Money Train 4 launched on September 20, 2023, and it's the slot with the highest max win across the entire market, all providers combined: 150,000x total stake. That's ahead of NoLimit's headline hits (Tombstone R.I.P.'s theoretical 300,000x, which is essentially unreachable in practice), the top Megaways titles, and every Hold & Win slot out there.
TL;DR
- Relax Gaming slot, September 2023, a sequel to the legendary Money Cart line. Format 6x6 Scatter Pays (pay anywhere). RTP 96.1%.
- High volatility (5/5), MAX 150,000x market record, a reassuring hit rate of 20.14%.
- Streak respins (cumulative multipliers) plus a Money Cart Bonus with 20+ modifier symbols, including the new Upgrader (regular to persistent).
- Standard 100x bonus buy or 500x with a pre-loaded persistent symbol. Min bet €0.10.
Max win 150,000x — market record
| Slot | Max Win |
|---|---|
| Money Train 4 (Relax) | 150,000x 🏆 RECORD |
| Tombstone R.I.P. (NoLimit) | 300,000x theoretical (never hit in practice) |
| Mental (NoLimit) | 66,666x |
| Royal Joker H&W (Playson) | 21,150x |
| Bonanza Billion (BGaming) | 15,000x |
150,000x at a €1 stake = a €150,000 theoretical maximum jackpot. At €6 (max bet) that's €900,000. The absolute practical record on the market.
Money Cart Bonus Round — the cult mechanic
This is the bonus round that made the Money Train franchise legendary. Here's what goes into it:
- Triggered by 3+ scatters
- A fully self-contained bonus round (not just free spins)
- 20+ distinct modifier symbols: Collector, Payer, Sniper, Necromancer, Persistent, Reset, Bonus, Wave Sniper, Upgrader (new), and more
- Every symbol has its own effect, plus complex interactions
- Multipliers and persistent symbols accumulate, driving exponential potential
The 2023 innovation: the Upgrader converts regular symbols into persistent versions — a change that radically reshapes the endgame of the bonus.
Bonus buy — 100x or 500x
| Tier | Cost | Guarantees |
|---|---|---|
| Standard | 100x stake | Money Cart Bonus triggered |
| Premium | 500x stake | Money Cart plus a pre-loaded persistent symbol |
⚠️ Bonus buy is banned in the UK. 500x is the direct path to big wins, but it costs 5x more.

FAQ
What is Money Train 4's RTP?
Official RTP: 96.1% (adjustable per operator). Check via the in-game "i" button.
How do you reach the 150,000x max win?
The combo: a Money Cart Bonus running for an exceptionally long session, plus cumulative multipliers via Persistent symbols, the Upgrader converting regular symbols into persistent ones, and cascading explosions. The probability is extremely low, but it's the only path to the market record.
100x or 500x bonus buy — which should I choose?
100x is the standard entry point. 500x comes with a pre-loaded persistent symbol (a direct path to big wins, with boosted RTP). For a modest bankroll: go 100x. To chase the 150,000x: 500x is mathematically EV-positive.
Is Money Train 4 available at real-money casinos?
Yes, at most of the top-rated crypto/anonymous casinos in our comparison that carry Relax Gaming.
