Modern casino slot machine games are controlled by a computer, and the winning percentages are preprogrammed into the software.
Casino slot games have Random Number Generators which are continuously generating combinations, even when the machine is not active.
Running concurrently with the random # generator of the casino one-armed bandit is the pay out percent.
The payout percentage controls how much the slot machine will pay, for eg the pay out per cent could be 90%, meaning the one arm bandit will pay ninety percent of all the bets played, … the casino gets to keep 10%.
This really does not mean that for every time you bet ten credits you will receive 9 in return – where is the fun … thrill in that? Instead, the casino slot machine game just will not payout for a little while, and then suddenly start up a hot streak and you might draw the big pot prize.
The pay off percentages most likely will vary between the alternate games and a handful of the most common casinos, for example Golden Online Casino, which offers a pay out of up to ninety five percentage!
Thus, in essence, the slot machine game takes all the funds played into it and pays it out to a couple of privileged winners. The casino only gets to keep a generally small percent of all the stakes allocated.
The casino one armed bandit software controls any part of the machine, from the flickering lights to the revolving of the reels.
When you hit spin on the one-armed bandit, a combination is set up by the RNG which corresponds to the pictures on the reel.
