Money Train 4 Pros & Cons

Money Train 4 delivers classic Aristocrat action with a proven track record. The choice-based free spins and stacked symbols create a good variety, but the RTP and max win won't impress everyone.

👍 Pros
  • 150,000x max win is insane - one of the highest in the industry
  • Over 20 special symbols keep the bonus round unpredictable
  • 96.1% RTP is competitive for this volatility level
  • Expanding rows unlock during bonus add extra win potential
  • Respin feature in base game gives occasional relief
👎 Cons
  • Very high volatility = brutal dry spells between bonuses
  • Max bet capped at $6 disappoints serious high-rollers
  • 1 in 387 spins to trigger bonus means massive bankroll needed
  • No wild symbols in base game limits regular wins
  • Average bonus win only 96.5x - most rounds are underwhelming

Visually, Money Train 4 is on another level. Relax Gaming went cinematic with the graphics and animations, and it shows. The base game happens on a desert planet with huge stone structures and a shiny steel train dominating the screen. During the bonus, things get darker with heavy rain and flaming fires. The art is sharp, the animations are smooth, and even on mobile everything loads instantly. Character designs are detailed - you've got bandits, Native American characters, sheriffs - all rendered in that gritty steampunk style. Relax Gaming uses cinematic graphics and orchestral-style soundtrack that really pumps you up. The soundtrack is intense, dramatic, and fits the high-stakes vibe perfectly. It doesn't get annoying even after long sessions. Performance is flawless on any device we tested. No lag, no stuttering.

Money Train 4 Slot Review: The Last Stand Delivers 150,000x Max Win

Money Train 4 is Relax Gaming's final ride in their legendary slot series, and they went all out. This is a 6x6 grid slot with scatter pays, high volatility, and a max win of 150,000x. Released in September 2023, it's got over 20 special symbols in the bonus round, expanding rows, and that intense steampunk-meets-futuristic vibe the series is known for. We tested Money Train 4 and honestly, it's not for beginners or anyone with a small bankroll. The RTP is 96.1%, but the extreme volatility means you'll burn through your balance fast if the bonus doesn't hit. If you're chasing huge wins and don't mind long dry spells, this could be your game.

Game Overview & Specs

The game takes place on another planet after some earth-destroying event, with a massive futuristic train armed to the teeth. It's wild, cinematic, and way more sci-fi than the original Wild West theme. Good for high-rollers who love bonus features and don't care about frequent small wins. Casual players with tight budgets should probably skip this one.

Symbols & Payouts

Money Train 4 uses scatter pays with 8 symbols split into low-pay card ranks and 4 high-pay character symbols. You need 8 or more of the same symbol anywhere on the reels to win. No wild symbol in this game, but the bonus symbols more than make up for it.

🎰 Sheriff (Red Character) - High Value

The Sheriff in red is one of the top-paying symbols. He's designed with intense detail, full armor and weapons. Landing 36 matching symbols pays between 100x and 1,000x your bet. This symbol appears less frequently than others, but when you fill the screen, the payout is massive. The animation shows him firing weapons when you hit a big win.

🌟 Native American (Orange Character) - High Value

The Native American character in orange is another premium symbol with detailed artwork. Same payout structure as the Sheriff - fill the grid and you're looking at serious money. The design includes traditional tribal elements mixed with futuristic gear. Appears about as often as the Sheriff, so hitting full screens is rare but possible.

👤 Bandit Character 1 - Medium Value

One of the gang members with less payout potential but shows up more frequently. Design features goggles, bandanas, and steampunk accessories. You'll see this symbol fairly often, creating regular scatter wins. Animation is simpler than premium symbols but fits the theme nicely.

👤 Bandit Character 2 - Medium Value

Another gang member with similar mid-tier payout. Appears regularly enough to keep base game wins coming. Design complements the other characters with consistent art style. Not exciting but necessary for keeping your balance steady between bonuses.

💎 Diamond Card Symbol - Low Value

Playing card diamond symbol is one of four low-paying card ranks. Rendered in purple/blue with metallic shine. Pays 0.4x to 1.2x for smaller clusters. Shows up constantly but doesn't pay much. You'll rack up tons of tiny wins with these.

♣️ Club Card Symbol - Low Value

Green-colored club symbol with same low payouts as diamonds. Frequent appearance means you'll see this every few spins. Design is simple but polished. These symbols keep you alive between big hits but won't make you rich.

❤️ Heart Card Symbol - Low Value

Red heart symbol following same pattern as other low-pays. Metallic finish matches game aesthetic. Common enough that you'll land scatter wins regularly. Not exciting but functional for small payouts.

