Casino Software Providers

B

Big Time Gaming

The Sydney studio that invented Megaways — the engine that redraws a slot's reel layout every spin, up to 117,649 ways on a six-reel grid. Bonanza made the mechanic famous in 2016, licensing spread it across the industry, and Evolution bought the company in 2021.

C

Cryptologic

A history page more than a casino list: Cryptologic supplied InterCasino, which took the first real-money online wager in 1996, signed the industry's first Marvel slots deal, and paid a record $8 million jackpot in 2007 before the brand was broken up after its 2012 sale to Amaya.

I

IGT

International Game Technology's machines — Megabucks from 1986, the licensed Wheel of Fortune games — were Nevada fixtures before Cleopatra went online. Published returns across the catalogue run from 95.24% to 99.74%, and since July 2025 the gaming business has been owned by Apollo-managed funds.

i

iSoftBet

Founded in London in 2010 and part of the IGT group since 2022. Branded slots such as 24 and Basic Instinct are the recognisable names, but the GAP aggregation platform is the reason iSoftBet titles turn up in so many multi-provider UK lobbies.

M

Microgaming

One of the longest-running suppliers in online gambling — Isle of Man, founded 1994 — with a 600-plus-title library now distributed through Games Global. Mega Moolah, its four-tier progressive network, seeds at £1 million and has paid some of the largest online jackpots on record.

N

NetEnt

Swedish, founded 1996, and deliberately smaller in catalogue than its rivals: Starburst and Gonzo's Quest carry the reputation. NetEnt sells individual browser-based games rather than platforms, so no two lobbies stock quite the same set. Part of Evolution since 2020, which now supplies the live tables.

N

NextGen Gaming

Slots were the entire catalogue from the 1999 Sydney founding onwards — no tables, no live dealer. Foxin Wins, 300 Shields and Medusa still circulate in UK lobbies with published returns of roughly 94–98%, though the studio itself now sits two takeovers deep inside Light & Wonder.

N

Novomatic

Johann Graf's Austrian group started with gaming cabinets in 1980 and came online late, through its Greentube subsidiary. Book of Ra and Sizzling Hot earned their fame on land, and the roughly 200-title online catalogue reaches fewer UK lobbies than the name would suggest.

P

Play'n GO

Book of Dead's studio, working from Växjö in southern Sweden since 1997 and supplier-licensed by both the UKGC and Malta's MGA. Reactoonz — a 7×7 cluster-pays grid returning 96.51% — is the other title UK players search for, within a published catalogue range of roughly 92–98%.

P

Playtech

Teddy Sagi founded it in 1999; today it's a London-listed group of around 500 games that sells operators the whole stack — platform, live dealer, poker and the Age of the Gods progressive network. That platform model concentrates its UK volume at large bookmaker-led operators.

P

Pragmatic Play

Gates of Olympus, Sweet Bonanza and the Big Bass series are more famous than the studio's own name. Taking its current form in Malta in 2015, it releases new titles at a pace older rivals rarely attempt and runs live dealer and bingo verticals besides slots, with published RTPs of 93.45–96.92%.

R

Rival Gaming

Not a UKGC-licensed supplier — no UK-licensed casino carries its games, and our guide says so plainly. The Cyprus-based studio's claim to attention is the i-Slot, an episodic story format launched years before interactive slots became fashionable; catalogue returns average around 96.3%.

T

Thunderkick

A Stockholm company of about eighty people that has built only slots since 2012, distinctive enough for far larger operators to stock them. Esqueleto Explosivo's exploding mariachi skulls remain the signature, and payout rates across the catalogue sit between 94 and 98%.

Y

Yggdrasil

Fredrik Elmqvist left NetEnt to found this Malta-based studio in 2013, and it dropped Flash for HTML5 within months — years ahead of the industry. Vikings Go Berzerk and Valley of the Gods lead a slots catalogue whose partner-published returns span 94.45% to 98.24%.
