Modern casino one armed bandits are controlled by computer chips and software, and the winning %s are pre-programmed into the software.
Casino slot machines have Random Number Generators which are continuously generating combinations, even when the machine is not active.
Running simultaneously with the random # generator of the casino one-armed bandit is the payout %.
The payout per cent controls just how much the slot machine game will payout, for e.g. the pay out per cent might be 90%, meaning the slot machine game will payout ninety percent of all the bets played, … the casino will then get to keep ten per cent.
This doesn’t imply that each time you bet ten credits you will receive 9 in return – where is the fun and thrill in that? Instead, the casino slot machine will not pay out for a while, and then suddenly jump on a hot streak and you might hit a big pot prize.
The profit percentages will very likely vary between the alternate games and a handful of the notably established casinos, for e.g Golden Online Casino, which puts forth a pay out of up to ninety five percent!
So, in essence, the slot machine game takes all the currency played into it and pays it out to a number of chosen winners. The casino only gets to keep a relatively minute percentage of all the stakes allotted.
The casino slot software controls any part of the machine, from the blinking lights to the turning of the reels.
When you hit spin on the slot machine, a combination is developed by the RNG which connects with the pictures on the reel.
