Slot machine Types history and definitions: Class III gaming is the Las Vegas/Atlantic City/Cruise Ship type. The machine has its own internal RNG (Random number generator) and all game results are based on pulling numbers from the RNG. The oldest machines were literally mechanical devices that like a roulette wheel relied on the spinning of the device to have a random characteristic. You couldn't theoretically know how to pull the handle to get them to stop anywhere in particular. Results were paid on the random patterns arising from three reels ending up on random places. Later the mechanical reels were replaced by electro-mechanical where a microprocessor would use an RNG to get a random number and from that number send the reel to that position. So three random numbers would yield the same random patterns of the mechanical reels. BTW true mechanical reels are now illegal for casinos in Nevada. With the limited number of patterns on these reels you couldn't afford to design a top prize all that high because the number of stops determined how many possibilities there were. Say you had 22 stops per reel there are only 10,648 combinations so top prize couldn't be higher than 10,648 or you lose money as the casino. And with wanting lower prizes as well and them more common you end up with top prizes no higher than say 2,500 or 5,000 of your coin. So adding reels was done. But also you could use the processor to with an virtual reel having far more stops than physical stops. You'd map more possibilities into spaces or less valuable stops and fewer into more valuable stops (this is an IGT patent btw) So Class III games are defined as these games where an internal RNG determines where the reels go. The player is competing only against math. Another form of Class III is skill based games. Video poker for example. Rather than a result purely based on random numbers you get a preliminary result but based on your 'brains' you can choose something to modify the results. You can choose which cards to keep and which to throw away in video poker and can thus affect your final results though random numbers are still a big part of it. Video version of blackjack are usually in this category too. Class II gaming is one where a player is competing with other players. Like lottery tickets where you are trying to buy the best ticket before someone else does. A pull tab machine is just like that. When you buy a pull tab you get a number that is worth some prize. A pull tab type slot machine lets you buy a number but rather than just give you a slip of paper it takes that number and maps it into a pattern on the reels. Once someone gets the best prize no one else can until all pull tabs are gone and the pool is replaced. The other style of class II is bingo style. I work on bingo machines here. You are literally playing bingo with the machine doing most of the work on buying the card, checking the called balls and daubing your card for you. The results of your bingo game are then translated into a pattern displayed on the reels. But about what I said on skill based video blackjack. We have a bingo based blackjack. It looks like blackjack and you can hit or stay and feel like you are doing something but well not really. The result was determined by bingo so if you stay with a deuce and trey but bingo said you win the dealer will end up going bust. If you keep hitting trying to go bust but bingo says you win you will hit 21 instead. So that make sense? Prolly more than you really wanted to know.
