Modern casino slot machine games are controlled by computer chips and software, and the win percentages are pre-programmed into the game software.

Casino slot machine games have RNGs which are constantly generating combos, even when the machine is not currently being played.

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

The payout percent controls how much the slot machine game will pay, for example the payout percentage may be ninety per cent, which means the slot machine game will pay out 90% of all the stakes played, and the casino only gets to keep ten per cent.

This doesn’t mean that for every time you bet 10 credits you will receive nine in return – where’s the fun and exhilaration in that? Instead, the casino slot machine will not payout for a while, and then suddenly go on a hot streak and you might draw the big pot prize.

The payout %s will definitely vary between the differing games and a handful of the highly established casinos, for e.g Golden Online Casino, which provides a payment of up to 95 percent!

As a result, in essence, the slot machine game takes all the $$$$$ played into it and pays it out to a handful of fortunate winners. The casino only gets to keep a generally low percent of all the gambles allocated.

The casino slot machine software controls each and every part of the machine, from the blinking lights to the turning of the reels.

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