Modern casino slot machine games are controlled by a computer, and the winning percentages are pre-programmed into the computer software.
Casino slot machines have Random Number Generators that are continually generating combos, even when the machine is not currently being played.
Running synchronously with the random # generator of the casino slot machine game is the pay out percentage.
The payout % controls how much the slot machine game will pay out, for example the pay percent may be ninety per cent, which means the slot machine will pay ninety percent of all the wagers played, and the casino only gets to keep 10 percent.
This is not to say that every time you bet 10 credits you will receive 9 in return – where is the fun … exhilaration in that? Instead, the casino one arm bandit won’t pay out for a little while, and then suddenly hit a hot streak and you might hit a big top prize.
The profit percentages will vary between the various games and several of the most popular casinos, for e.g Golden Online Casino, which tenders a payment of up to 95 percent!
As a result, in essence, the one-armed bandit takes all the money played into it and pays it out to a couple of chosen winners. The casino only gets to keep a averagely low per cent of all the plays allotted.
The casino slot machine software controls each and every part of the machine, from the flickering lights to the revolving of the reels.
When you hit spin on the slot machine, a combination is put together by the RNG which connects with the pictures on the reel.
