Modern casino slot games are controlled by computer chips and software, and the winner percentages are preprogrammed into the game software.
Casino Slots have Random Number Generators which are ceaselessly generating combos, even when the slot machine game is not active.
Running simultaneously with the RNG of the casino one-armed bandit is the payout rate percentage.
The payout percent controls just how much the one-armed bandit will pay, for eg the pay out % might be ninety per cent, which means the slot machine will pay out ninety per cent of all the wagers played, and the casino only gets to keep ten per cent.
This is not to say that for every time you bet 10 credits you will receive 9 in return – where is the fun … thrill in that? Instead, the casino slot machine just will not payout for a bit, and then suddenly fire up a hot streak and you might hit a big jackpot prize.
The pay off percentages most likely will vary between the assorted games and just a few of the notably popular casinos, for example Golden Online Casino, which gives a pay out of up to 95 per cent!
Hence, in essence, the one-armed bandit takes all the money played into it and pays it out to a few fortunate winners. The casino only gets to keep a generally indistinct percent of all the gambles made.
The casino slot software controls any part of the machine, from the dazzling lights to the rotating of the reels.
When you hit spin on the slot machine, a combination is produced by the RNG which connects with the pictures on the reel.
