Modern casino slot machines are controlled by a computer, and the win percentages are preprogrammed into the software.
Casino slot machines have Random Number Generators which are continuously generating combos, even when the slot machine game is not active.
Running jointly with the random # generator of the casino one-armed bandit is the pay out rate percentage.
The payout per cent controls how much the one-armed bandit will pay out, for example the pay out percent could be ninety percent, meaning the one arm bandit will pay ninety percent of all the wagers played, … the casino simply gets to keep 10%.
This does not imply that for every time you bet 10 credits you will receive 9 in return – where is the fun and thrill in that? Instead, the casino slot machine will not pay out for a while, and then suddenly fire up a hot streak and you might hit a big grand prize.
The profit %s will vary between the alternate games and just a few of the notably acclaimed casinos, for example Golden Online Casino, which hands out a pay out of up to ninety-five %!
So, in essence, the slot machine game takes all the $$$$$ played into it and pays it out to a few chosen winners. The casino only gets to keep a relatively minute percent of all the gambles allocated.
The casino one armed bandit software controls any part of the machine, from the blinking lights to the turning of the reels.
When you hit spin on the one-armed bandit, a combination is generated by the RNG which is linked to the pictures on the reel.
