generating combinations, even when the slot machine game is not being played.
Running simultaneously with the random # generator of the casino slot machine is the pay out %.
The payout % controls just how much the one-armed bandit will payout, for eg the pay out percent might be 90%, meaning the slot machine game will pay out 90% of all the wagers played, and the casino only gets to keep ten percent.
This does not imply that each time you bet ten credits you will receive nine in return – where’s the fun and exhilaration in that? Instead, the casino slot will not pay out for a little while, and then suddenly go on a hot streak and you might catch the big top prize.
The payoff percentages shall vary between the various games and some of the notably common casinos, for e.g Golden Online Casino, which gives a payment of up to ninety-five per cent!
Hence, in essence, the one-armed bandit takes all the cash played into it and pays it out to a handful of privileged winners. The casino only gets to keep a basically tiny percent of all the bets allocated.
The casino slot machine software controls any part of the machine, from the dazzling lights to the circulating of the reels.
When you hit spin on the slot machine, a combination is formed by the RNG which associates with the pictures on the reel.
