slot machinesSince the first online casinos emerged in the late 1990s, online slot games have become a mainstay of the online gambling industry. Initially, online slot games were limited in terms of their graphics and gameplay, often replicating the classic three-reel fruit machines found in land-based casinos. However, as technology has advanced, online slots have evolved to offer a more immersive and engaging gaming experience.

One of the most significant developments in online slot games has been the introduction of video slots. These games feature advanced graphics, animations, and sound effects, making them more visually appealing and exciting to play. Video slots also introduced a wider range of themes, from popular movies to TV shows and are often included in most people's top 20 slots favourites.

In recent years, Megaways slots have become increasingly popular among UK players. These games offer a unique and innovative way of playing online slots, with up to 117,649 ways to win on each spin. Megaways slots feature dynamic reels that can change in size and shape with each spin, creating more opportunities for players to win big. Advancements in technology have also played a key role in the evolution of online slots. HTML5 and other programming languages have allowed game developers to create more complex and feature-rich games that can be played across multiple devices, including desktops, laptops, smartphones, and tablets.

The popularity of online slots shows no signs of slowing down, with new games and features being introduced on a regular basis. From classic slots to Megaways and beyond, online slot games continue to evolve and offer players an exciting and engaging gaming experience.

First Real Online Slots Super Power

Microgaming is a pioneering online casino software provider that has played a significant role in the emergence and evolution of online slots. Founded in 1994, Microgaming developed the world's first online casino software, which paved the way for the growth of the online gambling industry. Microgaming's first online slots games were simple three-reel games that were based on traditional slot machines. However, the company quickly expanded its offerings, developing more complex and innovative games that featured advanced graphics and animations, as well as exciting bonus features and progressive jackpots. One of Microgaming's most significant contributions to the online slots industry was the development of the first progressive jackpot slot game, Cash Splash, in 1998. This game featured a linked progressive jackpot that could be won by players at any Microgaming-powered casino, and it quickly became one of the most popular games in the industry.

Even though an innovator, many slot studios are around today as successful and growing in ever exciting online slots market. Now is the time to look at the different types of slots available today and show how they have gone from one arm bandits to the world of Megaways!

What are the different types of Online Slots Games today?

Classic Slots

Classic slots are some of the oldest and most iconic slot games available. They are based on the original slot machines that were first invented in the late 1800s and early 1900s. These early machines had mechanical reels that would spin when a player pulled a lever, and they typically had symbols such as fruits, bars, and lucky sevens. Online classic slots are based on this original concept, but they are designed to be played on digital devices such as computers and smartphones. They usually have three reels, although some variations may have more, and they typically have only one payline running horizontally across the middle of the reels. This makes the gameplay very straightforward, as players simply need to match symbols along this payline to win a prize. The symbols used in classic slots are often based on the original symbols used in early slot machines. For example, players may see symbols such as cherries, lemons, oranges, plums, bars, and lucky sevens. The sound effects and graphics used in classic slots are often simple and retro, designed to evoke the feel of playing on an old-school slot machine.

While classic slots may not have the flashy graphics, complex gameplay, or bonus features of some of the newer slot games available today, they remain popular among many players. They offer a simple and straightforward gaming experience that is easy to understand and can be very satisfying when players hit a winning combination. Many online casinos offer a variety of classic slot games alongside more modern variations, giving players the chance to enjoy a wide range of slot experiences.


Video slots are a type of online slot game that has become increasingly popular in recent years. Unlike classic slots, which have only three reels and a limited number of paylines, video slots usually have five reels and can offer hundreds or even thousands of ways to win on each spin. One of the defining features of video slots is their advanced graphics, animations, and sound effects. These games often feature high-quality 3D graphics, immersive sound effects, and animated symbols that can make the gameplay more engaging and entertaining. Video slots also often include a range of exciting bonus features that can add to the excitement of the gameplay. These can include free spins, bonus games, wild symbols, and more. Bonus features can be triggered by landing specific symbols or combinations of symbols on the reels, and can offer players the chance to win big prizes or unlock even more bonus features.

Another feature of video slots is the ability to customize the gameplay experience. Players can often adjust the number of paylines, the size of their bets, and other settings to suit their preferences and playing style. Some video slots also offer the option to autoplay, which allows players to sit back and watch the game play itself for a set number of spins.


