Modern casino Slots are controlled by computer chips and software, and the win percentages are pre-programmed into the software.
Casino slot machines have Random # Generators that are continuously generating combinations, even when the slot machine game is not being played.
Running synchronously with the random # generator of the casino slot machine is the payout percent.
The payout percentage controls how much the slot machine game will pay, for e.g. the pay out percentage could be ninety per cent, meaning the slot machine will payout ninety percent of all the stakes played, and the casino gets to keep 10 per cent.
This does not imply that for every time you bet 10 credits you will receive nine in return – where is the fun … exhilaration in that? Instead, the casino slot machine will not pay out for a while, and then suddenly fire up a hot streak and you might draw the big jackpot.
The pay off percentages will most likely vary between the a variety of games and a few of the very famous casinos, such as Golden Online Casino, which gives a pay out rate of up to 95 per cent!
Hence, in essence, the slot machine takes all the $$$$$ played into it and pays it out to a handful of fortunate winners. The casino only gets to keep a averagely low per cent of all the stakes allotted.
The casino one armed bandit software controls every single part of the machine, from the dazzling lights to the circulating of the reels.
When you hit spin on the slot machine, a combination is produced by the RNG which associates with the pictures on the reel.
