Casino Game Developers — Slot & Live Studios Reviewed

What Do Casino Game Developers Actually Do?

A casino game developer builds the game itself: the maths model that decides how often and how much it pays, the way it uses the random number generator (RNG), the graphics, sound and bonus features. It then has the game tested by an independent lab, licenses it in each market and supplies it to casinos, usually for a share of the money the casino keeps. Hacksaw Gaming’s 2025 annual report, for example, describes earning a “take-rate” on its customers’ gross gaming revenue.

The trade uses several overlapping words, and it helps to know them:

• Developer or game studio: the team that makes the games, such as Thunderkick or Nolimit City.
• Provider or supplier: the company that supplies the games to casinos under its licences, also called a game provider, software provider or content provider. Often it’s the studio itself; sometimes it’s a group that supplies several studios’ games, as Evolution does for NetEnt and Ezugi in Britain.
• Aggregator: a middleman that bundles many studios’ games into one connection. Hacksaw’s annual report describes aggregators as intermediaries that bundle content from multiple game providers and simplify integration.
• Operator: the licensed casino that runs the website, holds your account and money, and handles payments and identity checks.

So whether you search for casino game companies, a casino games developer or an online casino game supplier, you reach the same group of businesses. A game developer company or a casino game software developer is usually just a studio under another name. What separates them is their licences, their maths and how much they tell you about it.

15 Casino Game Developers Compared

This table puts the 15 online casino game developers we’ve reviewed side by side on the facts that don’t change week to week. Game counts are the game developers’ own figures unless noted. The licence column shows licences and certifications as listed in our reviews, among the regulators we cover; a few are the studios’ own claims, which each review marks. For current Trust Scores, use the live compare table above or open each review.

We review casino game developers in batches; these 15 are the first we have published, and more will follow. This guide covers online casino studios only. Makers of casino-floor slot machines are a separate business, and well-known online names such as Push Gaming, Relax Gaming and Blueprint Gaming are not among the 15 yet.

How a Casino Game Reaches You

When you tap a slot in a casino lobby, the game usually isn’t running on the casino’s own servers. It passes through a chain of licensed businesses:

1. The slot game developer or live studio designs the game, its maths and its rules, and has it certified by an independent test lab.
2. The remote gaming server (RGS) hosts the game logic and works out each result. Hacksaw’s annual report says its RGS holds the “game logic and mathematical configuration”, while partner studios on its OpenRGS platform build only the part players see.
3. The aggregator, where one is used, bundles the games of many game developers into a single integration. NetEnt launched its own aggregation platform, NetEnt Connect, in December 2019, with Red Tiger as the first supplier on it. Independent aggregators exist too: SOFTSWISS, the group BGaming came from, says its Game Aggregator gives casinos one API connection to 300+ providers and 40,000+ titles (company figures).
4. The licensed casino adds the games to its lobby, handles your account, deposits and withdrawals, and pays the casino game supplier a share of what it keeps.

Why should you care? Each link can be licensed in a different place, and games from licensed studios sometimes leak to sites that aren’t licensed at all. The UK Gambling Commission warned suppliers in January 2025 that third-party resellers had passed licensed games to illegal sites, and several of the game developers we review have faced regulator action over exactly this (see below). A famous studio’s game in the lobby doesn’t make a casino licensed.

Does a Casino Game Supplier Need a Licence?

In regulated markets, yes, and it’s one of the best protections you get without noticing. In Great Britain, anyone who makes, supplies, installs or adapts gambling software for remote gambling needs a gambling software operating licence under the Gambling Act 2005.

The rule binds the casino too: licence condition 2.2.1 requires every remote casino licensee to use only gambling software made, supplied and installed by holders of that licence. The UKGC adds that the final supplier to a licensed casino needs a licence simply by signing the supply contract, even if it builds nothing itself.

That means a casino licensed by the UK Gambling Commission can only offer games from licensed suppliers, which is why our reviews check every studio’s register entry. Whether it’s a slot game supplier or a live casino studio, the rule is the same. Fourteen of our 15 game developers supply Britain under a UKGC licence, their own or their group’s. We found no UKGC licence for BGaming, so UK-licensed casinos should not offer its games. UK players are better protected on UKGC-licensed sites.

Other markets run their own supplier regimes. Sweden’s Spelinspektionen and Denmark’s Spillemyndigheden license suppliers directly, the Malta Gaming Authority issues B2B critical gaming supply licences, and Germany’s GGL approves virtual slot games one by one. Several of the game developers we review also hold licences in Gibraltar, the Isle of Man and Spain, and Ezugi holds a B2B licence from Curaçao.