Megaways slots are a relatively new type of online slot game that was first introduced by Australian game developer Big Time Gaming in 2016. These games offer a unique gameplay experience that is based on a dynamic reel system that can offer thousands or even tens of thousands of ways to win on each spin. Unlike traditional slots, where each reel has a fixed number of symbols, Megaways slots use a dynamic reel system where each spin can have a different number of symbols on each reel. This means that the number of possible ways to win can vary from spin to spin, and can range from a few hundred up to tens of thousands. The dynamic reel system used in Megaways slots allows for a high degree of unpredictability and excitement in the gameplay. Players never know how many ways to win will be available on each spin, and the potential for big wins can be very high. In addition to the dynamic reel system, Megaways slots often include a range of bonus features such as cascading reels, expanding wilds, and free spins. These features can add to the excitement of the gameplay and offer players more opportunities to win big.

Due to their unique gameplay and potential for big wins, Megaways slots have become increasingly popular among players in recent years. Many of the biggest names in online slots, such as Blueprint Gaming, Red Tiger Gaming, and Pragmatic Play, have released their own Megaways slots, and new games are being added to the genre all the time.


Cluster Pays slots are a relatively new type of online slot game that differs from traditional slot games in how they determine wins. Instead of relying on paylines, Cluster Pays slots pay out based on clusters of symbols that are adjacent to each other on the reels. To form a winning cluster, players need to land a certain number of identical symbols adjacent to each other. The exact number of symbols required to form a cluster and the minimum size of the cluster can vary depending on the specific game. In general, however, larger clusters and more symbols in a cluster will result in bigger payouts. Cluster Pays slots offer a unique gameplay experience that can be particularly engaging for players who enjoy slot games with more complex and varied mechanics. These games can also be visually striking, with colourful and animated symbols that come together to form clusters on the reels.

In addition to the cluster pays mechanic, Cluster Pays slots can also feature a range of bonus features and special symbols, such as wild symbols and free spins, that can increase the chances of forming winning clusters and boost payouts.

Feature Buy Slots

Feature buy slots, also known as bonus buy slots or buy-in slots, are a relatively new type of online slot game that offer players the ability to purchase a game's bonus feature for a set price, rather than waiting for the feature to trigger randomly during gameplay. In most feature buy slots, the bonus feature is a free spins round with special features, such as multipliers or extra wild symbols, that can significantly increase payouts. By purchasing the bonus feature, players can skip the base game and immediately access the potentially more lucrative bonus round. The cost of buying the bonus feature can vary from game to game, and is usually determined by the potential payout of the bonus feature. The higher the potential payout, the higher the cost to buy the bonus feature. While feature buy slots can be exciting for players who are looking for the chance to immediately access the game's bonus feature, they also come with a higher level of risk. Players may spend a significant amount of money on buying the feature without receiving the desired payout, and it's important to gamble responsibly and within your means.

Overall, feature buy slots offer a unique and potentially lucrative gameplay experience that can appeal to players who are willing to take on a higher level of risk. However, it's important for players to exercise caution and only spend what they can afford to lose.

Branded slots are a type of slot game that is based on popular brands, franchises, or characters from movies, TV shows, or other media. These games feature recognizable characters, sound effects, and music, and are designed to appeal to fans of the brand or franchise. Branded slots are often licensed from major entertainment companies, and can feature characters from franchises such as Marvel Comics, Star Wars, or Game of Thrones. They can also feature popular musicians, athletes, or celebrities. The graphics, sound effects, and music on branded slots are often of a higher quality than on other types of slots, in order to fully immerse players in the brand or franchise. Branded slots can offer a unique and exciting gaming experience for fans of the brand or franchise. They often include special bonus features and mini-games that are themed around the brand or franchise, adding an extra layer of excitement to the gameplay. Branded slots can also be a great way for fans to interact with their favorite characters or brands in a new and exciting way. However, it's important to note that branded slots may not offer the same level of payouts as other types of slots, as a portion of the game's budget goes towards licensing the brand or franchise. It's important for players to gamble responsibly and within their means, and to always read the game rules and paytable before playing to fully understand the game's mechanics and potential payouts.
