Money Train 4

Welcome to the Off-World Frontier

Imagine stepping into a scorched desert, but not the kind you’ve seen in a classic Western. Think dusty red sand, skies stained blue with heat, and a metal beast of a train, all gleaming steel and jagged weaponry, right in the middle. Money Train 4 takes the series way beyond the Wild West—this is dystopian sci-fi, tribal chiefs and robot outlaws, under a sun that never lets up.

You’re dropped onto what feels like another planet after some world-shattering event. Skulls and tech are scattered everywhere, the soundtrack slams cinematic beats and war machine growls, and Relax Gaming spares no expense on visuals or atmosphere. If you’ve spun through the last Money Train slots, you’ll know the music’s always tense, and Money Train 4 is all-in on that movie-level intensity.

This is Relax Gaming’s send-off to what might be their most iconic series—a huge, final clash riding six massive reels. Released in 2023 and confirmed as the finale, it’s not just a celebration of what came before—it’s the wildest ride in the franchise.

How Money Train 4 Really Plays

Money Train 4 opens on a big, expanded 6x6 grid. No fixed paylines—this slot uses a scatter pay system. If you catch at least eight of the top two paying symbols (or 10 of any others) anywhere on the reels, you get paid. It’s a break from old-school lines, designed for chaos and excitement.

The action seriously heats up with a Tumble mechanic. Win with a combo and those symbols vanish, leaving new ones to crash down and maybe start a chain of wins. The betting range starts at €0.10 a spin, which welcomes just about everyone, though the high volatility means those wins can be a stretch apart. If you’re used to those reliable little wins, brace yourself—this game is all-or-nothing at times.

The Return to Player (RTP) sits at 96.10%. That’s competitive, slightly above what you’ll find in the average slot. But the volatility? Very high—officially a 5 out of 5. That means some sessions will feel quiet, but suddenly you hit a massive feature or a surprise respin and everything blows up (in the best way). Autoplay and turbo spin are straight-forward, for those who like to set it and let it ride.

Chasing Wild Features (Without Wilds)

Here’s a twist: Money Train 4 slot ditches the traditional Wild symbol completely. It makes up for it with more features and modifiers than any slot in the series—over 20, just in the bonus alone. No matter how you feel about standard Wilds, you probably won’t miss them here.

At the core, Money Train 4 is about its bonus mechanics. After any spin, the Respins feature can randomly trigger. The most frequent symbol sticks, the rest respin. Multiplier symbols show up during respins. As long as fresh sticky symbols or multipliers land, the round keeps going. It ends only when nothing new lands. This comes out of nowhere and can drop some serious surprises into base game play.

All Eyes on the Money Cart Bonus

It’s not a Money Train game without the infamous Money Cart Bonus. Trigger it with three or more Bonus symbols. Suddenly, the screen shifts to nighttime — fires flicker, rain lashes down, and a battered train sets the stage. The grid scales back to 6x4 to start, but as you fill rows with symbols, it can expand as wide as 6x8. The bigger the grid, the more chaos — and the crazier the prizes.

You get three spins to start, reset any time a symbol lands. But it’s the range of modifiers that sets Money Train 4 apart. There are Collectors, Snipers, Payers, and more — nearly every symbol comes with some unique twist. Persistent modifiers stick around between spins, unlocking brutal combinations. There’s an Unlocker to add new rows, an Arms Dealer to transform symbols, and even a Necromancer that revives previously used modifiers.

Some of these features have never been seen before, and when they start interacting, especially with rows expanding and multipliers stacking, it’s easy to see how those massive 150,000x wins are technically possible (though don’t bank on it — they’re called ‘max wins’ for a reason).

And yes, for the impatient or those hunting a real rush, there’s always a bonus buy option tucked into the controls, letting you skip the wait.

What the Symbols Are Worth

The paytable keeps close to the sci-fi Western vibe. The top-paying symbols are a lineup of dangerous characters—think sheriff, outlaw, cowgirl, Native chief—all oozing attitude and grit. Pull eight or more of the two highest-paying symbols and you’re in the win zone. Lesser-paying symbols are card suits—clubs, spades, hearts, diamonds—filling in the space but never stealing the show.

While there aren’t standard Wilds, Bonus (or Scatter) symbols are where your focus should be. Land enough and you’ll set the stage for all those feature-packed moments discussed above. Visually, symbols pop off the reels—especially when wins trigger their quick, punchy animations or when nighttime falls during the bonus.

How to Get Spinning (and What to Expect)

Setting your bets is straightforward. Hit the menu (three stacked lines), adjust your stake with simple ‘+’ and ‘–’ toggles, and you’re ready. The spin button stands out clearly. Want to sit back? Flick on autoplay, and the game will take care of the rest.

The paytable is always a click away through the same menu—worth a look before you start, especially if you’re chasing certain bonus symbols.

For anyone trying the Money Train 4 demo or taking a shot at Money Train 4 free play, expect the early spins to feel like a slow simmer. Once features trigger, especially that first Respins burst or the Money Cart bonus, things get wild quickly. Don’t be surprised if you find yourself wanting to reload for another round.

Stacking Up Against the Money Train Series and Others

If you’ve played Money Train 2 or 3, this slot will feel like a next-gen sequel — bigger grid, more features, and a much higher max win (150,000x, easily one of the wildest on the market). The base volatility will feel familiar, but the scatter pays and expanded modifiers add even more unpredictability.

Fans of other Relax Gaming slots—like the Money Cart spinoffs—will be right at home here, though the leap in design and pace is clear. If you’ve enjoyed chaotic slots with Hold and Win (or Hold and Spin) styles, or anything with persistent modifiers, this is their ultimate evolution.

For players who love a thematic journey (thinking along the lines of Dead or Alive 2 or those deep, story-rich ELK Studios games), Money Train 4 offers a layered experience that’s endlessly replayable.

Is Money Train 4 Worth Hopping On?

Money Train 4 is not just a strong finish for a franchise—it’s stacked with spectacle, real volatility, and bonus features that genuinely feel different every time. The audiovisual polish rivals top-tier video games, and while the slot is ruthless at times, the chance for something massive is always hanging there in the background.

If the sci-fi Western vibe and wild volatility speak to you, or you just want something with a bonus feature you’ve never seen, this is the right stop. New players should give Money Train 4 free play a spin first to get a feel for the ride.

For those hunting similar adrenaline rushes, check out the earlier Money Train slots (especially Money Train 3 for a great intro), or go for high-volatility hits like Dead or Alive 2. If you’ve caught the fever for mad features, the Money Cart series from Relax Gaming is a natural follow-up. Heads up: it’s easy to get hooked on the chaos.