Have Casino Game Developers Been Sanctioned? What Regulators Found

A licence isn’t a clean record, so it’s worth knowing what regulators have actually done. The actions below are taken from regulators’ decisions, a court judgment and trade press, as recorded in our reviews. Each concerned games reaching operators that weren’t licensed for the market. None is a finding about a game’s maths or fairness, and lawsuits are not listed here.

How Casino Games Are Tested and Certified

Before a game goes live in a regulated market, an independent testing lab checks it. In Great Britain the game must be tested by a test house the Commission has approved, and the test report submitted before the game is released. Licensees holding both a software licence and a casino licence also need an annual games testing audit, and approved test houses must be accredited to ISO/IEC 17025 plus parts of ISO/IEC 17065 and 27002.

What does a lab actually check? GLI explains that it typically builds its own simulation from the game’s source code, maths documentation and rules, runs billions of simulated rounds to confirm the RTP matches the design and the local minimum, and can force specific outcomes to confirm that every award pays as the rules say. The UKGC’s technical standards then require results to be “acceptably random”, forbid games that adjust to previous results, ban false near-misses, and stop rules, payouts or probabilities changing while a game is available.

Testing doesn’t stop at launch. UK casinos must compare each game’s actual RTP (wins divided by stakes) with its designed RTP, within a tolerance that depends on volatility, and report confirmed faults. Malta’s Player Protection Directive requires casinos’ online RNG games to pay out at least 85% on average, or more where the licence says so. Denmark runs its own certification programme, and Ontario accepts only games certified by an AGCO-registered lab.

Which labs do casino game developers name? According to the companies: NetEnt lists iTech Labs, Technical Services Bureau and GLI; Play’n GO names GLI, BMM and Quinel; Pragmatic Play names GLI, Quinel and Gaming Associates; ELK Studios’ older data sheets name Trisigma (part of the GLI Group since 2024) and GLI; and BGaming says iTech Labs and BMM Testlabs evaluate its RNG.

We found no lab named on the public pages of Thunderkick, Yggdrasil, Playtech, Ezugi or Quickspin, and Hacksaw shows only an eCOGRA logo on its licences page. That doesn’t mean their games are untested, since the regulators receive the reports, but it gives you less to check.

RTP Settings: Why the Same Slot Can Pay Back Less

RTP, or return to player, is the share of all money staked that a game is designed to pay back as winnings over a very large number of rounds. The UKGC stresses that it’s an average over many plays, not what you’ll get in one session. A 96% slot keeps, in theory, 4% of everything staked over its lifetime (the house edge), and your own results can land far above or below that.

The catch is that many casino game developers ship one game in several RTP versions, and the casino chooses which one to run. You can see it in the game developers’ own documents. Quickspin‘s official sheet for Big Bad Wolf Megaways lists three models: 96.05%, 94.11% and 90.19%. Hacksaw Gaming‘s page for Le Prechaun lists five, from 97.52% down to 86.31%. Most ELK Studios sheets since April 2026 allow versions between 96.0% and 87.0%, and Yggdrasil lists every version on its newer game pages, down to 90.5%.

Other game developers publish no RTP on their own pages, which is one reason their RTP Transparency scores are lower. The rule that protects you is disclosure: under the UKGC’s technical standard RTS 3, the RTP (or the chance of winning) and the paytable must be easy to find before you commit to play. The number that counts is the one inside the game at your casino.

Slot RTP, Volatility and Max Win: A Game Maths Glossary

These terms come up in every slot review. Regulators define RTP; the others are standard industry terms, explained here in our own words with examples from our reviews of game developers.

Slot Studios vs Live Casino Studios

Most casino game developers make RNG games, where software decides every result: video slots, scratchcards, crash games and digital table games. Thirteen of our 15 game developers make slots, and slots dominate online casino: Hacksaw’s annual report, citing H2 Gambling Capital, puts online slots at about 75% of the iCasino market.

Live casino studios are a different business. A presenter runs the game from a real table or game-show set, streamed to your device in real time, while you bet on screen. That takes buildings and staff as much as gaming software: Evolution reports about 2,000 live tables, Playtech about 500 at the end of 2025, and Ezugi says it runs 100+ tables from 11 studios and land-based casinos. Pragmatic Play runs its own live casino too.

