Relax Gaming review
Relax Gaming wears two hats, and both are worth understanding. It is a respected slot studio in its own right, behind the cult Money Train series, and it is also a major platform that pipes other studios' games into casinos. This Relax Gaming review looks at what the company actually makes, how its high-variance math behaves, and why one bonus-buy monster, Money Train 3, became a streamer obsession.
Who Relax Gaming is
Relax Gaming is two businesses in one. The first is a slot studio with a sharp, high-volatility identity, best known for the Money Train series and a small but influential catalogue of original games. The second, and arguably the bigger one commercially, is its aggregation platform, which lets casinos plug in games from a long list of partner studios through a single integration. That dual role means you encounter the Relax name in two very different ways, sometimes as a game maker, sometimes as the plumbing behind a lobby.
For players, the studio side is what matters most, and it has a strong reputation. Relax does not flood the market the way the volume houses do. It releases selectively, and its signature games have a distinctive feel: punchy, modern and built around big feature rounds. The catch is the same one that follows most high-variance studios. The excitement comes with real swings, and the headline max wins that make the marketing are rare by design.
What I find interesting about Relax is how the two halves reinforce each other. The original games give the brand credibility and a reason for players to seek it out, while the platform gives it reach and a seat at the table with operators. A casino that signs Relax for the aggregation platform often ends up promoting the Money Train games too, and players who come for Money Train discover the partner studios alongside it. It is a smart model, and for the player it usually means a broader, more varied lobby than a single-studio deal would deliver.
The house style and math
The Relax house style is high volatility with a strong bonus hook. Its signature slots lean on feature rounds packed with persistent symbols, multipliers and collection mechanics, and many offer a bonus buy that lets you pay straight into the action. That makes the games exciting and also swingy, so understanding volatility matters here as much as with any studio. The base game is often a lead-up to the feature, and the long stretches between features are a feature of the design, not a fault.
As with every supplier, the published RTP is only part of the story, because games ship in multiple configurations and the casino picks the version it runs. With high-variance slots that gap matters more, since a couple of points of RTP plays out over long, feature-starved sessions. The bonus buys deserve the same scepticism you would bring to any casino bonus: a buy guarantees you reach the feature, never that it pays. Open the info panel, confirm the version, and treat the max win as a ceiling rather than a target.
The collection and persistence mechanics are the clever part of the Relax design, and they are why the games hold attention through the dry runs. A bonus round where symbols stick and multipliers build feels like progress is being made even when the numbers say otherwise, which keeps you in the seat. That is good entertainment design and a gentle behavioural hook at the same time. Enjoy the build-up for the tension it creates, but keep one eye on your budget, because a feature that feels like it is constantly almost paying out is exactly the kind that encourages one more buy.
Play Money Train 3: the studio's signature slot
If you want to understand Relax in one title, play Money Train 3. It is the latest headline entry in the series that built the studio's cult reputation, a wild-west-flavoured slot built around a dense bonus round with persistent symbols, multipliers and one of the larger advertised max wins in the market. It became a streamer obsession because the feature can build into genuinely spectacular results, and the bonus buy makes those moments easy to chase.
The honest read is that Money Train 3 is a superb high-variance slot and a demanding bankroll game. The enormous ceiling that fuels the highlight clips also means most sessions, and most bonus rounds, end well short of it. Set a firm budget before you open it, treat the bonus buy as a cost rather than a shortcut to value, and enjoy the feature for the spectacle it is. If you like the format, Nolimit City and Hacksaw Gaming chase the same extreme thrill from their own angles.
The Money Train series is also a good case study in how a slot becomes a brand. Each entry kept the core bonus identity while pushing the ceiling higher, so fans of the first game knew exactly what they were getting in the third while still feeling they were buying something new. That continuity is rare and valuable, and it is a big part of why the series outlasts the dozens of lookalikes it inspired. Just remember that a famous name does not change the math: Money Train 3 is as volatile as its reputation suggests, and the budget discipline matters as much here as anywhere.
The platform side
The other half of Relax is the aggregation business, and while it is invisible to most players it shapes what you see in the lobby. By offering its own originals plus a curated set of partner studios through a single integration, Relax helps smaller operators stock a deep, varied catalogue without dozens of separate deals. For the player, the practical takeaway is that a casino carrying Relax often carries a wider, more interesting range as a result. When you assess a lobby's depth, as we suggest in our guide to choosing an online casino, that breadth is part of the value, and the responsible gambling tools should be just as easy to find as the games. 18+.
The verdict
Strengths: a sharp, selective studio with a genuine cult hit, strong high-variance design, and a platform that widens the lobbies it touches. Weaknesses: punishing volatility on the headline games, tempting bonus buys, and the usual RTP versions that vary by casino. Relax Gaming is the quality boutique with a useful platform attached, and its best games earn their reputation. Play them at a casino that runs the full RTP, keep your limits firm, and treat the max win as a story. See where it sits in our casino reviews. 18+.
Relax Gaming FAQ
Is Relax Gaming legit and fair?
Relax Gaming is a licensed, certified supplier whose games use tested random number generators. Fairness sits with the maths and the casino's chosen RTP, so the studio is trustworthy, but its headline slots are high variance, so expect long swings. 18+.
Where can i play Money Train 3 safely?
Play Money Train 3 at a licensed casino that runs the full published RTP and offers deposit and loss limits. Our reviews flag operators that do both, which matters with a slot this volatile and bonus-buy heavy.
Is the money train bonus buy worth it?
A bonus buy gets you into the feature, not a winning one. Over time it does not tilt the math in your favour, and it spends a budget fast. Treat it as paying for a quicker route to the action, not as a value play.
How Relax Gaming compares
Against the field, Relax Gaming is the selective studio with a platform edge. Nolimit City pushes volatility and theme further, Hacksaw Gaming matches its streamer appeal with bolder art, and Pragmatic Play out-produces it many times over. Few rivals combine a cult slot series with a content platform the way Relax does.
