Modern casino slot machines are controlled by a computer, and the winning %s are preprogrammed into the game software.
Casino slot machines have RNGs which are ceaselessly generating combinations, even when the machine is not active.
Running collectively with the RNG of the casino one-armed bandit is the payout %.
The pay out percent controls just how much the slot machine will pay out, for example the payout percentage could be 90%, which means the slot machine game will pay ninety percent of all the stakes played, … the casino will then get to keep 10%.
This does not imply that for every time you bet 10 credits you will receive 9 in return – where’s the fun … fascination in that? Instead, the casino slot just won’t pay out for a bit, and then suddenly start up a hot streak and you might catch the big pot prize.
The payout %s usually will vary between the various games and a handful of the very acclaimed casinos, e.g. Golden Online Casino, which tenders a cash payment of up to 95 %!
This means that, in essence, the slot machine takes all the dough played into it and pays it out to several fortunate winners. The casino only gets to keep a relatively small per cent of all the wagers placed.
The casino slot software controls any part of the machine, from the flashing lights to the rotating of the reels.
When you hit spin on the slot machine game, a combination is generated by the RNG which corresponds to the pictures on the reel.
