Modern casino slot games are controlled by computer chips and software, and the win %s are preprogrammed into the software.
Casino slot machines have Random # Generators which are constantly generating combinations, even when the slot machine is not active.
Running concurrently with the RNG of the casino slot machine is the payout percent.
The payout percent controls just how much the slot machine will pay out, for e.g. the pay percent might be ninety percent, which means the one arm bandit will payout 90% of all the stakes played, … the casino simply gets to keep ten per cent.
This doesn’t imply that every time you bet 10 credits you will receive nine in return – where’s the fun and excitement in that? Instead, the casino slot machine game won’t payout for a while, and then suddenly start up a hot streak and you might draw the big pot prize.
The payout percentages usually will vary between the a variety of games and a couple of the most common casinos, such as Golden Online Casino, which hands out a cash payment of up to 95 per cent!
Therefore, in essence, the one-armed bandit takes all the $$$$$ played into it and pays it out to a couple of fortunate winners. The casino only gets to keep a basically low per cent of all the plays made.
The casino slot software controls every single part of the machine, from the flickering lights to the turning of the reels.
When you hit spin on the slot machine, a combination is developed by the RNG which connects with the pictures on the reel.
