Modern casino slot games are controlled by computer chips and software, and the win percentages are preprogrammed into the gaming software.
Casino slot machine games have Random # Generators that are eternally generating combos, even when the slot machine is not active.
Running in sync with the RNG of the casino slot machine game is the pay out rate percent.
The pay out per cent controls just how much the slot machine game will pay, for e.g. the pay percent could be ninety percent, meaning the slot machine will payout ninety per cent of all the wagers played, … the casino simply gets to keep 10%.
This doesn’t mean that for every time you bet ten credits you will receive 9 in return – where is the fun and exhilaration in that? Instead, the casino slot just will not pay out for a little while, and then suddenly hit a hot streak and you might hit a big pot prize.
The pay out percentages will vary between the a variety of games and a couple of the most famous casinos, for e.g Golden Online Casino, which gives a payout rate of up to ninety-five percentage!
Hence, in essence, the one-armed bandit takes all the dough played into it and pays it out to a few chosen winners. The casino only gets to keep a relatively small percentage of all the bets allocated.
The casino slot software controls every part of the machine, from the flashing lights to the revolving of the reels.
When you hit spin on the slot machine, a combination is put together by the RNG which associates with the pictures on the reel.
