Game Providers
Online casinos don't build their own games. They license them from studios that specialise in slots, live dealer games, or both. The studios an operator works with tell you a lot about the quality and variety of their library. Here's a breakdown of the major providers you'll see across the operators on this site.
Evolution Gaming
The dominant name in live casino. Evolution runs studios in multiple countries and streams live dealer games to hundreds of operators. If an operator has a strong live casino section, it's almost always built around Evolution tables. You'll see their blackjack, roulette, baccarat, and game-show-style titles like Dream Catcher and Crazy Time on most of the sites we list.
Evolution acquired NetEnt and Red Tiger in 2020, so some operators bundle those studios under the Evolution banner. The quality is consistent across all three brands.
NetEnt
A Swedish studio with a back catalogue that includes Starburst, Gonzo's Quest, and Dead or Alive. NetEnt slots are fixtures on UK operators, and many welcome offers centre around NetEnt titles because they're recognisable and widely played. The studio focuses on polished, mid-volatility slots with clean graphics and straightforward mechanics.
Pragmatic Play
A prolific studio that releases new slots and live dealer games at a rapid pace. Pragmatic Play covers everything from high-volatility slots like The Dog House to live casino tables that rival Evolution's offering. You'll find their games on most operators, and their mobile optimisation is strong.
Microgaming
One of the oldest names in online casino software. Microgaming built the first true online casino in the mid-1990s and still produces a steady stream of slots and progressive jackpot games. Their Mega Moolah series has paid out some of the largest jackpots in online gambling history. The studio's catalogue is massive, covering thousands of titles across decades.
Play'n GO
A Swedish studio that produces high-quality slots with strong themes and mechanics. Book of Dead is their best-known title, and it's a staple on UK operators. Play'n GO slots tend toward higher volatility, with big potential wins and longer dry spells between bonus rounds.
Red Tiger
Now part of the Evolution family, Red Tiger focuses on Asian-themed slots and feature-rich mechanics. Their daily jackpot network is popular with operators because it guarantees a win every day, which keeps players engaged. The studio's slots are visually polished and built for mobile.
Playtech
A veteran studio that covers slots, live casino, and virtual sports. Playtech's live dealer offering is Evolution's main competitor, and some operators prefer Playtech tables for their exclusive branded games. The studio also produces the Age of the Gods progressive jackpot series, which is widely played in the UK.
Smaller Studios
Beyond the big names, you'll find dozens of smaller providers on most operators. Studios like Yggdrasil, Quickspin, Blueprint Gaming, Big Time Gaming, and Push Gaming each bring something distinct, whether it's innovative mechanics, high volatility, or niche themes. An operator that stocks games from these studios alongside the mainstream providers usually offers more variety.
Why Provider Mix Matters
An operator with only one or two providers will have a narrower library than one working with ten or fifteen studios. That doesn't always mean worse, but it does limit your options. If you're new to online casino, start with an operator that covers the major studios, so you can try a range of styles and volatilities before you settle on what you like.
Provider mix is one of the eight criteria we assess when scoring operators. A strong partnership network signals an operator that invests in their game library and keeps it fresh.
