Modern casino one armed bandits are controlled by computer software, and the winning %s are pre-programmed into the computer software.
Casino slot machine games have Random Number Generators which are continually generating combinations, even when the slot machine game is not currently being played.
Running in unison with the RNG of the casino one-armed bandit is the payout rate per cent.
The payout per cent controls just how much the one-armed bandit will pay out, for e.g. the pay out % may be ninety percent, which means the slot machine game will pay out ninety percent of all the stakes played, and the casino simply gets to keep ten percent.
This does not mean that each time you bet 10 credits you will receive 9 in return – where’s the fun … fascination in that? Instead, the casino slot machine game will not payout for a while, and then suddenly go on a hot streak and you might catch the big pot prize.
The pay off %s shall vary between the differing games and some of the highly acclaimed casinos, for example Golden Online Casino, which puts forth a pay out rate of up to ninety five per cent!
As a result, in essence, the one-armed bandit takes all the money played into it and pays it out to some privileged winners. The casino only gets to keep a fairly small per cent of all the gambles allotted.
The casino slot machine software controls every single part of the machine, from the flickering lights to the circulating of the reels.
When you hit spin on the slot machine game, a combination is formed by the RNG which associates with the pictures on the reel.
