Modern casino slot machine games are controlled by a computer, and the winning percentages are pre-programmed into the gaming software.
Casino slot machines have RNGs that are continually generating combinations, even when the machine is not active.
Running synchronously with the random # generator of the casino one-armed bandit is the payout rate %.
The payout percentage controls how much the slot machine will payout, for eg the pay out % might be ninety percent, which means the slot machine game will payout ninety per cent of all the wagers played, and the casino gets to keep 10%.
This is not to say that each time you bet ten credits you will receive 9 in return – where is the fun … thrill in that? Instead, the casino slot just won’t pay out for a while, and then suddenly go on a hot streak and you might hit a big jackpot.
The payout %s will most likely vary between the alternate games and just a few of the most famous casinos, for instance Golden Online Casino, which puts forth a cash payment of up to 95 %!
As a result, in essence, the slot machine takes all the cash played into it and pays it out to a number of fortunate winners. The casino only gets to keep a relatively small percent of all the odds allotted.
The casino slot machine software controls any part of the machine, from the dazzling lights to the turning of the reels.
When you hit spin on the one-armed bandit, a combination is put together by the RNG which associates with the pictures on the reel.