For players, the differences are practical:

• RTP disclosure: slot game developers increasingly publish RTP per game; live studios often don’t. Evolution shows no RTP on most official game pages, though Crazy Time lists 96.08%.
• Rule tweaks: live variants can change classic odds. Lightning Roulette pays 29:1, not 35:1, on straight-up numbers the lightning doesn’t strike.
• Game shows: Evolution says it created the live game show category with Dream Catcher in 2017.
• Local games: Ezugi specialises in tables such as Andar Bahar, Teen Patti and Cricket War.
• Hybrids: Quickspin and Playtech Live have turned Big Bad Wolf into a live slot.

Digital roulette, blackjack, baccarat and video poker come from RNG studios such as Novomatic, Games Global and NetEnt.

Casino Game Companies: Who Owns Which Game Studio?

Several well-known casino game developers belong to bigger groups, and many guides still describe them as independent. This is the picture for the 15 game developers we review:

Which Slot Game Developer Suits Which Player?

No studio is best for everyone, whatever ranked lists claim. The right slot game developer depends on how you like to play, so this table matches game developers to player types instead of ranking them. It is based on what we found in our reviews:

Free Spins, Demos and New Releases

Casino game developers don’t give players free spins; casinos do. If you want to claim free spins, the offer comes from the casino, with its own terms, wagering requirements, eligible games and expiry dates, and the studio only supplies the game it runs on. Our Bonuses & Free Spins section explains how to read those terms. A free spins bonus inside a slot is something else: a feature round you trigger during play, covered by your original stake.

Free play works through demos. Every game review on FAQsino includes a demo where the studio allows it, so our game reviews are the place to try games for free. A demo uses play money: nothing you win has any cash value, and nothing can be withdrawn. UK-licensed casinos must verify your age before you play free versions, and a demo may run a different RTP version from your casino.

New games arrive constantly, and each game developer sets its own release date and pace. NetEnt had released 13 new slots by mid-October 2026, Hacksaw says it now makes five games a month in-house, and Pragmatic Play releases up to eight a month. Our reviews list recent releases with their published RTP and max win, so read the review before chasing a new title.

Crypto Casino Game Developers: The Facts

Some casino game developers build games that crypto casinos use, and some of those games are sold as “provably fair”. In general terms, it works like this: before you bet, the game shows a cryptographic hash of a result it has already fixed; after the round it reveals the inputs, so you can recompute the hash and confirm the result wasn’t changed. That proves the outcome was decided in advance. It doesn’t prove what the game’s RTP is, and it isn’t a substitute for the lab-certified RNG that regulators require.

BGaming, which began inside SOFTSWISS, offers provably fair verification on selected games and explains the method on its own site; of the game pages we read, Plinko is the one that says so. Paying in crypto doesn’t change a game’s maths. It’s a payment question: the UKGC rates cryptoassets a high-risk payment method, which licensees can accept only if they tell the Commission and show they can meet anti-money laundering and social responsibility duties. The Commission also notes that crash games appear at crypto casinos it doesn’t license.

A casino that takes crypto still needs a licence that covers you. We don’t list or promote unlicensed crypto casinos.

Casino Game Developers vs Video Game Developers

If you were looking for a video game developer, a mobile game developer or an immersive game developer in the wider games industry, this page isn’t about that. Casino game development shares skills with video games (art, animation, sound, HTML5 for phones), but the product is a regulated gambling product:

• Licensing: in Great Britain, software used for remote gambling, such as random number generation and bet settlement, counts as gambling software and needs a licence. Ordinary video-game software doesn’t.
• Certified maths: a real-money game needs an independently tested RNG and RTP before release, and casinos monitor its live performance afterwards.
• Design rules: UK online slots must allow at least 2.5 seconds between game cycles, can’t offer turbo or slam-stop features, and can’t celebrate a return that is equal to or less than your stake.
• Autoplay and stakes: autoplay was banned for online slots from October 2021 and for all online casino games from January 2025. Since 2025, online slot stakes have been capped at £5 per game cycle (from 9 April), or £2 for players aged 18 to 24 (from 21 May).
• Real-world value: the UKGC says in-game items that can be converted to cash gain real-world value, and gambling with them needs a licence.

Mobile matters in both worlds, and web casino game developers build for browsers and phones alike. Evolution says 73% of its 2025 revenue came from mobile play, and ELK Studios designs its slots for one-handed portrait play.

