Money Train 4 – Slot Overview

Money Train 4 is the final and most ambitious chapter in Relax Gaming’s legendary Money Train series. Since the original release in 2019, the franchise has built a reputation for extreme volatility, complex bonus mechanics, and massive win potential. The fourth installment takes everything to the limit, delivering the biggest grid, the most feature symbols, and the highest maximum win in the series.

Set in a futuristic off-world dystopia, Money Train 4 combines cinematic visuals with intense gameplay. The base game feels clean and minimal, while the bonus round shifts the atmosphere into a darker, rain-soaked environment. This contrast reinforces the high-risk, high-reward nature of the slot.

Base Game Mechanics

The base game runs on a 6×6 grid using a scatter pays system. Wins are formed by landing:

  • 8+ identical high symbols, or

  • 10+ identical low symbols
    anywhere on the reels.

There is no Wild symbol, but this is compensated by multiple special mechanics and a Respins feature that can create meaningful base-game payouts.

Symbols Overview

Symbol Type Details
Low Symbols Card suits: Diamonds, Clubs, Hearts, Spades
High Symbols 4 character symbols
Minimum Win 0.4x bet
Maximum Base Win Up to 1,000x bet (36 symbols)

Respins Feature

The Respins Feature can trigger after any base game spin.

How it works:

  • The most common symbol becomes sticky.

  • Respins continue while new symbols or multipliers land.

  • Multipliers stack and apply to the final win.

  • Pay symbols remain locked; multipliers do not.

  • The feature ends when no new symbols appear.

This mechanic reduces long dead-spin sequences and adds value outside the bonus round.
