That doesn’t mean your result will necessarily be better or worse, just different. Because the RNG works so fast, if you pause slightly before your next play or stop for a few seconds to order a beverage or chat with a neighbor, your result will be different than if you kept at the same pace. With more sophisticated RNGs, hitting the “Bet One Coin” button, the “Max Bet” button or pulling the handle could start the algorithm from different points.
So do the entry points to start the next calculation. How many random numbers are used and how they are mapped onto symbols differs from game to game. The RNG works with a full set of numbers on every spin, so all results are possible on every spin.It doesn’t know how those numbers are used. The only function of the RNG is to generate random numbers.
It’s said that nothing in the universe above quantum level is truly random, but random number generators are close enough that players can’t discern any repeating patterns, and the long-term percentages are those you would expect from randomly occurring outcomes.
