Modern casino slot machine games are controlled by computer chips and software, and the win %s are pre-programmed into the game software.
Casino slot machines have Random # Generators that are eternally generating combos, even when the machine is not being played.
Running in sync with the Random Number Generator of the casino slot machine game is the pay out rate %.
The payout % controls just how much the slot machine will payout, for eg the pay out per cent could be ninety percent, which means the slot game will pay out 90% of all the wagers played, … the casino simply gets to keep 10 percent.
This does not mean that for every time you bet ten credits you will receive nine in return – where’s the fun and excitement in that? Instead, the casino one arm bandit will not pay out for a little while, and then suddenly fire up a hot streak and you might hit a big jackpot prize.
The profit percentages will most likely vary between the various games and a few of the notably famous casinos, like Golden Online Casino, which gives a pay out rate of up to ninety-five per cent!
Hence, in essence, the slot machine takes all the $$$$$ played into it and pays it out to a handful of chosen winners. The casino only gets to keep a considerably small per cent of all the stakes allotted.
The casino one armed bandit software controls each and every part of the machine, from the blinking lights to the revolving of the reels.
When you hit spin on the slot machine game, a combination is generated by the RNG which corresponds to the pictures on the reel.
