Modern casino slot machine games are controlled by computer software, and the winner percentages are preprogrammed into the computer software.
Casino Slots have Random Number Generators which are endlessly generating combinations, even when the slot machine is not currently being played.
Running in sync with the random # generator of the casino slot machine game is the payout rate percentage.
The pay out per cent controls how much the slot machine game will payout, for example the pay out % could be 90%, which means the slot machine game will pay out ninety per cent of all the bets played, and the casino only gets to keep 10 per cent.
This does not mean that each and every time you bet ten credits you will receive 9 in return – where is 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 hit a big jackpot.
The payoff %s will tend to vary between the various games and just a few of the notably famous casinos, for example Golden Online Casino, which offers a cash payment of up to ninety five per cent!
Hence, in essence, the slot machine game takes all the funds played into it and pays it out to a handful of fortunate winners. The casino only gets to keep a basically low % of all the stakes made.
The casino slot software controls every single part of the machine, from the flashing lights to the spinning of the reels.
When you hit spin on the slot machine game, a combination is formed by the RNG which associates with the pictures on the reel.