♠️ Spade Card Symbol - Low Value

Black spade completing the low-pay quartet. Most common symbol on the reels. Landing 10+ creates small wins that add up slowly. Simple design but consistent with overall quality of the slot.

🎰 Bonus Scatter Symbol - Special

Landing 3 or more bonus scatters triggers the Money Cart Bonus Round with initial 3 spins. This is what you're really hunting. Golden coin design that lights up the screen when it lands. Probability of hitting 3 scatters is 1 in 387 spins on average. When this shows up, everything changes.

Mobile

Money Train 4 works perfectly on mobile through HTML5 tech. Tested on iPhone, Android, and tablet - zero issues. Graphics look just as good on small screens, and touch controls are responsive. No app needed.

Tips:

Here's what actually helps with Money Train 4:

Bankroll for 400+ spins minimum

Bonus triggers every 387 spins on average, so budget accordingly or you'll bust before seeing it

Use Bonus Buy strategically

The 96.50% RTP on Bonus Buy is better than base game's 96.10%, so if you've got the cash, buying at 500x for persistent symbols can be worth it

Watch for persistent symbols

Landing a persistent symbol from the start gives you better chances of big wins than regular bonus symbols

Base game Respins matter

Don't ignore the random respin feature; it can build decent wins between bonus rounds and extend your playtime

Lower bets on exploration

Max bet is only 0.50 or less until you understand how brutal the volatility is

Conclusion

Final Verdict

4.5 / 5.0

Money Train 4 is for players who want extreme volatility and don't mind going broke chasing the big one. The 150,000x max win is among the highest in the industry, but you'll need incredible luck and a massive bankroll to have any shot at it. The bonus round is genuinely exciting when you finally trigger it, with over 20 special symbols creating unpredictable combinations. But here's the reality - triggering the bonus takes 387 spins on average, and most bonus rounds only pay 96.5x. If you've got a small bankroll, tight budget, or prefer frequent wins, skip this entirely.

It'll frustrate you. This is for high-rollers, bonus hunters with patience, and players who get genuinely excited by extreme volatility. Beginners should absolutely avoid Money Train 4 and start with something friendlier. If you love action movie-style slots with explosive features, this delivers. If you want steady entertainment, it doesn't.

Play Responsibly - 18+ Only

Gambling should be entertaining and fun. Remember that slots are games of chance, and there's no guaranteed way to win. Never gamble more than you can afford to lose, and always set limits for yourself. If you feel gambling is becoming a problem, please seek help immediately.

FAQ - Frequently Asked Questions

How often does the Money Cart Bonus actually trigger in Money Train 4?

On average, you'll trigger it once every 387.4 spins. Yeah, that's brutal. Budget your bankroll accordingly or you won't last long enough to see it.

What's the deal with persistent symbols, and why do they matter so much?

Persistent symbols perform their action on every respin instead of just once. They can substitute for bonus symbols when triggering the round or land during it. Landing one from the start gives you way better chances of big wins because they keep multiplying or collecting on every spin.

Can you actually hit the 150,000x max win, or is it theoretical BS?

The probability of hitting 150,000x is 1 in 94 million spins. So yes it's technically possible, but you'll probably never see it. Focus on the 100x-1,000x range - that's the realistic ceiling for most sessions.

How does Money Train 4 compare to Money Train 3?

Money Train 4 has 20 new features and 150,000x max win compared to MT3's 100,000x. The scatter pays mechanic in MT4 changes base game experience from MT3's paylines, and MT4 has way more special symbols in the bonus. MT4 is bigger, bolder, and more volatile.

What happens when you unlock the expanding rows during the bonus?

Each time you fill a row with symbols, one additional row unlocks - max 4 times. This expands the grid from 6x6 to 6x10, giving you more positions for symbols to land. The symbols that were locked behind those rows reveal and perform their actions, potentially exploding your win.

Is the Bonus Buy worth it, or should you grind naturally?

Bonus Buy increases RTP from 96.10% to 96.50%, so mathematically it's slightly better. Original costs 100x your bet, Persistent costs 500x and guarantees a persistent symbol. If you've got the bankroll and hate waiting 400 spins, buying at 500x for the persistent version is the smart play.

Why doesn't Money Train 4 have wild symbols like normal slots?

Money Train 4 doesn't have wild symbols, but the scatter pays mechanic and the insane number of bonus modifiers more than compensate. Wilds would be redundant when you've got 20+ special symbols doing crazy stuff in the bonus round. The game doesn't need them.

What bet size works best for 5 Dragons?

Start at $0.50-$1.00 per spin with at least $50-$100 bankroll to handle the medium-high volatility. High-rollers can bet up to $125, but the max win potential of around 1,000x doesn't justify huge stakes compared to modern slots with 10,000x+ potential.
