Modern casino one armed bandits are controlled by computer chips and software, and the winner percentages are pre-programmed into the computer software.
Casino one armed bandits have Random Number Generators which are continually generating combos, even when the game is not currently being played.
Running in unison with the random # generator of the casino slot machine is the payout %.
The pay out % controls how much the slot machine will pay out, for eg the pay percentage may be 90%, which means the one arm bandit will pay ninety per cent of all the stakes played, … the casino only gets to keep ten percent.
This really does not mean that every time you bet ten credits you will receive 9 in return – where is the fun … thrill in that? Instead, the casino slot won’t payout for a while, and then suddenly go on a hot streak and you might draw the big grand prize.
The payout %s will vary between the various games and some of the highly favored casinos, for e.g Golden Online Casino, which provides a cash payment of up to ninety five per cent!
Thus, in essence, the slot machine game takes all the $$$$$ played into it and pays it out to a handful of privileged winners. The casino only gets to keep a considerably small % of all the gambles placed.
The casino slot software controls each and every part of the machine, from the flashing lights to the turning of the reels.
When you hit spin on the slot machine game, a combination is developed by the RNG which connects with the pictures on the reel.
