The Money Train series by Relax Gaming is widely considered the gold standard for high-volatility, feature-buy slots. With the release of Money Train 4, touted as the “final installment” in the saga, many players are wondering if the new upgrade truly tg88 army renders its predecessor, Money Train 3, obsolete. Both games offer an adrenaline-pumping experience, but they differ significantly in their mechanics, math models, and overall “feel.” In this comparison, I will break down the key differences to help you decide which train is worth catching.
Core Specifications and Math Models
At a glance, both games are “monsters” in terms of potential, but Money Train 4 pushes the boundaries of what is possible in a modern slot. While Money Train 3 was already a heavy hitter with its 100,000x max win, the fourth installment increases that potential by 50%.
| Feature | Money Train 3 | Money Train 4 |
| Max Win | 100,000x Stake | 150,000x Stake |
| RTP | 96.10% | 96.10% |
| Volatility | Very High | Very High (Extreme) |
| Grid Size | 5×4 | 6×6 |
| Win Mechanic | 40 Fixed Paylines | Scatter Pays (8+ Symbols) |
| Release Date | September 2022 | September 2023 |
The most immediate change is the move away from traditional paylines. Money Train 4 utilizes a Scatter Pays mechanic on a larger 6×6 grid.1 This means you no longer need symbols to follow specific lines; you just need 8 or more matching symbols anywhere in view to trigger a win. This makes the base game of the fourth version feel much more modern and dynamic compared to the structured 40 lines of the third.
The Bonus Round: Money Cart Evolution
The heart of every Money Train game is the Money Cart Bonus.2 While the fundamental “Hold and Win” mechanic remains the same (3 respins that reset when a symbol lands), the variety of modifiers has expanded.
What Stays the Same?
The classic “holy trinity” of bandits—the Collector, the Payer, and the Sniper—return in both games.3 Their persistent versions remain the most sought-after symbols, as they apply their effects on every single spin for the remainder of the bonus.
What is New in Money Train 4?
Money Train 4 introduces several high-impact modifiers that weren’t present in its predecessor:4
- The Arms Dealer: This character takes up to four standard bonus symbols and converts them into special feature symbols.5
- The Unlocker: Instead of the grid expanding automatically when you fill a reel (as in MT3), the Unlocker symbol specifically grants you more rows, up to a maximum of four additional rows.6
- The Upgrader: This powerful symbol takes up to three existing feature symbols and turns them into their “Persistent” counterparts.7
- The Reset Symbol: A simple but effective addition that resets the spin counter back to three and stays on the board, potentially allowing for even longer sessions.8
Base Game Mechanics and Respins
I’ve always found the base game of Money Train 3 to be a bit of a grind. It features a Respin mechanic where a symbol is randomly chosen to be sticky, and you keep spinning as long as you land more of that symbol.9 It’s okay, but it can feel repetitive.
In contrast, Money Train 4 revamps the base tg88 slot game game respin.10 Because it uses Scatter Pays, the respin feels more like a “cluster” event. Furthermore, the fourth installment includes Multiplier symbols in the base game that can appear during respins to boost your win before you even reach the bonus.11 It feels like Relax Gaming listened to player feedback and tried to make the “wait for the bonus” less punishing.+1
Visuals and Theme: Cyberpunk vs. Post-Apocalyptic
The aesthetic shift between the two games is subtle but noticeable.
- Money Train 3 has a distinct “Cyberpunk/Sci-Fi” vibe.12 The train is a glowing blue, high-tech machine, and the characters look like they stepped out of a neon-lit future.13 It’s sleek and polished.+1
- Money Train 4 leans harder into a “Post-Apocalyptic/Industrial” aesthetic.14 It’s grittier, darker, and feels more “final.” The music is more orchestral and epic, signaling that this is the grand finale of the bandits’ journey.15+1
Conclusion: Which One Should You Play?
Choosing between Money Train 3 and Money Train 4 often comes down to your tolerance for volatility and your preference for game mechanics.
Choose Money Train 3 if:
- You prefer traditional paylines over scatter pays.
- You find 100,000x to be more than enough potential.
- You enjoy the blue, high-tech cyberpunk aesthetic.
Choose Money Train 4 if:
- You want the absolute highest win potential (150,000x).16
- You prefer Scatter Pays and a larger 6×6 grid.17
- You want the most “feature-heavy” version with over 20 different modifiers.18
- You enjoy the epic, “end of an era” atmosphere.
Personally, I find Money Train 4 to be the superior game purely for the Scatter Pays mechanic. It makes every spin in the base game feel more engaging. However, Money Train 3 remains a masterpiece and often provides a slightly more “stable” (if you can call it that) high-volatility experience.
