The iGaming industry, both in the UK and internationally, has experienced enormous growth in the past few years. Changes to laws in the United Kingdom have made online casinos and sports gambling brands more common and accessible than ever. Meanwhile, consumers have access to faster and better smartphones and tablets, making online gambling more convenient than ever—and certainly much easier than heading to a land-based casino. 

With the rise of iGaming brands in the United Kingdom, we are sure you want to know which ones are the biggest, growing the fastest, and how they became so successful. So, let’s dive in right in!

Blueprint Gaming

Known for its 50 games and popular features like the progressive jackpot found in Plenty O’ Fish, Blueprint is based out of the United Kingdom but has also extended internationally into Italy and Canada. 

Immersive games with strong visuals are what make Blueprint stand out from the competition. With their newest game, 777 Deluxe, they have blended the best of a retro slot machine with easy, modern controls and an energetic soundtrack.


Much of what has propelled Blueprint Gaming to new heights of success comes from its partnerships. In March 2024, Blueprint announced its partnership with popular UK casino brand Sky Vegas to launch Reel Rivals, a free multiplayer slot game played against other players on a time limit to win prizes. 

Paddy Power

Paddy Power is a well-known sports bookie in the United Kingdom with hundreds of physical retail locations. However, in 2016, Paddy Power and Betfair merged to form Flutter Entertainment, making them a new powerhouse in both online gaming and sports betting. 

With all the games and gambling services Paddy Power has to offer, it’s no surprise to see them growing 17% in revenue year over year, with 11% more players enjoying their games in the UK specifically.

Online gamblers love Paddy Power for its easy-to-use app and recent developments like the Money Back Special, which gives players a chance to earn something back if they come close to winning on some sports bets.


Like Paddy Power, Playtech is a major player in the international iGaming space and is on the leading edge of software development. Playtech uniquely combines sports and mobile-based casino gambling, like online slots and card games. Their technology also allows for a live, virtual casino for bettors who want a more immersive experience that reminds them of the mood and atmosphere of a casino.

Many players love Playtech games for their gorgeous graphics and how easy they are to play. They also love the fact that their low minimum bets make them accessible to all who want to play for longer stretches without going overboard with their spending.

Playtech’s growth has been big, especially in the last year. Its expansion into the Americas increased the company’s revenue by 43%, showing the true power of its presence in the iGaming industry.


Betfred specializes in arcade gambling games and sports betting. Like Paddy Power, Betfred has more than 1,500 locations throughout the United Kingdom—the first of which opened in 1967. While their many retail locations faced significant challenges during the pandemic, expansion into more online games and opening their website to some American states has prompted plenty of year-over-year growth. The company’s customers wagered £8.8 billion in 2023—more than £1.8 billion more than they did in 2022.

The company also renewed a deal in 2023 with the previously mentioned Playtech. The new agreement involves Betfred and Playtech installing more on-demand terminals throughout their United Kingdom locations, which will serve the many customers who enjoy stopping in.

Red Tiger Gaming

Red Tiger Gaming is not as big as some other companies on this list, but they do enjoy a large presence on the online gambling scene due to their immersive games. Their team is devoted to creating memorable gaming experiences, particularly slots and card games, that combine eye-popping artwork and cutting-edge technology. Many of their games are rated very highly on review sites like

Evolution, an even larger iGaming software provider, bought Red Tiger Gaming in 2020, and the innovation this dream team is capable of is taking the industry to new heights. It’s no wonder they are the world’s biggest casino software company!


Founded in 2000 by Denise Coates, Bet365 is another massive online gambling company providing access to online casino games like cards and slots as well as sports gambling. They are perhaps best known for having over two dozen sports to bet on and promos that ensure loyalty to irresistible rewards for new players signing up and making their first deposits. 

Players have also raved about the easy-to-use app, which puts Bet365 in the mobile-centric realm that iGaming users want the most during leisure time. 

Bet365 has also dabbled in using state-of-the-art technology, including virtual and augmented reality, to make its games more immersive and enjoyable. These work especially well among players seeking a casino-like experience while playing from basically anywhere. 

For all these reasons and more, the company has grown to be one of the world’s largest iGaming companies—with Denise’s personal net worth estimated at £9.5 billion.


iGaming has come a long way in the United Kingdom. While many gamers still love in-person casinos, there is something about the ease of use of online casinos that is irresistible. And thanks to betting platforms and software providers like those above continuously pushing the envelope, today’s punters can experience unique and innovative gambling experiences at home or on the go.
