Modern casino Slots are controlled by computer chips and software, and the winning %s are pre-programmed into the computer software.
Casino slot games have RNGs that are continuously generating combos, even when the slot machine is not being played.
Running in sync with the RNG of the casino slot machine is the pay out rate percent.
The pay out per cent controls just how much the slot machine will payout, for example the pay out per cent could be ninety percent, which means the slot game will payout ninety per cent of all the wagers played, … the casino will then get to keep 10 per cent.
This does not mean that every time you bet 10 credits you will receive 9 in return – where’s the fun and excitement in that? Instead, the casino one arm bandit will not payout for a bit, and then suddenly go on a hot streak and you might hit a big pot prize.
The pay off percentages usually will vary between the alternate games and just a few of the most famous casinos, e.g. Golden Online Casino, which hands out a cash payment of up to 95 %!
As a result, in essence, the slot machine game takes all the dough played into it and pays it out to several lucky winners. The casino only gets to keep a averagely indistinct per cent of all the gambles allocated.
The casino one armed bandit software controls each and every part of the machine, from the flickering lights to the turning of the reels.
When you hit spin on the one-armed bandit, a combination is produced by the RNG which corresponds to the pictures on the reel.
