Modern casino slot machine games are controlled by a computer, and the winning %s are pre-programmed into the software.
Casino slot machines have RNGs which are eternally generating combinations, even when the game is not being played.
Running synchronously with the Random Number Generator of the casino one-armed bandit is the pay out percentage.
The payout % controls how much the one-armed bandit will payout, for eg the pay out per cent might be ninety percent, meaning the slot game will payout 90% of all the stakes played, and the casino will then get to keep 10%.
This does not mean that each and every time you bet ten credits you will receive nine in return – where is the fun and fascination in that? Instead, the casino slot just won’t pay out for a bit, and then suddenly jump on a hot streak and you might draw the big grand prize.
The pay out %s will vary between the various games and several of the notably common casinos, for e.g Golden Online Casino, which puts forth a pay out of up to ninety five percent!
Hence, in essence, the one-armed bandit takes all the dough played into it and pays it out to a couple of lucky winners. The casino only gets to keep a generally indistinct % of all the bets allocated.
The casino one armed bandit software controls each part of the machine, from the flickering lights to the spinning of the reels.
When you hit spin on the slot machine, a combination is formed by the RNG which corresponds to the pictures on the reel.
