Modern casino slot games are controlled by computer software, and the win percentages are pre-programmed into the game software.
Casino slot machine games have RNGs which are continually generating combos, even when the machine is not active.
Running concurrently with the RNG of the casino slot machine game is the pay out rate per cent.
The pay out % controls how much the slot machine game will payout, for eg the pay out per cent may be ninety percent, meaning the slot game will payout ninety percent of all the bets played, … the casino gets to keep ten percent.
This does not imply that for every time you bet ten credits you will receive nine in return – where’s the fun and fascination in that? Instead, the casino slot will not pay out for a little while, and then suddenly fire up a hot streak and you might draw the big grand prize.
The payoff percentages will very likely vary between the alternate games and a handful of the notably popular casinos, for e.g Golden Online Casino, which hands out a payment of up to ninety-five percent!
So, in essence, the one-armed bandit takes all the currency played into it and pays it out to a handful of lucky winners. The casino only gets to keep a considerably indistinct percent of all the wagers put out.
The casino slot machine software controls every single part of the machine, from the flashing lights to the rolling of the reels.
When you hit spin on the slot machine, a combination is set up by the RNG which corresponds to the pictures on the reel.
