Modern casino one armed bandits are controlled by computer chips and software, and the win percentages are preprogrammed into the gaming software.
Casino slot machine games have RNGs that are continually generating combos, even when the slot machine is not currently being played.
Running concurrently with the RNG of the casino one-armed bandit is the pay out percent.
The payout percent controls how much the slot machine game will pay, for example the pay percent might be ninety per cent, which means the slot machine will pay 90% of all the stakes played, and the casino will then get to keep ten per cent.
This doesn’t imply that each time you bet ten credits you will receive 9 in return – where’s the fun … excitement in that? Instead, the casino slot machine will not payout for a while, and then suddenly jump on a hot streak and you might draw the big grand prize.
The payoff %s will very likely vary between the differing games and a few of the most favored casinos, for e.g Golden Online Casino, which offers a payout of up to 95 percentage!
Hence, in essence, the one-armed bandit takes all the cash played into it and pays it out to some privileged winners. The casino only gets to keep a relatively small percent of all the gambles put out.
The casino slot machine software controls each part of the machine, from the flickering lights to the turning of the reels.
When you hit spin on the slot machine, a combination is set up by the RNG which associates with the pictures on the reel.
