Money Train 4 Features

Regular wins come courtesy of a scatterpay system and this means there's no need to follow any win lines and there are basically no rules. As long as you have a minimum of 8 matching symbols anywhere on the grid, you will win a prize. The biggest payers are the 4 main characters with wins up to 1000x for 36 matching symbols. The lower-paying icons are made up of Card symbols.

On the features front, what we have here is almost a carbon copy of Money Train 3 except things look slightly different on this 6x6 grid compared to the 5 reels from before. 

It all begins with the base game respins that can trigger at any point with one of the regular symbols being selected to enjoy some kind of higher status. A respin is awarded and any further instances of your special symbol will continue the respin adventure. The only other symbols that can land here are Multipliers, which are totalled up at the end and multiplied by your final win. 

Money Cart Bonus

What every player is looking forward to when loading up Money Train 4 is a chance to relive the Money Cart Bonus round. Relax Gaming has not disappointed its fans and this awesome feature is here again. 

You will need 3 or more Bonus symbols to land to trigger the feature and anyone who has played a game in this series before will recognise the format. It is a respin feature and each time a multiplier amount lands, your respins are replenished back to 3. 

All multiplier values are added to your meter and the potential wins just continue to grow. The most eye-catching thing about this bonus is—and has always been—the set of modifiers that can increase your payouts. The list is long and the results are varied.

Check out the complete list below—your balance will be beaming when they turn up.

Money Train 4 Review

Relax gaming hasn't deviated from its original idea too drastically since the start of this series and it is mainly the theme that gets a bit of a makeover each time. Money Train 4 is a little more Mad Max than Steampunk but there are just as many big guns with dubious-looking characters pointing them all over the place.


As you would expect, Money Train 4 has an epic intro with some of the best graphics you'll ever find on a slot game. As you move into the main arena, some of these graphical elements are just as sharp, but I felt that the grid let the side down a little. The symbols are not quite as well-crafted as previous versions and it didn't quite hit the spot. You can look forward to more dramatic, end-of-the-world-style music to keep your ears busy while you play and mobile devices can easily access all of the above. Look for a strong internet connection and a decent processor on your chosen device as this game can slow things down quite nicely when it wants to.


Not much has changed in terms of gameplay from previous versions and the base game is spent waiting for a respin to trigger. The Money Cart Bonus is a hyped-up version of its former self and while we got quite excited about this the last time around, we have now seen it before—I was hoping for something a little different. The Money Cart Bonus round is just as fantastic as ever but the number of modifiers keeps on growing and it does make me wonder where it's all going to end.

Win Potential

A 150,000x max win is one of the biggest payouts you will ever find on a regular video slot and this keeps it up there as one of the biggest payers of all time. Few others can compete with this figure. The RTP is 96.10% and the volatility is, naturally, very high. Watch out for a fairly low hit frequency which means you will find winning spins around 20% of the time.

Our Verdict

Maybe the biggest problem with any eagerly awaited game is that you build things up too much with all the anticipation. However, Money Train 4 is still a fantastic slot, and if this was the first time I'd ever seen such features and graphics, then surely it would get a 5-star rating all around. But we have been here before and I was hoping for something more/different. Putting that aside, this game is still up there is one of my main recommendations for 2023 and you simply have to give it a shot.

Money Train 4 Slot Preview

We’ve been spoilt for choice up to this point with the Money Train series unveiling a ton of awesome modifiers and features along the way. And rumour has it that a staggering 20 modifiers could be making an appearance this time around. The star of the show has always been the respins game along with the Payer, Collector and other modifiers that help boost the wins. Surely this has to be back in Money Train 4.

While it’s still too early to know if this main feature will make a return, our money says that this is a fairly safe bet.

Stats to look forward to

The official details are being kept a closely guarded secret but what we have seen is a chance that the max payout has been stretched to 150,000x! The original Money Train slot seemed generous at 20,000x, Money Train 2 grew to 50,000x and Money Train 3 maxed out at 100,000x; this figure just keeps on getting bigger and better with each passing release!

The RTP is always around the 96% mark for Money Train slots—with the exception of the Origins Dream Drop game, which fell to 94% due to the Jackpot feature. We can’t imagine that Money Train 4 will stray too far from the rest.

Don’t expect anything less than super-high volatility as this is pretty much a given considering the potentially astonishing max payout of 150,000x.

Sneak peek at the design

It all started on a traditional Wild West wagon, progressed to a trendy steampunk locomotive and then arrived at the futuristic/steampunk blend in the final instalment, Money Train 3. So, what’s next for the series? 

Money Train 4 looks set to be the most futuristic yet with big guns blazing and robots taking charge. It could be a case of Money Train meets the Terminator as we continue with this exciting series.
