Money Train 4

Overview

Money Train 4 is Relax Gaming’s September 2023 conclusion to the Money Train series — a 6×4 grid with 40 ways to win, 96.10% RTP, very high volatility, and a 150,000× max win that places it among the heaviest-ceiling slots in the entire 2023 catalogue. Released as the final chapter of one of the most-played progressive slot series of the late 2010s and early 2020s, Money Train 4 keeps the franchise’s signature money-symbol collection mechanic while bumping the visual theme into a Wild West heist setting. The 20.14% hit frequency is the lowest in the entire batch, consistent with the slot’s very-high-volatility tuning. The €0.10–€5 betting range fits the bankroll math against the headline ceiling sensibly.

Key Stats

How It Plays

A 6×4 grid with a deliberately narrow 40-way pay structure — consistent with the rest of the Money Train series and Relax Gaming’s house style of trading ways-count breadth for variance-mechanic depth. Matching symbols on consecutive reels starting from the leftmost reel pay along the 40 defined paying patterns. The 20.14% hit frequency is genuinely low — expect roughly one paying spin in every five during base play — consistent with very-high-volatility tuning.

The defining gameplay carries forward the Money Train series’ signature framework: scatter symbols trigger a feature-rich bonus round where money symbols accumulate values and persistent special symbols compound their effects across spins. The base game is engineered to fund waiting for the bonus trigger; the bonus round is where the entire 150,000× variance ceiling lives. Visually, Money Train 4 trades the steampunk-and-zombie themes of the earlier series entries for a dusty Wild West heist setting — outlaws, locomotives, and golden-hour desert landscapes — which gives the franchise’s concluding chapter a meaningfully different visual identity from its predecessors.

Bonus Features & Special Symbols

Money Symbols & Persistent Specials

The Money Train series’ defining mechanic. Money symbols carry random cash values printed on each symbol in stake-multiplier terms. During the bonus round, special symbols (Collector, Payer, Necromancer, Sniper-style mechanics carry across the series) interact with money symbols to compound their values across spins. The bonus round is the entire variance story — base-game wins are designed to fund waiting for the trigger.

Feature Buy

Relax Gaming ships a feature buy option that allows direct entry to the bonus round at a fixed stake multiplier. The cost is typically substantial (often 100×+ stake) reflecting the heavy ceiling. Feature buy availability varies by market — UK and Netherlands typically restrict the feature. The feature buy is particularly meaningful on Money Train 4 given the 20.14% base-game hit frequency: grinding 500-spin sessions for an organic trigger is significantly more bankroll-intensive than purchasing direct entry.

Wild Symbols & Persistent Mechanics

Wild symbols substitute for any standard symbol to complete winning combinations. Persistent special symbols stay on the grid for the duration of the bonus round once landed, accumulating effects across spins — producing the compound variance that puts 150,000× within mathematical reach.

RTP, Volatility & Math Notes

96.10% RTP sits roughly on the broader industry average and is appropriate for a slot with a 150,000× ceiling — the math is engineered around the bonus round producing exceptional variance peaks rather than spreading RTP evenly. Very high volatility paired with a 20.14% hit frequency produces a session profile that’s genuinely punishing for shallow bankrolls — the bulk of the math’s output is concentrated in rare but heavy bonus-round triggers with persistent-symbol compounding.

Practical session profile: a €100 budget at €0.20 stakes (500 spins) is the realistic floor for a fair test. With 20.14% hit frequency, expect about 101 paying spins out of 500 — mostly modest base-game returns, with sessions effectively defined by whether the bonus round triggers and how heavily the persistent-symbol mechanics interact during the round.

Practical bankroll guidance per stake tier: €0.10 stakes — minimum €50 for a 500-spin fair test, ideally €100; €0.50 stakes — minimum €250; €2 stakes — minimum €1,000; €5 stakes — minimum €2,500 for sustained sessions, €5,000+ for serious chase play. The 150,000× ceiling means even at €5/spin the headline win is €750,000, which exceeds most operators’ per-spin payout caps — verify operator-specific limits. Relax Gaming ships RTP variants below 96.10% across markets — verify the in-game info panel before depositing.

Paytable & Top Symbols

The paytable runs on Wild-West-themed outlaw symbols rather than card royals on the top end — cowboy characters, sheriff badges, locomotives, and themed Western imagery fill the high-paying tier. Card royals (A, K, Q, J, 10) sit at the bottom with dusty-frontier reskins and fill the bulk of base-game paying combinations on the rare spins that pay. Money symbols and persistent special symbols operate outside the standard paytable as feature symbols. Always check the in-game paytable for exact 3-, 4-, and 5-of-a-kind multipliers, since these can shift between RTP variants.

Betting, Bankroll & Demo Tips

€0.10–€5 betting range is the standard Relax Gaming ceiling for extreme- and very-high-volatility releases. The €0.10 minimum keeps the slot accessible to micro-stakes players exploring the variance class; the €5 cap keeps the bankroll math sensible against the 150,000× ceiling. At maximum stake the 150,000× ceiling produces a per-spin headline win of €750,000, which exceeds most operators’ per-spin payout caps — the practical maximum is whatever the operator’s cap allows.

In demo mode, focus specifically on bonus-round triggers and how the persistent special symbols accumulate effects during the round. The 150,000× ceiling is genuinely a long-tail event — spending 5–10 demo feature-buy entries gives a far better read on the round’s math than 1,000 base spins, particularly given how rare organic triggers are at a 20.14% hit frequency. Understanding what the typical bonus round looks like (versus the rare exceptional sessions where the headline figure becomes attainable) is the most useful preparation.
