The Different Categories of Games

The most popular casino games played online are categorized according to the type of game and its basic rules. Many games can fall into more than one category. We run through these main categories below.

Online Casino Games and the House Edge

Games are categorized by the size of the house edge and, therefore, some of the most popular casino games for gamblers are those that have low house edges. The more adventurous players may decide to risk their gameplay with high house edge games that promise a bigger payday. We explore the house edge category in more detail below.

Low House Edge Games

Games with a low house edge give gamblers a reasonable opportunity to win and particular games are known to have sustained low house edges. These games include Blackjack, Baccarat, and PaiGow Poker.

Some gamblers find it a thrilling prospect, however, to challenge the house at their own game and possibly walk away with their pockets filled. Some of the most popular casino games with the highest house edges are Keno, American Roulette, and specific types of Online Slots games.

Skill Factor Required For Casino Games

Online games are programmed to generate random outcomes, so gamblers rely mostly on luck to bank the big win. There is, however, some element of skill that enables players to navigate through the uncertainty of playing online. Those games that have a high skill factor tend to be more popular options for some gamblers as they enjoy exerting their influence over their results wherever possible.

For most gamblers though, they prefer gambling purely with lady luck on their side.

High Skill Factor

Gamblers who enjoy influencing their choices love playing Blackjack as that is the game with the highest skill factor. Players are responsible for every decision that they make and that determines their chances of winning.

Card counting is a skill used to influence the outcome of Blackjack and although it is hard to learn, it can be used to master Blackjack.

Video Poker also requires a high skill level as players must be certain of which cards to discard and which ones to keep.

Low Skill Factor

Some of the most popular casino games are those with a low skill factor. Players who engage with these low skill games generally understand that their decisions will have a limited influence on the overall house edge but not enough to circumvent it.

Pure Chance

Some games provide loads of entertainment but are games of pure chance. Although they are some of the most popular casino games amongst gamblers, players decisions have no effect on their chances of winning.

Additionally, their gameplay will not mitigate any effect that the house edge has.

Games that fall under this category are Slots, Baccarat, and Roulette.

Which Casino Game Is The Best?

The beauty of playing at an online casino is that there is such an incredible variety of entertainment on offer for all types of personalities, characters, and tastes. With the diversity of gamblers that visit these platforms, it is not an easy proposition to classify the best game. Gamblers have their specific preferences and many would give you good reasons to choose their games of choice.

While some players love spending time at the slots, other gamblers would frown at wasting valuable time and money watching fancy lights and reels spin. Some players enjoy the simplicity of Blackjack, while others may get bored at the slow pace of the game that requires a lot of thought.

Each gambler decides on their own what they believe the best game to be. Although there is no correct answer, you must always take the following factors into consideration:

  • The house edge must be considered before playing any game online. Those that have a low house edge will provide more value for money in the long term.
  • The potential payout undoubtedly influences where a gambler chooses to use his casino credits. Some games dangle an enticing carrot by giving gamblers an opportunity to win big for a relatively small stake.
  • The skill factor definitely needs to be considered when choosing a game to partake in. Players must decide if they wish to gamble with a lot of thinking involved, or just hope for the best.
  • Entertainment is the underlying factor as to why so many people flock to online casinos. You must decide what games you really enjoy and which offer the most amount of fun for you. Gambling is ultimately about having fun, and winning money while having fun is even better.

The Bottom Line

There is no hard and fast rule about picking a favorite or playing the same types of games each time you visit the platform. As nice as consistency is, it is also important to explore all options available at the casino.

Trying a new game every now and then is great for experiencing all that the house has to offer.
