Modern casino slot machine games are controlled by computer software, and the winning %s are pre-programmed into the game software.
Casino Slots have Random # Generators which are continuously generating combinations, even when the machine is not active.
Running jointly with the random # generator of the casino slot machine is the pay out rate percent.
The payout per cent controls just how much the slot machine game will payout, for e.g. the pay percentage could be ninety percent, meaning the slot machine game will pay ninety per cent of all the bets played, and the casino simply gets to keep 10 percent.
This doesn’t mean that every time you bet 10 credits you will receive nine in return – where is the fun … excitement in that? Instead, the casino slot machine will not pay out for a little while, and then suddenly jump on a hot streak and you might hit a big jackpot prize.
The pay out percentages usually will vary between the different games and a handful of the highly popular casinos, for example Golden Online Casino, which hands out a payout rate of up to 95 percentage!
As a result, in essence, the slot machine takes all the currency played into it and pays it out to some privileged winners. The casino only gets to keep a fairly small % of all the gambles placed.
The casino one armed bandit software controls every single part of the machine, from the blinking lights to the rolling of the reels.
When you hit spin on the slot machine game, a combination is set up by the RNG which associates with the pictures on the reel.
