Relax Gaming: the Money Train studio and content powerhouse

Two businesses in one

Relax Gaming, founded in 2010 with bases in Malta and Sweden, wears two hats. It is a well-regarded in-house slots studio in its own right, and it is a large content aggregator whose platform distributes games from hundreds of partner studios to operators. Its "Powered By Relax" and "Silver Bullet" programmes help smaller developers reach the market. For UK players the aggregation side works behind the scenes, but the in-house games are the reason to recognise the brand, and they appear across the operators in our casino comparison.

The Money Train series

Relax’s defining creation is Money Train, a Western-heist slot whose bonus round became one of the most famous features in modern slots. Money Train 3 and its predecessor Money Train 2 built enormous followings on the strength of a persistent-symbol bonus where cash values, collectors, multipliers and payers combine to chase a top payout worth tens of thousands of times the stake. The series is central to the studio’s identity and among the most-streamed slots around. You can try titles from the range in our free games area.

The in-house catalogue

Beyond Money Train, Relax has produced fan favourites like Temple Tumble, a cascading Megaways-style slot, and Marching Legions, alongside a steady stream of well-made originals. The in-house team has a reputation for strong maths and clean design, and its games tend to sit at the enthusiast end of the market. While the aggregation business gives Relax scale, it is this original output that has earned the studio genuine respect among players who follow who makes the games they play.

RTP and volatility

Relax’s flagship in-house slots are firmly high-volatility, with the Money Train series in particular built around a rare, enormous bonus payout rather than frequent wins. Return to player generally sits around 96% at the default, though the feature-buy versions and configurable options mean the paytable is the reliable reference. Feature buys, a big part of how many players triggered the Money Train bonus, are unavailable in Great Britain under the UK Gambling Commission’s October 2023 ban, so UK players reach the round through normal spins.

Silver Bullet and partner content

A distinctive part of the Relax business is its partner programmes, which bring third-party studios onto its platform and, in effect, incubate new talent. Games from these partners reach a wide audience they might otherwise struggle to access. For players this means a single supplier relationship can deliver an enormous and varied catalogue, though the quality naturally varies across so many developers. As with any aggregator, knowing which studio actually built a given game tells you more than the Relax badge alone.

Where to play Relax Gaming in the UK

Relax content, both in-house and aggregated, is carried by a large number of UKGC-licensed casinos. As always, pick the operator on its licence and safeguards, including GAMSTOP, age verification and the credit-card ban. Our casino reviews highlight sites with the fullest Relax range, especially the Money Train games, and recent launches appear under new casinos. Given the high volatility of the flagship titles, the free demos are a sensible first stop.

The verdict for UK players

Relax Gaming punches above its weight, combining a genuinely respected in-house studio with the reach of a major aggregator. The Money Train series alone has earned it a place in the modern slots canon, and Temple Tumble and its other originals hold up well. The volatility is steep and feature buys are off the table in the UK, so the games demand patience. But for high-variance thrills and a vast catalogue accessed through one supplier, Relax is a heavyweight of the UK market.
