Modern casino slot machine games are controlled by computer software, and the winning percentages are preprogrammed into the software.
Casino Slots have Random # Generators which are continually generating combos, even when the slot machine is not being played.
Running concurrently with the Random Number Generator of the casino slot machine game is the payout rate %.
The pay out percent controls how much the one-armed bandit will pay, for eg the pay per cent may be ninety percent, meaning the slot machine will pay 90% of all the wagers played, … the casino simply gets to keep 10 per cent.
This is not to say that each and every time you bet ten credits you will receive nine in return – where’s the fun … excitement in that? Instead, the casino slot machine game just will not payout for a little while, and then suddenly fire up a hot streak and you might catch the big jackpot.
The pay off %s usually will vary between the alternate games and several of the highly established casinos, e.g. Golden Online Casino, which provides a pay out of up to 95 per cent!
This means that, in essence, the slot machine takes all the $$$$$ played into it and pays it out to some lucky winners. The casino only gets to keep a averagely minute percent of all the stakes placed.
The casino slot software controls each part of the machine, from the blinking lights to the rotating of the reels.
When you hit spin on the one-armed bandit, a combination is set up by the RNG which associates with the pictures on the reel.
