What Relax Gaming does well
The Money Train series is the reference point for persistent-symbol bonus rounds — a respin grid where collectors, payers and multipliers interact and the round can escalate for a very long time. Money Train 4 caps at 100,000x, and unlike most headline caps it is reachable through mechanic stacking rather than a single lucky symbol.
The Silver Bullet and Powered By programmes matter as much as the games. Relax distributes and hosts dozens of smaller studios, which is why a mid-size casino can carry hundreds of niche titles without integrating each one.

RTP, volatility and what to check before you spin
- Money Train titles run around 96.1% with return heavily concentrated in the bonus round — base-game play is close to filler.
- Bonus buys are tiered, and the highest tier is a genuinely different maths model rather than a more expensive version of the same round.
- Dream Drop is a network progressive layered onto participating games; the jackpot contribution comes out of the base RTP, so participating versions run slightly leaner.
- As an aggregator, Relax also hosts third-party games whose RTP settings are chosen by those studios, not by Relax.
Money Train 4 is the rare 100,000x cap that is a mechanic outcome rather than a marketing number.
How to do this
How to check the real RTP of a Relax Gaming slot
- Open the game and tap the menu or 'i' icon to reach the paytable info panel.
- Scroll to the game rules footer — the live RTP for that casino's configuration is printed there, not on the lobby tile.
- Compare it with the studio default in the table above. If it is more than half a point lower, play the same Relax Gaming title somewhere else.
- Note the volatility rating and set a loss limit before your first spin.
Who Relax Gaming suits
High-variance players who prefer a bonus round with visible state and escalation over a spin-and-hope free-spins mode. Also the studio to know if you care about which niche games your casino actually carries.
Our take
Relax gets less credit than it deserves because half its value is infrastructure. The Money Train line alone would justify the score.
Verdict
Relax Gaming combines one of the best bonus-round designs in slots with the aggregation layer that keeps the indie end of the market alive. Consistent RTP, tiered buys with real design differences, and a flagship series that has improved with each entry.
