Modern casino slot games are controlled by a computer, and the win percentages are preprogrammed into the software.
Casino one armed bandits have Random Number Generators which are continually generating combos, even when the machine is not currently being played.
Running jointly with the RNG of the casino slot machine is the pay out %.
The pay out % controls just how much the one-armed bandit will pay out, for eg the pay percent could be ninety per cent, meaning the one arm bandit will pay 90% of all the stakes played, and the casino gets to keep ten percent.
This is not to say that each time you bet ten credits you will receive 9 in return – where is the fun … fascination in that? Instead, the casino slot won’t pay out for a bit, and then suddenly start up a hot streak and you might draw the big jackpot prize.
The pay out %s will definitely vary between the differing games and some of the highly acclaimed casinos, e.g. Golden Online Casino, which gives a payment of up to ninety-five percent!
Hence, in essence, the slot machine game takes all the $$$$$ played into it and pays it out to some privileged winners. The casino only gets to keep a averagely minute percent of all the gambles placed.
The casino slot software controls each and every part of the machine, from the flickering lights to the turning of the reels.
When you hit spin on the slot machine, a combination is formed by the RNG which is linked to the pictures on the reel.
