Modern casino Slots are controlled by computer software, and the win percentages are preprogrammed into the gaming software.
Casino one armed bandits have RNGs that are continuously generating combinations, even when the slot machine is not active.
Running side by side with the Random Number Generator of the casino slot machine game is the pay out per cent.
The payout percentage controls just how much the one-armed bandit will payout, for example the pay percentage could be ninety percent, which means the one arm bandit will pay ninety per cent of all the bets played, … the casino only gets to keep ten percent.
This is not to say that each time you bet 10 credits you will receive nine in return – where is the fun … fascination in that? Instead, the casino slot machine just will not pay out for a while, and then suddenly start up a hot streak and you might hit a big grand prize.
The pay out percentages will vary between the differing games and just a few of the extremely popular casinos, like Golden Online Casino, which gives a payment of up to 95 per cent!
As a result, in essence, the one-armed bandit takes all the currency played into it and pays it out to a number of fortunate winners. The casino only gets to keep a relatively low % of all the plays placed.
The casino slot software controls each part of the machine, from the blinking lights to the rolling of the reels.
When you hit spin on the slot machine game, a combination is formed by the RNG which is linked to the pictures on the reel.
