Online casinos have not only a very interesting origins history, but a very interesting legal history as well. With so many different countries having very different attitudes to gambling and games of chance, it is very complicated for the online casinos to satisfy their requirements – yet, they manage to do that and continue serving patrons around the world. This is true especially in the United States where the 51 states have different laws – some allow, some don’t, while others are in-between or on the fence, when it comes to playing online slots, casino games or betting.

Differences in Casino Regulation

This brings us to the matter of the different classes of slots. There exist Class I, Class II and Class III slots and many players are asking the question What Is The Difference Between Class II and Class III slots? The answer to this question does not have any implications on you as a player and mainly concerns the casinos. But it may be interesting to know the difference, at least for those players out there who are gambling history buffs. The various classes of slots are described in the legislation that pertains to the classes of gaming. So we understand that there are three classes of gaming also: Class I Gaming, Class II Gaming and Class III Gaming.

Class II gaming has a lot to do with everything that is associated with the concept of electronic gaming, including the machines that deliver it. The wording defines to some specifics what is a Class II gaming machine, which does not include slots, but various games such keno, bingo and virtual games. Such a machine conveys the ability for a player to engage in gaming via “electronic, computer or other technological aids.”

In the United States and as part of the Indian Gaming Regulatory Act, the gaming options that fall under Class II Gaming are such that do not include any banking on the part of the house. What this means is, any game in which the player is pitted against other players and not the house, belong to the Class II of games. Such may be video poker virtual machines, blackjack virtual machines and other games that remove the house dealer from the gameplay.

What Is The Difference Between Class II And Class III Slot Games?

Yet, it is somewhat confusing because some slots have been qualified as Class II, in which case, the slot machines are to solely placed in venues such as racetracks, where other games exist such as bingo, tip jars, instant bingo and games similar to it. So the slots machine can replica bingo, but it cannot be a full-blown slot machine that has the ‘house’ as the only player involved besides the player pulling the lever.

However, the major difference between the two classes is related to mathematics and payouts probabilities. Simply said, Class III slots are built to contain a Random Number Generator, which is a probability machine of ultra sophisticated mathematics that ensure that the slot machine can not be rigged or tampered with, or in other words, that all winnings are paid out in random sequences. On the other hand, Class II slots are such that are connected to a server, on which the gaming platform supplies the winning odds and probabilities.

Most Slots Are In Face Class III

So if you were to visit Las Vegas remain assured that all of the slots machines will belong to the Class III category, whereas, the various gambling jurisdictions that provide casinos and parlors with the right to provide slots and various games to the patrons, do belong to the Class II category. And just a brief mention of Class I machines. These are basically really simple machines that barely qualify as gambling machines, such as basic bingo and some simple lotteries.

Some of the companies that supply Class III software, meaning slots, to the land based casinos are those that lead the industry with output and innovation. Such companies that dominate the land-casino circuit in the United States and Canada are Ballys, Williams, Wager Works or newly under the International Gaming Group banner, Scientific Games and others.
