Modern casino slot machine games are controlled by computer chips and software, and the winning %s are pre-programmed into the software.

Casino one armed bandits have Random Number Generators which are ceaselessly generating combos, even when the slot machine game is not active.

Running collectively with the RNG of the casino one-armed bandit is the payout rate percent.

The pay out per cent controls how much the slot machine will pay, for e.g. the pay out per cent may be ninety percent, which means the slot machine game will pay out 90% of all the wagers played, … the casino gets to keep ten per cent.

This does not mean that each and every time you bet ten credits you will receive 9 in return – where’s the fun and excitement in that? Instead, the casino one arm bandit just won’t payout for a little while, and then suddenly jump on a hot streak and you might draw the big top prize.

The payout %s will tend to vary between the various games and just a few of the very established casinos, for instance Golden Online Casino, which tenders a pay out of up to 95 per cent!

Hence, in essence, the one-armed bandit takes all the currency played into it and pays it out to several lucky winners. The casino only gets to keep a relatively low percentage of all the wagers allotted.

The casino slot machine software controls any part of the machine, from the blinking lights to the circulating of the reels.

When you hit spin on the one-armed bandit, a combination is set up by the RNG which connects with the pictures on the reel.
