I'm very curious about the slots probability. Because it's a prime number, where did 1/593 come from? Is the outcome of the slots generated at once (selecting one permutation from an exhaustive list of permutations), or are the slot probabilities calculated independently for each? If it's the latter, is the probability of each slot dependent on the previous outcome, or are all three slots randomly generated such that the probability of any one slot is an independent occurrence?
I'm too lazy/shy to peek under the hood and reverse engineer the answer, so I'd love to hear your thoughts, haha
