From what I heard is that there is firmware (permanent memory) in slot machines with a list of outcomes, past and future that can be audited by the gaming commission.
Therefore the performance is planned. It may never produce a jackpot if the list has been exhausted and repeated. I’m thinking there are folks in the MGM office laughing their heads off.
Stick to craps-roullette-blackjack.
There is no way to predict future outcomes and they are not planned.
The machines can be audited to confirm the randomness of past results and percentage of past payouts but that’s it.
Basically when you pull the lever, the machine instantly generates a random number (or combinations of numbers). Jackpots are calculated based on the chance of certain jackpot numbers appearing at random.
A combination of numbers than has a 1:1000 chance of appearing might pay out 1:900 for example. The difference between the statistical chance and payout ratio is the house take. In this case the house gets 10%
