The Money Train Series: An Overview
The Money Train series from Relax Gaming is one of the most celebrated slot franchises in UK online casino. It is also one of the most complicated for UK players to access at the best RTP. This guide covers every version — from the original Money Train through Money Train 4 — with verified UK deployment data.
Money Train 2 (2020) — 96.40% RTP
Money Train 2 launched in August 2020 with a 96.40% RTP and 50,000x max win. It became one of the most-played high-volatility slots in the UK market. The RTP appears to be single-tier — no widely documented reduced version exists for the UK. However, MrQ does not carry Money Train 2 at all. Neither does it carry Money Train 3 or Money Train 4. This is a significant catalogue gap at one of the UK's most-recommended RTP casinos. Players who primarily play the Money Train series should choose a different operator.
Money Train 3 (2022) — 96.10% RTP
Money Train 3 launched in September 2022 with a 96.10% RTP and 100,000x max win. The max win doubled from MT2. The RTP dropped by 0.30 percentage points. This is not a significant reduction — 96.10% is still well above average — but it confirms the pattern of variance inflation without RTP improvement that we documented across Pragmatic Play's franchise sequels.
Money Train 4: The Last Stand (2023) — 96.10% / 94% / 90%
Money Train 4: The Last Stand launched in September 2023 with the same 96.10% top tier but introduced multi-tier deployment for the first time in the series. Three certified configurations: 96.10%, 94%, and 90%. The 90% floor is among the lowest in any major UK slot. The max win increased to 150,000x. This is the first Money Train title where casino choice genuinely matters — a player at a casino deploying the 90% tier loses £100 per 1,000 £1 spins versus £39 at the top tier.
The UK Bonus-Buy Ban and the Money Train Series
The UK bonus-buy ban (effective September 2025) particularly affects the Money Train series. All four titles were designed around the Persistent Collector bonus mechanic, and the Feature Buy option carried a slightly higher RTP than base play on MT3 and MT4. UK players can no longer access this mechanic, making the base-game RTP the only figure that matters.
Relax Gaming's Deployment Trust Profile
Relax Gaming's overall trust profile is strong. CasinoWizard rates Relax Gaming as deploying at the best available tier at most UK casinos including LeoVegas. The provider's catalogue tends toward single-tier or narrow-band deployments, making it one of the safest providers for UK players concerned about hidden RTP reductions. See our Relax Gaming RTP Guide for the full provider breakdown.
Where to Play the Money Train Series
For UK players choosing where to play the Money Train series, the key factors are: does the casino carry the title at all (MrQ doesn't), and for MT4 specifically, which of the three tiers is deployed. Check the in-game info panel on MT4 before committing. If it shows 94% or 90%, switch operators.
The Original Money Train (2019)
The original Money Train (2019) is rarely discussed but runs at approximately 96.20%. It lacks the Persistent Collector mechanic of the sequels and is effectively a different game. Most UK casinos still carry it alongside the sequels.
Gambling can be addictive. Please play responsibly. UK players experiencing problems can self-exclude via GAMSTOP or contact GamCare.
