Modern casino slot machines are controlled by a computer, and the winning percentages are pre-programmed into the software.
Casino slot machines have Random # Generators that are continuously generating combos, even when the slot machine game is not currently being played.
Running in sync with the RNG of the casino one-armed bandit is the pay out percent.
The payout percent controls just how much the slot machine game will pay, for example the pay out per cent may be 90%, meaning the slot machine will pay out ninety per cent of all the bets played, … the casino simply gets to keep 10 per cent.
This does not imply that every time you bet 10 credits you will receive 9 in return – where is the fun and thrill in that? Instead, the casino slot machine game will not payout for a little while, and then suddenly go on a hot streak and you might draw the big pot prize.
The profit %s usually will vary between the alternate games and a few of the highly famous casinos, for example Golden Online Casino, which gives a payout rate of up to ninety five percentage!
Thus, in essence, the one-armed bandit takes all the money played into it and pays it out to a number of privileged winners. The casino only gets to keep a fairly tiny per cent of all the odds allocated.
The casino slot software controls any part of the machine, from the flashing lights to the spinning of the reels.
When you hit spin on the slot machine, a combination is generated by the RNG which relates to the pictures on the reel.
