What is Online Casino Software?

“Casino software” describes the various platforms and technologies on which online casino games are played. This can include:

  • How the games look and feel
  • The technology hosting the games (cloud-based, downloaded software, mobile app)
  • Game fairness, RTP and payouts
  • Stylistic elements (bonuses, graphic, gameplay)
  • Types of games (slots, table games, live dealer games etc)

A single online casino can incorporate software from dozens of different game developers, leading to a multitude of gaming experiences within a single platform. For example, Microgaming and NetEnt are both famous and successful game developers—but the playing experience is vastly different for each.

Online casino software is arguably the most crucial differentiator between top-class and bottom-rung casinos.

UK Software Casinos Without GamStop

When looking for new online casinos not on GamStop, it’s paramount that they have high-quality casino software—if not, players will be unable to enjoy their favourite games.

Since every developer builds their games in a unique way, there are therefore consistent and notable differences between developers. So, let’s take a look at some of the best game providers at non-GamStop online casinos.

Microgaming

microgaming

One of the oldest casino game providers in the world, Microgaming casino sites are highly coveted by players. Microgaming is known for producing games which are exceptionally volatile and highly-paying. Its progressive jackpot game Mega Moolah is the highest-paying online casino game in history, unleashing a jackpot of over €19 million in 2021.

However, Microgaming casino sites don’t stock games by other providers. Players may also have to download desktop software or mobile apps to play Microgaming games, but thankfully most Microgaming casino sites now support in-browser play.

The only downside is that Microgaming casino games are usually quite basic in terms of visuals, interactiveness and bonus rounds.

NetEnt

NetEnt games are probably the most popular in the industry. Famous for blockbuster graphics, NetEnt slots are often closer to video games than classic slots. NetEnt online casinos allow rapid in-browser play on any device. Even better, most of their games can be played for free in demo mode—something that other casinos not on GamStop might not offer.

While best-known for slots, NetEnt casino games also include progressive jackpots, RNG table games and an incredibly immersive live dealer suite. The Swedish giant’s games are innovative, beautiful and, we’re happy to report, regularly available at non-GamStop casinos!

Novomatic

While they sometimes fly under the radar, Novomatic slots are some of the biggest in the entire industry! For example, Book of Ra is played at most of the world’s online casinos, reeling in thousands of players every single day. The game loads quickly and offers a max return of 5,000x stake and has a 30% hit frequency.

Other slots at Novomatic online casinos are Sizzling Hot Deluxe, Dolphin’s Pearl, and Lucky Lady’s Charm. While none of these slots offer Pixar-level graphics or storylines, they provide something even more valuable: big wins. You’ll find Novomatic slots at most casinos not on GamStop.

RTG

Real Time Gaming

Real Time Gaming was founded in 1998 in Atlanta, and has become one of the biggest American online gaming brands—despite moving its operations to Costa Rica. RTG online casinos are best known for their fun array of online slots. Games like Cleopatra’s Gold, Casino War, Aztec Millions and Mayan Queen may not have the same brilliance as NetEnt slots, but they pay generously and attract millions of players around the world.

Most games are available for instant play, though some RTG casinos still use downloadable desktop software.

Betsoft

Betsoft

Betsoft casinos are a perennial hit among online casino players, yet despite that popularity, the developer only has about 200 games to its name—Microgaming released half that number in 2021 alone!

You’ll recognise Betsoft online casino games by their old-fashioned graphics and animations. Unlike some modern providers, Betsoft doesn’t try to be innovative—it just produces solid, enjoyable games for its loyal player base. Check out “The Slotfather” series or Greedy Goblins to see Betsoft’s best work!

Evolution Gaming

Evolution Gaming

Evolution Gaming casinos have been the runaway kings of live dealer games for over a decade. There is no one in the industry that can match the diversity of games (blackjack, roulette, baccarat, sic bo, poker variations, bingo, and much more) or the quality of execution.

Evolution Gaming online casino software is incredibly polished. It’s easy to navigate and the design is perfectly modern. Most importantly, the company employs over 3,000 professional dealers—by far the most charming, experienced and entertaining in the business. Players can even enjoy 15+ languages at more than 700 tables worldwide.

All games available in-browser for instant play.

Rival Gaming

Rival Gaming

Founded in 2005, Rival Gaming now boasts over 250 games that can be played on any device. Their famous i-Slots are available in many Rival Gaming casinos—these trademarked games feature an interactive storyline that sets them apart from regular slots.

Rival Gaming online casinos find a nice balance between building sufficiently complex and attractive games, without over-engineering and overwhelming players.

Pragmatic Play

Pragmatic Play

Pragmatic Play is one of the more adventurous online casino game providers. Their goal is not simply to create fun games—it’s to dazzle and delight players with groundbreaking graphics, innovative game modes and high-volatility payouts.

While Pragmatic Play casinos are best-known for Wolf Gold and the John Hunter video slots, a small number also supply RNG and live dealer table games! You can tell a true Pragmatic Play casino by the inclusion of live Bonanza Candyland—the live dealer adaptation of their iconic video slot!

Thunderkick

Thunderkick

While they sometimes fly under the radar, Thunderkick online casinos punch far above their weight. An independent Swedish game developer with bold ideas, Thunderkick has risen to prominence thanks to its superbly entertaining games, built on its absurdly high-quality casino software.

The casino is well-known for creating games that are fair, with generous and extremely consistent payouts—something that veteran online casino players do not take for granted. The developer’s Beat the Beast series is particularly popular, with nearly a dozen variations.

Casinos Not Blocked by GamStop Software

If you’re new to the world of non-GamStop online casinos, we’ve got great news: there are dozens to choose from! These are all safe, high-quality online casinos which are not blocked by GamStop software. We have reviewed all the best, brightest and newest casinos and you can find our favourites right here:

Games not on GamStop

You might be worrying that some of your favourite games will be prohibited by GamStop—we’re happy to report that this is very unlikely!

The game providers we’ve described above are only some of the many, many developers whose games are available on non-GamStop casinos. And while it’s true that, for example, a NetEnt online casino might not stock all NetEnt games, there are no specific games which are restricted by GamStop.

Summary

The software at today’s non-GamStop casinos is every bit as polished and high-quality as anywhere else. From Microgaming casino sites to those hosting 30 or 40+ game developers, we are enjoying a golden era in online gaming.

It used to be that every casino required downloadable software that was clunky, slow, and prone to disconnection. Now we have non-GamStop casinos with thousands of world-class games, hosted on slick and high-performance platforms that are accessible on any device, on any operating system.

We are entering a real golden age of online casino gaming!
