Historically, slots have been one of the most popular gambling games. They are simply understood and easy to play. They also open up the portal to more advanced casino games, if a player chooses to explore further. Since the turn of the 21st century, their popularity has grown even more with the advent of online gaming.
In the UK, for example, online casinos reported a revenue of USD 6.5 billion in 2024. This is more than double the levels in 2017. Unsurprisingly, a similar trend is visible for online slots too. In 2015-16, their gross gambling yield (GGY) stood at USD 1.6 billion. By 2021-22, it had almost doubled to USD 3 billion.
How online slots have grown over the years
There are plenty of reasons that have driven the growth of online slots over the years. The most obvious of these is the improvements in the internet. Not only is the reach of the internet widening everyday, its speeds have been improving and the connections themselves are far more stable. As a result, it's easier for players to engage in an online game of slots in a relaxed way.
The fact that online slots can be played across devices like laptops, tablets or smartphones has also added to their ease and convenience. Whether waiting in a queue or during long travels, gamers now have access to them at potentially all times.
Online casinos and game developers on their parts, have added to the appeal of slots as well. No longer are slots only about a single machine with a few trademark signs that imply wins or losses. Players can choose from an array of themes to make the games more exciting.
Themes can range from historic backdrops to movies. There are even sports based themes, like for football. The online slot games could feature a gamer’s favourite team or player. And with the advent of AI, there could also be more in-game animations that make it engaging. In fact, with AI there’s also greater accessibility among players, since color schemes and text sizes, as examples, can be changed to suit unique needs for players.
Mobile gaming drives forward online slots’ demand
Mobile gaming, in particular, could drive online slots forward in the next few years. It already has. Since the time that mobile games came into being, users have enjoyed even the most basic of games. And with smartphone usage and the choice of apps that comes with it, mobile gaming has already reached the next level.
The availability of apps is also advantageous for developers. No longer do they have to depend on retailers to market their products. They can just go viral through social media or even gain organic popularity through downloads by gamers.
This in turn both widens and deepens the reach of online slots. Fresh new games can be made available that were previously unheard of. This can bring in more gamers. Also, as companies recognise the growing popularity of differentiated games, they can be inspired to develop different varieties as well. In a nutshell, this can be a virtuous interconnection that creates growth for everyone involved.
As technologies like AI and virtual reality develop further, they too can support more enjoyable gaming. For beginners to online slots, AI can provide clear instructions. It can even suggest games they might like based on algorithms. Virtual reality can create an immersive experience for gamers, irrespective of the device they use to play. Already, different themes are a big hit among online slot games. But with VR, it can go to a whole new level.
Much further to go
With the kind of progress online slot games have seen already, it’s clear that they can only increase in reach. The growth of online casinos over the years is notable and within that, online slots have also seen massive growth.
Slots have an edge over other casino games in that they are simple to play, so even newbies can flock to them. Playing them is easier than ever before today with the availability of smartphones and better internet connections. The range of apps offering online slots has also grown, resulting in an array of choices for gamers. Game developers have also played a big part in making these games more engaging. Online slots now have a variety of themes available to play with, and can even be based on real life sports like football.
Undoubtedly, though, mobile gaming has been at the heart of rapid growth in these games. They have enabled the deepening of the online slots industry by introducing gamers to fresh new games. This in turn has also provided industry feedback on the new trends in the industry, encouraging more game development. And this is when smartphone penetration is nowhere near complete. As it grows further, online slots could be in for exciting times.
