Slot Developers 101

Since the dawn of online slots, software developers have been busy advancing the game, bringing new features, and introducing new technology, and the healthy competition in this ever-growing market is driving innovation. You might be familiar with the big players in this field. Like any modern capitalist marketplace, two of three big players dominate as they try to create a monopoly. This is true of the slots development game, but don’t overlook the little guys. Often, the smaller companies are where you’ll find the real risk-takers, and with so many of our favourite games come from today.

Slot Providers Galore

Some slot providers are known for one trait, whilst some have a reputation for another. There are literally thousands of slot games in existence today and more and more developers enter the scene every year. Here’s a list of the main players in this field, and some examples of what they’ve brought to the table. The age of the Internet and online gambling really opened up space for far more ideas to emerge. There has never been a more eclectic mix of slot games makers out there like there is today.

The Malta-based company has since built a reputation for using 3D animation in its slots and iGaming products, making them some of the best-looking games on the market.

The games are optimised for iOS, Windows Phone and Android devices under the mantel ToGo Games. Our favourite titles include Giovanni’s Gems, The Slotfather Part II and Kawaii Kitty.

Blueprint's tag

Blueprint Gaming

This Newark-based company represents another key player flying the flag for homegrown software development in the UK. The studio is actually part of Germany’s Gauselman Group but develops games for both land-based markets, plus Italy. Its library of online and mobile games is available globally though. Blueprint has been savvy in acquiring licenses for much-loved but niche franchises such as Top Cat, Worms: Reloaded, Viz Magazine and Duckula. It also produces quality original titles.

The logo fo Dragonfish

Dragonfish

As a fully-owned subsidiary of 888 Holdings, you’ll only find Dragonfish games at 888casino in the UK. However, the Casinoflex team at Dragonfish is a worthy entrant into this list due to its library of more than 300 games including exclusive content from 888’s in-house games studio.

It’s Forest Mania, of the most visually attractive slots on the market.

Mazooma's logo

Novomatic's logo

Novomatic

Novomatic was founded in 1980 by the billionaire Johann Graf and now operates in 43 countries today. Graf is now a billionaire and the in 2012 his company’s revenue was €3.2 billion. Despite its monumental success in Europe, Novomatic is not as big a presence on the UK online slots scene as it is on the continent. Some of its biggest games can be found if you know where to look, such as Sizzling Hot Deluxe and Book of Ra.

Playtech's label

Playtech

The final pillar of ‘the big three’, Playtech has been around since 1999 but the company was right there at the birth of online casinos.

Quickspin symbol

Quickspin

Quickspin was acquired by Playtech in 2016 but still operates as a semi-independent company, retaining its own branding and development process. A regular at the EGR Awards,Quickspin has an impressive range of games in its portfolio. The cherry blossom-inspired Sakura Fortune remains a fan favourite. The company is also carved out a niche in developing slots with a light-hearted take on the world of children’s stories. Goldilocks and the Wild Bears and Big Bad Wolf are almost satirical in their approach.

Realtime Gaming logo

Realtime Gaming

Realtime Gaming launched in 1998 out of Atlanta, Georgia. The software development team has since relocated to Costa Rica, but it has continued to deliver on its philosophy of creating serious online gambling games for serious players. You could be forgiven for taking that Realtime mantra with a pinch of salt upon given its library includes titles such as; Builder Beaver, Food Fight and The Big Bopper.

Rabcat brand image

Rabcat

Best known for its game Classic 243 – a flashy 80s neon beauty – that has been a hit with the online slots community and critics of the industry, Rabcat is more than a one-trick-pony.

Yggdrasil's emblem

Yggdrasil Gaming

As the company tagline goes, Yggdrasil is all about ‘superior gaming’. Yggdrasil only gained its first licence in 2013, but the team has wasted no time in catching up to the competition.

Its latest release, Jungle Books, introduces a new mechanic called Fusion Realms, mixing different reel structures into a single game.

Summary

The UK slots market is ready to burst. With so many new developers coming onto the scene, the competition has to be a good thing for players. As companies strive for innovative new ideas, pushing the boundaries of what online can be, the quality of the games is improving dramatically. Some of the above-mentioned developers are strictly online and some have never ventured into the realm of online slots at all. Some are exclusively slots developers, whilst others make a whole host of casino games such as blackjack and roulette. It’s also true that some big names have struggled to adapt to the fast-moving industry we live in today. The multi-millionaire pound mega-companies that have dominated the field for some time have got a fresh crowd of start-ups that are making a lot of noise to deal with.
