Modern casino slot games are controlled by computer software, and the winning percentages are pre-programmed into the software.
Casino one armed bandits have Random Number Generators which are eternally generating combinations, even when the slot machine game is not being played.
Running concurrently with the Random Number Generator of the casino slot machine game is the pay out percent.
The payout percentage controls how much the slot machine game will pay out, for eg the payout % may be ninety percent, which means the slot machine game will payout 90% of all the wagers played, and the casino will then get to keep 10 per cent.
This does not mean that each and every time you bet ten credits you will receive nine in return – where is the fun … thrill in that? Instead, the casino slot just will not pay out for a while, and then suddenly hit a hot streak and you might draw the big grand prize.
The pay out percentages shall vary between the different games and some of the extremely common casinos, for e.g Golden Online Casino, which offers a payout rate of up to ninety five per cent!
Thus, in essence, the one-armed bandit takes all the dough played into it and pays it out to a number of chosen winners. The casino only gets to keep a basically small % of all the odds allocated.
The casino one armed bandit software controls every 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 connects with the pictures on the reel.
