Money Train 3 (Relax Gaming) review: a 100,000x ceiling, GB caveats and all
The big-ceiling proposition
Money Train 3 is Relax Gaming's flagship high-volatility slot, and its calling card is a 100,000x max win — double the ceiling of Money Train 2 and among the largest in the entire market, rivalled by few outside its own family. For players chasing a life-changing multiplier rather than steady returns, it sits at the extreme end of the risk/reward spectrum. The 96.10% base RTP is merely average; you are not playing this for its edge, you're playing it for the tail.
That distinction matters. A high max win and a high RTP are different things, and Money Train 3 has only one of them. Its return is concentrated almost entirely in the Money Cart bonus, so the base game can feel barren for long stretches. This is the textbook "huge ceiling, brutal variance" slot — the opposite of a grinder like Ugga Bugga.
The Money Cart bonus
The heart of the game is the Money Cart hold-and-win bonus, triggered by landing enough bonus scatters (or, where legal, by buying in). The reels lock to a respin board populated by 13 modifier symbols — collectors, payers, multipliers, persistent symbols and resetters — that interact to build the win. It's a rich, well-designed feature with genuine depth, and the interplay of modifiers is what produces the rare five- and six-figure-multiplier results. The wild-west/steampunk theme is slick and atmospheric.
What we like — and don't
Strengths
- 100,000x max win — among the very highest in the market
- Superb, deep Money Cart bonus with 13 modifiers
- Slick wild-west/steampunk presentation
- Genuine big-hit potential for thrill-seekers
Weaknesses
- Base RTP of 96.10% is only average — not a high-RTP slot
- EXTREME (5/5) volatility — long, dry, expensive stretches
- Feature-buy (and its 96.50% RTP) banned for UK players
- Most players will never see the big wins it's famous for
Verdict
Skip if: you want a high RTP or a steady ride — at 96.10% with 5/5 volatility, this is neither.
Money Train 3 is a brilliant slot for exactly one job: chasing an enormous, rare win through a best-in-class bonus. As a high-RTP pick it doesn't belong in the conversation — 96.10% is ordinary, and the volatility is punishing. We include it because its 100,000x ceiling is genuinely notable and because the GB feature-buy caveat is widely misreported. Go in clear-eyed: this is a high-ceiling thrill, not a low-edge grind, and you should only play it with money you're fully prepared to lose. If you do want to play it, a casino that prints per-game RTP on its thumbnails — like our top pick in the Mr Vegas review — lets you confirm the exact Money Train 3 build before you spin.
