Modern casino one armed bandits are controlled by computer software, and the win %s are preprogrammed into the software.

Casino slot machines have Random # Generators which are ceaselessly generating combinations, even when the machine is not being played.

Running in unison with the random # generator of the casino one-armed bandit is the payout percent.

The payout per cent controls how much the slot machine will payout, for e.g. the payout per cent could be ninety percent, meaning the one arm bandit will pay ninety per cent of all the stakes played, and the casino gets to keep ten per cent.

This doesn’t mean that for every time you bet ten credits you will receive 9 in return – where is the fun and excitement in that? Instead, the casino slot machine won’t payout for a bit, and then suddenly start up a hot streak and you might hit a big jackpot.

The pay out %s usually will vary between the alternate games and a couple of the very famous casinos, for example Golden Online Casino, which puts forth a payment of up to 95 %!

Therefore, in essence, the one-armed bandit takes all the currency played into it and pays it out to some lucky winners. The casino only gets to keep a considerably small percent of all the odds allocated.

The casino one armed bandit software controls every single part of the machine, from the flashing lights to the circulating of the reels.

When you hit spin on the slot machine game, a combination is set up by the RNG which corresponds to the pictures on the reel.
