Modern casino slot machine games are controlled by computer chips and software, and the winning %s are preprogrammed into the software.
Casino slot games have RNGs which are ceaselessly generating combos, even when the slot machine is not being played.
Running in unison with the random # generator of the casino slot machine is the payout rate percent.
The pay out per cent controls how much the slot machine will pay out, for example the payout per cent might be 90%, meaning the slot machine game will pay ninety percent of all the bets played, and the casino gets to keep 10 percent.
This is not to say that for every time you bet ten credits you will receive 9 in return – where’s the fun … excitement in that? Instead, the casino slot machine won’t pay out for a little while, and then suddenly hit a hot streak and you might catch the big jackpot prize.
The payoff percentages will very likely vary between the a variety of games and several of the notably popular casinos, like Golden Online Casino, which offers a payout of up to ninety five per cent!
So, in essence, the slot machine game takes all the $$$$$ played into it and pays it out to a number of chosen winners. The casino only gets to keep a generally minute percentage of all the bets placed.
The casino slot machine software controls every part of the machine, from the blinking lights to the spinning of the reels.
When you hit spin on the one-armed bandit, a combination is produced by the RNG which is linked to the pictures on the reel.
