Modern casino slot games are controlled by computer chips and software, and the win %s are pre-programmed into the game software.
Casino one armed bandits have Random Number Generators which are ceaselessly generating combinations, even when the slot machine game is not being played.
Running simultaneously with the RNG of the casino one-armed bandit is the pay out rate %.
The payout % controls just how much the slot machine game will pay, for e.g. the pay out per cent may be 90%, which means the one arm bandit will pay 90% of all the stakes played, … the casino only gets to keep 10 percent.
This is not to say that each time you bet 10 credits you will receive nine in return – where is the fun and exhilaration in that? Instead, the casino slot machine game won’t payout for a little while, and then suddenly jump on a hot streak and you might draw the big grand prize.
The pay out percentages will most likely vary between the assorted games and just a few of the extremely established casinos, for instance Golden Online Casino, which gives a payout rate of up to 95 percentage!
Hence, in essence, the one-armed bandit takes all the cash played into it and pays it out to several chosen winners. The casino only gets to keep a generally tiny percent of all the wagers allocated.
The casino one armed bandit software controls each and every part of the machine, from the blinking lights to the turning of the reels.
When you hit spin on the slot machine game, a combination is produced by the RNG which corresponds to the pictures on the reel.
