Money Train 4 (Relax Gaming) – Review & Demo Play

Money Train 4 - Slot Overview

Relax Gaming’s Money Train 4 wraps up the series with a 6x6 scatter pays setup, high volatility, and a staggering 150,000x max win. I’m playing on an RTP of 96.10%, with base game Respins and the signature Money Cart Bonus packed with 21 feature symbols. Wins land when eight high pays or ten lows show anywhere, making the grid feel alive even without paylines. It’s off‑world, gritty, and absolutely stacked with modifiers, yet the core loop stays familiar and fiercely entertaining.

Theme and Graphics in Money Train 4

Relax shifts the action off‑world. The base game runs in a dusty, sun‑blasted setting; trigger the bonus and the scene flips to rain, fire, and chaos. The train dominates the frame, steel and menace, giving the slot a proper video game vibe. The soundtrack matches the mood, rising and falling with the action, while the cut‑scene opener sets the stakes before the grid arrives. It’s cinematic without getting in the way of spins.

The 6x6 grid sits between skull‑topped pillars and industrial kit, with slick animations on every hit and respin. Character portraits carry the premium weight, card suits keep the reels ticking, and the UI revision is cleaner than the earlier titles. The whole thing feels like a slot/film hybrid, crisp and punchy, and the transition between modes adds tension before the multipliers and sticky symbols take over. It looks the part and plays fast.

Symbols and Paytable in Money Train 4

There are eight pay symbols: diamonds, clubs, hearts and spades as lows, plus four high‑pay characters. Scatter pays evaluate anywhere, so you’re aiming for eight or more of a high pay, or ten or more of a low. At the top end, 36 matching premiums can pay 100x to 1,000x, while 36 suits reach up to 125x. There’s no wild in this instalment, but the Respins and multipliers do the heavy lifting when clusters pile up.

Bonus squares trigger the Money Cart, acting as scatters, and persistent versions can help trigger too. The betting spread runs from 10p to £6 per spin in most builds I’ve played. During Respins, the chosen symbol sticks while multipliers float in and stack on a meter that multiplies the final hit. It’s a tidy twist that gives base play bite, and the paytable communicates thresholds clearly so you know when a screen is close to turning.

Bonus Features in Money Train 4

Respins may appear after any base spin. The most common symbol on the screen becomes sticky and the reels roll again, landing blanks, more of that symbol, or multiplier chips. Any new symbol of the chosen type sticks and the sequence continues; multipliers don’t stick, but their values add together and apply to the final win for that respin sequence. The feature ends when nothing new lands. It can throw out tidy screens when the meter climbs.

Land three or more bonus symbols to enter the Money Cart. You start on 6x4 with three spins that reset whenever a symbol lands, and persistent symbols act before the first roll. Fill a row to add a new one, up to 6x8, and any symbols on the newly opened row act at once. Modifiers include Collector, Persistent Collector, Adjacent Collector, Payer, Sniper, Collector Payer, Arms Dealer, Necromancer, Persistent Shapeshifter, Reset Plus, Upgrader, and the Unlocker, which opens a locked row.

Regions with feature buys get two choices. Pay 100x bet for standard entry into the Money Cart, or 500x to start with one guaranteed persistent symbol. When buying in, RTP rises to around 96.5% in the common configuration. I’ve had the most explosive setups when Upgrader turns regular features persistent, or when Sniper chains across big values. The variety is the draw here; combos can snowball fast, and the cap feels within reach on a hot script.

RTP, Volatility and Max Win in Money Train 4

Base RTP sits at 96.10%, though some operators run alternate settings, and buying the bonus can push it to roughly 96.50%. Volatility is rated 5/5, with a hit rate around 20.14%, so returns arrive in bursts rather than a steady drip. The ceiling is 150,000x stake, the highest in the series, and the scatter pays engine helps chunk value together during respins. It’s a fierce ride that rewards patience and a bankroll built for swings.

How to Play Money Train 4

Load the slot, let the intro roll, then tap the menu to read the paytable and feature pages. Set your stake with the plus and minus buttons; I tend to live between 20p and 60p for testing, then step up if the session runs well. Hit spin or use auto with sensible limits. In base, watch for respins selecting a dominant symbol. For bonus entry, you’re chasing three bonuses in view, or use the buy if available.

Money Train 4 – My Verdict

I’ve played every entry and this feels like the proper send‑off. The rebuilt respins make base play matter, while the Money Cart reaches peak variety with 20‑plus feature symbols and that new Upgrader doing real work. The off‑world setting looks ace and the flow between modes adds drama. It’s volatile, sometimes brutal, yet I never feel short of routes to momentum, especially when multipliers stack and a row opens to let modifiers chain.

It’s not a coffee‑break spinner. You need discipline, a clear plan for stakes, and the willingness to grind through dry stretches. In return, you get the most entertaining version of this engine, with a credible path to screen‑filling hits and that 150,000x cap. I’ll keep returning for the sequences where Sniper, Collector Payer and a freshly upgraded persistent symbol start playing off each other. When it catches, it’s blistering.
