Modern casino slot machine games are controlled by computer software, and the winner percentages are preprogrammed into the software.
Casino slot machines have RNGs that are continuously generating combos, even when the slot machine is not currently being played.
Running in sync with the RNG of the casino one-armed bandit is the pay out rate percentage.
The pay out per cent controls just how much the slot machine will payout, for e.g. the payout per cent could be ninety per cent, meaning the slot machine will payout ninety percent of all the stakes played, … the casino gets to keep ten per cent.
This does not mean that every time you bet ten credits you will receive 9 in return – where’s the fun … excitement in that? Instead, the casino slot machine game won’t pay out for a bit, and then suddenly jump on a hot streak and you might hit a big pot prize.
The pay out %s will tend to vary between the different games and just a few of the most favored casinos, for example Golden Online Casino, which tenders a cash payment of up to ninety five percentage!
This means that, in essence, the slot machine game takes all the $$$$$ played into it and pays it out to a couple of lucky winners. The casino only gets to keep a relatively indistinct per cent of all the bets made.
The casino slot machine software controls every part of the machine, from the flickering lights to the rotating of the reels.
When you hit spin on the slot machine, a combination is formed by the RNG which is linked to the pictures on the reel.
