Modern casino slot machine games are controlled by computer software, and the winning %s are preprogrammed into the computer software.
Casino slot machine games have Random Number Generators that are constantly generating combos, even when the slot machine game is not currently being played.
Running in unison with the random # generator of the casino slot machine game is the pay out per cent.
The payout per cent controls just how much the slot machine game will pay out, for example the payout % could be ninety percent, which means the one arm bandit will pay out 90% of all the stakes played, … the casino will then get to keep 10%.
This does not mean that each time you bet ten credits you will receive nine in return – where’s the fun and excitement 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 catch the big grand prize.
The payoff percentages will very likely vary between the various games and some of the notably favored casinos, for instance Golden Online Casino, which tenders a pay out of up to 95 %!
Hence, in essence, the slot machine takes all the cash played into it and pays it out to a couple of fortunate winners. The casino only gets to keep a considerably minute per cent of all the gambles put out.
The casino slot software controls every part of the machine, from the blinking lights to the turning of the reels.
When you hit spin on the slot machine, a combination is put together by the RNG which associates with the pictures on the reel.
