Modern casino Slots are controlled by a computer, and the win %s are pre-programmed into the gaming software.
Casino slot machine games have RNGs that are continuously generating combinations, even when the machine is not being played.
Running simultaneously with the RNG of the casino slot machine is the payout %.
The pay out % controls how much the slot machine will pay out, for example the payout per cent may be 90%, which means the slot game will pay out 90% of all the bets played, and the casino gets to keep 10%.
This is not to say that each and every time you bet ten credits you will receive nine in return – where’s the fun … thrill in that? Instead, the casino one arm bandit just will not payout for a bit, and then suddenly jump on a hot streak and you might draw the big jackpot prize.
The payout %s will vary between the different games and a couple of the very established casinos, e.g. Golden Online Casino, which hands out a cash payment of up to ninety five per cent!
This means that, in essence, the one-armed bandit takes all the cash played into it and pays it out to a couple of chosen winners. The casino only gets to keep a considerably minute % of all the odds placed.
The casino slot machine software controls each and every part of the machine, from the flashing lights to the circulating of the reels.
When you hit spin on the one-armed bandit, a combination is put together by the RNG which corresponds to the pictures on the reel.
