Most Popular Slots in the World

There are thousands of slot games that you can play anytime on the internet. This is not an exaggeration. There are providers with more than 600 slot machines in their collection, and online slots have been in development for almost 30 years, so it’s not surprising that there are thousands of different options. But predictably, quantity is not the same as quality: only some of these games manage to enter the popular slots category.

The number of players decides which games are the best online slots. Some slot machines attract more attention than others and are played by more people. We will discuss the reasons for this below, but for now, let’s state that this situation varies according to the culture: each country has a different list of popular slots. In this article, we will talk about the best online slots and give lists of popular slots by country. As always, you can play every game listed below for free at SlotoZilla.

What Makes Slots Popular

Did you know that slot games make up more than 70% of casinos’ revenues? The biggest reason for this is that slots are “equalizing” games. Your chances of winning against a professional poker player are slim because experience makes a difference in this game. In general, this is true for almost all card and table games. However, in slot games, knowledge and experience do not matter: professional gamblers and beginners have the same chances of winning. In just 10 minutes, you can learn how to play the game and win millions if you’re lucky enough. You don’t need to spend a lifetime learning how to play these games.

So, who decides which slots will become popular? As mentioned above, this is an issue determined by the number of players. Some titles attract more players, and this could be for many reasons. For example:

  • Big payouts: Some games have such high payouts that every player wants to try their luck. Mega Moolah developed by Microgaming is a good example. This game made its way into the Guinness Book of Records with a payout of 18 million Euros.
  • High variance: Some online slot machines have low payout frequency, but when they pay out, the amount is extremely high. These games are preferred the most because they offer high winning potential.
  • High-quality graphics: The graphics and animation quality of some games is so high that they are played just for an immersive experience. The slots developed by RabCat can be given as an example.
  • Simple rules and bonuses: Nobody wants to think long and hard and waste time on learning the rules or trying to find out if they have won a prize or not. It is possible to say that slots with simple rules and bonuses are generally more popular.
  • Interesting main characters: Some games have an intriguing story and an attractive hero. You can even play just to follow that story. The “Rich Wilde” character created by Play’n GO is a good example of this. There are almost a dozen slots using this character.
  • Popular theme: Some slot themes attract more attention than others. In this context, we can say that the themes of Ancient Egypt, pirates and space almost always attract more players. Using just the right theme can make a game popular.

Slot machines are also products, and like any product, some are more popular than others. There is no single reason for this either, as any (or all) of the things we listed above can cause it. The interesting thing is that popular slot games differ by country. In other words, culture can also be added to this list. Every country prefers different types of games. In the section below, we list the best online slots by country.

Online vs. Offline Slots

But first, let’s answer a question that players are curious about: which is better, online slots or land-based ones? There is no fundamental difference between the two categories in terms of rules; your goal in both is to place identical symbols side by side. However, there are big differences between the two game types in terms of experience, the number of options and chances of winning. If we summarize these differences in a list:

  • Land-based slots also offer a social experience. To play them, you have to travel, enter a casino and interact with other people, not just the games. This is advantageous in some ways, but you have to physically travel every time you want to play: it is not possible to play whenever and wherever you want.
  • Online slots, on the other hand, allow you to turn any place into a casino. Using your laptop, you can access thousands of games without leaving your home. You can also do this whenever and wherever you want, using your mobile phone. Online slots are available wherever you are: you don’t have to travel to access them.
  • In terms of options, online slots have a clear advantage. There is a limit to the number of slot cabinets that can fit in a physical building. Even at the biggest Las Vegas casino, you cannot find more than a few hundred cabinets. In online casinos, there is no space limit: thousands of games can be found on the same website.
  • In terms of chances to win, online slots are more advantageous. The RTP value of Las Vegas slots can legally be 85%. For online slots, this value is 95% on average. So, in the long run, you will lose less and get more of your investment.

In short, online slots are almost always better and put you in control: you decide when and where you want to play. In the table below, you can see the advantages and disadvantages of both game types.

Best Online Slots Globally

As we mentioned above, every country likes different types of slots. In other words, the list of popular slots contains different games in each country. There are legal as well as cultural reasons for this: some countries are not able to access the games of some suppliers. (For example, German players don’t have access to most Netent games.) So, which country prefers to play which slots? We have answered this question by listing the most popular slots by country below.
