Modern casino slot machines are controlled by computer software, and the winning percentages are pre-programmed into the game software.
Casino Slots have Random # Generators which are ceaselessly generating combos, even when the slot machine game is not currently being played.
Running side by side with the RNG of the casino slot machine is the pay out rate percent.
The payout percentage controls how much the slot machine game will payout, for e.g. the pay percentage could be ninety percent, meaning the slot machine game will pay out 90% of all the wagers played, and the casino simply gets to keep ten per cent.
This is not to say that each and every time you bet ten credits you will receive nine in return – where’s the fun and exhilaration 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 catch the big top prize.
The profit percentages most likely will vary between the differing games and a few of the extremely popular casinos, for example Golden Online Casino, which hands out a cash payment of up to ninety five percent!
Thus, in essence, the slot machine game takes all the $$$$$ played into it and pays it out to several chosen winners. The casino only gets to keep a basically tiny % of all the bets placed.
The casino slot machine software controls any part of the machine, from the blinking lights to the spinning of the reels.
When you hit spin on the slot machine, a combination is developed by the RNG which connects with the pictures on the reel.
