Modern casino Slots are controlled by computer software, and the winning %s are preprogrammed into the game software.
Casino slot machine games have Random Number Generators that are endlessly generating combos, even when the machine is not currently being played.
Running jointly with the RNG of the casino slot machine is the pay out percentage.
The payout percentage controls just how much the slot machine game will payout, for example the payout percentage may be 90%, which means the one arm bandit will pay 90% of all the stakes played, … the casino simply gets to keep ten per cent.
This does not mean that each and every time you bet 10 credits you will receive 9 in return – where’s the fun … thrill in that? Instead, the casino slot just won’t pay out for a while, and then suddenly go on a hot streak and you might draw the big jackpot.
The pay out percentages will tend to vary between the different games and a few of the notably acclaimed casinos, for example Golden Online Casino, which provides a payout of up to ninety five per cent!
Therefore, in essence, the one-armed bandit takes all the cash played into it and pays it out to a number of lucky winners. The casino only gets to keep a relatively indistinct per cent of all the plays placed.
The casino slot software controls each part of the machine, from the blinking lights to the turning of the reels.
When you hit spin on the slot machine game, a combination is formed by the RNG which connects with the pictures on the reel.
