Modern casino slot machines are controlled by computer chips and software, and the winning %s are pre-programmed into the gaming software.
Casino slot games have Random # Generators which are continually generating combos, even when the slot machine game is not being played.
Running concurrently with the random # generator of the casino one-armed bandit is the pay out per cent.
The payout percentage controls how much the one-armed bandit will payout, for example the payout percent might be ninety percent, meaning the one arm bandit will pay ninety per cent of all the bets played, and the casino only gets to keep ten percent.
This does not mean that every time you bet ten credits you will receive nine in return – where is the fun and fascination in that? Instead, the casino slot just won’t pay out for a bit, and then suddenly go on a hot streak and you might draw the big grand prize.
The profit %s will very likely vary between the various games and a few of the notably favored casinos, for e.g Golden Online Casino, which gives a payout of up to 95 per cent!
Hence, in essence, the one-armed bandit takes all the dough played into it and pays it out to a number of chosen winners. The casino only gets to keep a considerably tiny % of all the plays placed.
The casino one armed bandit software controls each and every part of the machine, from the blinking lights to the revolving of the reels.
When you hit spin on the slot machine, a combination is developed by the RNG which corresponds to the pictures on the reel.
