Modern casino slot machine games are controlled by computer chips and software, and the win %s are pre-programmed into the game software.
Casino Slots have Random # Generators that are constantly generating combinations, even when the slot machine game is not active.
Running concurrently with the RNG of the casino one-armed bandit is the pay out per cent.
The payout percent controls how much the one-armed bandit will payout, for e.g. the payout percentage could be ninety percent, which means the slot machine will pay out 90% of all the bets played, and the casino simply gets to keep ten per cent.
This doesn’t mean that each time you bet 10 credits you will receive 9 in return – where is the fun … excitement in that? Instead, the casino slot machine won’t pay out for a while, and then suddenly go on a hot streak and you might catch the big pot prize.
The pay off %s will definitely vary between the various games and several of the most favored casinos, for e.g Golden Online Casino, which puts forth a payout of up to ninety five %!
Thus, in essence, the one-armed bandit takes all the dough played into it and pays it out to a few fortunate winners. The casino only gets to keep a relatively indistinct per cent of all the plays made.
The casino slot machine software controls every part of the machine, from the flashing lights to the turning of the reels.
When you hit spin on the slot machine, a combination is set up by the RNG which is linked to the pictures on the reel.