Casino Game Development: What Supplying Games Legally Takes

Some readers arrive looking to hire casino game developers, to find a casino game software developer or to compare casino game development companies. We don’t offer development services, we don’t rank the top casino game development companies and we don’t recommend any online casino game development company or casino game development studio for hire. The regulated requirements are public, though, and they explain why casino game app development is a different job from building a casual game:

1. A maths model. Mathematicians design and balance the RTP, volatility and features, and regulators and casinos judge the live game against those theoretical figures.
2. Independent certification. An approved lab tests the RNG and the maths before release, market by market.
3. A casino game supplier licence in each market. A UK gambling software licence, an MGA critical gaming supply licence, Swedish and Danish supplier licences, AGCO registration in Ontario and US state licences are all separate. Hacksaw held 16 at the end of 2025.
4. Integration. Games run on a remote gaming server and reach casinos directly or through aggregators.
5. Market-specific builds. Spin speed, stake limits, autoplay and jackpots differ by country, so one game may need several versions.

Certification alone is a real cost: Hacksaw capitalised €2.8 million of external certification services in 2025, up from €1.5 million in 2024. Any offer of casino game development solutions that skips licensing and certification produces a game that licensed casinos in markets such as Great Britain can’t legally use.

Game Developer Jobs at Casino Studios

Casino game developers hire many of the same people as video game studios, plus specialists you won’t find elsewhere. Evolution had 22,475 employees at the end of 2025 and says it works from more than 40 locations; its careers site groups roles under Studio Operations, Engineering, Business Support, and Product and Sales. Hacksaw grew from 141 to 254 employees during 2025, hiring more than 110 people, mainly in game development, compliance and commercial roles.

The most casino-specific job is the game mathematician. In October 2026 Evolution was advertising a Game Mathematician role at its NetEnt studio in Stockholm, asking for a degree in maths, physics, engineering or computer science plus programming skills, and Thunderkick listed a Senior Mathematician post to design, prototype and balance slot maths that meets each market’s rules.

Other current roles include compliance heads and risk analysts, and Evolution has also advertised backend game developer posts. Studios advertise game developer jobs on their own careers pages; we don’t list them. We’re hiring too, but for FAQsino itself.

How FAQsino Rates Casino Game Developers

Every studio review carries a Trust Score from 0 to 10, calculated automatically as the average of six category scores. Nobody types the total in: it updates whenever a category score changes, which is why live scores appear in the compare table rather than in this text.

1. Game Library Depth: the size, range and quality of the catalogue.
2. RTP Transparency: whether the studio publishes RTP, volatility and max win, and whether lower RTP versions exist that it doesn’t disclose.
3. Licensing & Trust: licences confirmed on regulators’ registers, disclosed ownership and enforcement history.
4. Gambling Experience: how the games play overall, from features to presentation, not only live casino.
5. Mobile Performance: how well the games work on phones and tablets.
6. Innovation: original mechanics and formats.

Each review is researched from primary sources first (company sites and filings, regulators’ registers and decisions), then named trade press. We label company claims as claims, date every check, and set scores so they compare fairly across all 15 reviews. This page was last fully checked on 18 October 2026.

What We Couldn't Verify

• Which RTP version your casino runs. Casino game developers that list several versions don’t publish which casinos use which, and we found no regulator document that lists them. Only the game’s own rules screen tells you.
• Approved test houses. We didn’t confirm the UKGC’s list of approved test houses for this guide, so we don’t call any lab UKGC-approved. Lab names above are as the game developers state them.
• Owners. Play’n GO and BGaming don’t publish their owners, and Pragmatic Play doesn’t name the individual shareholders behind its Veridian-led group.
• Founding dates. Play’n GO’s is disputed (2005 or 2006), Yggdrasil’s is given once as 2012 rather than 2013, and Pragmatic Play’s c. 2015 comes from its company footer.
• Company figures. Game counts, live-table counts and release rates are mostly the game developers’ own. Games Global’s figures come from a 2024 draft IPO filing, and Novomatic’s 500+ games is a 2019 figure.
• Regulator actions. The table lists actions as recorded by regulators, a court and trade press in our reviews; the Yggdrasil fee is from trade press only. We don’t list lawsuits or allegations.
• Market size. Industry estimates use different scopes and dates, so we don’t combine them.

The Bottom Line on Casino Game Developers

The studio behind a game decides its maths, its features and how much it tells you. The casino decides which version you play and holds your money. Choose games from game developers licensed where your casino is licensed, favour those that publish RTP, volatility and max win, and check the RTP in the game’s rules before you play.
