Relax Gaming Casinos & Slots 2026

Relax Gaming is one of the most influential studios in modern online slots, and it is a name high-variance players know by heart. The studio built its reputation on a single, era-defining franchise: the Money Train series. Titles like Money Train 2 and Money Train 3 turned the "respin / collect" bonus into a cultural phenomenon, and Money Train 2 in particular became legendary for its ferocious max-win potential. Alongside that flagship line sit cult favourites such as Temple Tumble, Hellcatraz and Iron Bank, all of which share the same trademark Relax DNA: clean design, brutal volatility and bonus rounds worth chasing.

This page explains who Relax Gaming actually is, how its dual identity as both a game studio and a content-aggregation platform works, which of its slots are worth your time, how its software and fairness systems operate, and where you can play safely. The casinos listed in the sidebar all carry a strong line-up of Relax Gaming titles, so you can jump straight from research to a real spin.

Who is Relax Gaming?

Founded in 2010 with Nordic and Baltic roots

Relax Gaming was founded in 2010 and is headquartered in Sliema, Malta, with development teams rooted in the Nordic and Baltic regions. In its early years the company focused on poker and bingo network technology, but it gradually evolved into a slot studio and content distributor. That technical heritage matters: because Relax grew up building robust platform infrastructure, it was unusually well placed to combine its own award-winning slot development with a powerful delivery system for other studios' content. Today it is regarded as one of the premium names in the high-volatility space.

The aggregation platform and the Kindred acquisition

Relax Gaming is not just a slot studio — it is also a major content-aggregation platform. Through its "Powered by Relax" partner programmes (commonly known as Silver Bullet and Gold), the company distributes thousands of games from carefully selected third-party studios through a single integration, alongside its own titles. This dual model — making acclaimed in-house slots while also acting as a one-stop content hub for operators — is a big part of why Relax content appears in so many casinos. In 2021, the studio was majority-acquired by the Kindred Group, one of the largest listed online-gambling operators in Europe, which gave Relax even greater scale and reach while it continued to operate as a distinct creative brand.

The Best Relax Gaming Slots You Have to Play

Relax Gaming's catalogue is built around a handful of cult-status releases. These are the titles players hunt for by name — slots defined by aggressive volatility, satisfying bonus mechanics and the kind of max-win potential that draws streamers and high-rollers alike.

Money Train 2 is the undisputed flagship. Its Wild-West theme and the now-iconic respin "collect" bonus — where cash values, multipliers and special symbols accumulate over locked respins — produced a documented max win of roughly 50,000x the stake, an outcome that cemented Relax's reputation in the high-variance community. If you only try one Relax Gaming slot, start there, then work through Money Train 3, Hellcatraz and Iron Bank.

Relax Gaming Software & Technology

Behind the polished artwork sits one of the most respected technology stacks in the business — and because Relax is both a studio and a platform, its infrastructure is built to serve at industry scale.

RNG and fair maths

Every Relax Gaming spin outcome is decided by a certified Random Number Generator (RNG). Spins are independent — a previous result never influences the next — and the long-term return is governed by the published RTP rather than anything the player or casino can alter mid-session. The studio's reputation rests on transparent, lab-verified maths, even on its most extreme high-volatility releases.

Testing and certification

Relax Gaming holds licences in multiple regulated markets and its games and RNG are tested by independent laboratories before release. As a Kindred Group company, it operates within one of the most established compliance frameworks in the industry, which is why you will find its content inside casinos licensed by major authorities. That regulatory backing is what allows such aggressive, high-stakes maths models to run inside properly supervised environments.

HTML5, mobile and security

Every modern Relax Gaming title is built in HTML5, so the games run natively in the browser on iOS and Android phones, tablets and desktops with no app or download. Crucially, Relax also runs a full aggregation platform that delivers both its own titles and the content of its "Powered by Relax" partner studios through a single integration — the same pipeline that powers its Dream Drop progressive jackpot, a network jackpot built across participating Relax games. Game data is delivered over encrypted connections by the licensed operator hosting it. If you mainly play on a phone, see our guide to the best mobile casinos.

Relax Gaming RTP & Volatility

Relax Gaming slots typically target an RTP around 96%, though some titles — including certain Money Train releases — have appeared in higher-RTP configurations. What defines the studio is volatility: most of its headline slots are high or very high variance, with the Money Train line in particular famous for an enormous qualitative max-win ceiling that can reach tens of thousands of times your stake on the rarest, biggest hits. The table below gives an at-a-glance comparison of popular releases.

RTP values are indicative only and can vary between operators, as some Relax titles ship in multiple RTP versions. Always confirm the actual payout percentage in the game's own info panel before you play.

What Makes Relax Gaming Slots Special?

High-volatility design and bonus mechanics

The single biggest selling point of a Relax Gaming slot is the bonus round. The studio practically defined the modern "respin and collect" feature with the Money Train series — a mechanic where cash symbols, multipliers and special tiles accumulate across locked respins toward a potentially explosive total. That design philosophy runs through the whole catalogue: long, patient base games punctuated by rare but devastating bonus hits. Many Relax titles also offer a Bonus Buy option that lets players pay a multiple of their stake to jump straight into the feature — a tool built for thrill-seekers who understand the risk that comes with very high variance.

Licensing and trust

Relax Gaming operates under recognised licences across regulated markets and, as part of the Kindred Group, sits within a robust, publicly accountable compliance framework. Its games and RNG are independently certified, and its aggregation platform is held to the same standards because it distributes content to licensed operators worldwide. On GamblersPeak we only list casinos that hold a recognised licence, so any Relax Gaming title you play through our recommended sites sits inside a properly regulated environment — with availability depending on your region.

Relax Gaming vs the Competition

Relax Gaming sits firmly at the premium, high-volatility end of the market, so it is most often compared with the other studios chasing big-win thrills.

• Relax Gaming vs Nolimit City: Both are darlings of the high-variance community, but Nolimit City pushes darker, more provocative themes and its trademark x-mechanics, while Relax leans on the cleaner, more universally accessible "collect" bonus that made Money Train famous. If you want extreme volatility without the grimmest themes, Relax is the smoother entry point.
• Relax Gaming vs Hacksaw Gaming: Hacksaw favours snappier, arcade-style slots and instant-win games beloved by streamers; Relax delivers deeper, feature-driven bonus rounds and also acts as an aggregation platform that distributes other studios' content. For substantial, structured bonus mechanics, Relax has the edge.

In short: Relax Gaming is the studio you turn to when you want the iconic Money Train respin thrill, premium production values and a catalogue that doubles as a gateway to dozens of partner studios.

Our Verdict on Relax Gaming

In our view, Relax Gaming is one of the most important studios of the modern slot era — a developer that not only created a genre-defining franchise in Money Train but also built the platform that puts its peers' games in front of millions of players. Its slots demand a tolerance for high volatility, but the payoff is some of the most satisfying bonus rounds in the business. If you want big-win potential with cleaner themes than its rivals, Relax is essential.
