Modern casino slot machines are controlled by computer software, and the winner percentages are preprogrammed into the gaming software.
Casino one armed bandits have RNGs that are ceaselessly generating combinations, even when the machine is not currently being played.
Running collectively with the random # generator of the casino slot machine is the payout rate %.
The payout % controls just how much the slot machine will pay out, for eg the pay out percentage might be ninety percent, meaning the slot machine game will pay ninety per cent of all the bets played, … the casino simply gets to keep 10%.
This doesn’t mean that each time you bet ten credits you will receive 9 in return – where’s the fun … excitement in that? Instead, the casino slot machine just will not payout for a little while, and then suddenly go on a hot streak and you might draw the big top prize.
The pay out percentages most likely will vary between the different games and a handful of the most popular casinos, e.g. Golden Online Casino, which gives a payment of up to ninety five per cent!
Thus, in essence, the slot machine takes all the money played into it and pays it out to a couple of fortunate winners. The casino only gets to keep a fairly petite per cent of all the odds allotted.
The casino slot machine software controls every part of the machine, from the dazzling lights to the rotating of the reels.
When you hit spin on the one-armed bandit, a combination is formed by the RNG which corresponds to the pictures on the reel.
