Does the RNG control free spins too?24 July 2006
Dear Bob, The RNG is used to determine the results of the free spins too. The only difference between a free spin and regular spin is that you didn't need to pay for the free spin. Best of luck in and out of the casinos,
Dear bryon1, The central computer in Class II gaming draws a set of numbers and sends them down to the slot machines. The slot them covers the numbers on its bingo card and if the pattern matches one of the patterns corresponding to a winning combination, the reels will stop on that combination. The central computer does not tell machines that they have won. The actual paybacks on machines approach their long-term paybacks for the same reason that the same thing happens on Class III devices. Each number is equally likely to be drawn, each pattern will be covered with a frequency very close to that predicted by the probability of covering it, therefore each machine will pay back a percentage very close to its long-term payback percentage. Random Sampling with Replacement governs Class II devices too. I don't know whether all denominations participate in the same drawing or if there are separate drawings for the different denomination. I would think that there is just the one drawing. Perhaps someone in the industry with experience with Class II devices can send me a definitive answer, which I would be happy to publish in a future column. Best of luck in and out of the casinos,
Dear Steven, et al., Thanks to you and all the others who pointed out my error. I changed the payback percentage when I ran the calculations to make the numbers easier to follow and neglected to change the payback percentage in the text. I have corrected the text of the article. The point of the example, if I may repeat it, is to show that after machines have had a reasonable amount of play, jackpots have very little effect on the machines' actual paybacks. It's like a drop of food coloring in a bathtub. Best of luck in and out of the casinos,
Dear Jim, Any of those scenarios (lease or purchase, resell or junk) is possible. Best of luck in and out of the casinos,
