Money Train 4 by Relax Gaming Slot Overview
Money Train 4 by Relax Gaming continues the series behind Money Train 3, combining a sci-fi western setting with desert canyons and glowing machinery. Here, a 6-column, 6-row Scatter Pays grid and an expanding bonus board give the rugged train-heist atmosphere a distinctive mechanical identity.
A 150,000x maximum win sits in the Money Cart Bonus Round, where the Persistent Collector gathers other visible values after every spin. Unlockable rows and interacting feature symbols add depth beyond standard respins, and BonusTiime rates the volatility High.

Money Train 4 Slot Features

Money Cart Bonus Round, Respin Feature, Persistent Feature, and Original Feature drive Money Train 4, while layered symbols such as Collector, Payer, and Sniper create a bonus system that keeps changing the value of every round.
Respin Feature
The Respin Feature can trigger at the end of any spin, except when the bonus game is triggered. The symbol most present on the reels becomes sticky, then a re-spin begins. Only that symbol, multiplier symbols, and blanks can land, and multipliers add together before the final win is calculated.
Money Cart Bonus Round
Landing 3 or more Bonus symbols anywhere on the reels starts the Money Cart Bonus Round. Persistent gold symbols can also trigger it. The bonus begins with 3 spins and 6 columns by 4 rows, then can expand by 4 additional rows. New symbols reset the spin count to 3.

Money Train 4 Slot Review
Money Train 4 leans into a sci-fi western look with desert rock, industrial framing and a heavy train heist identity. The visual mix is more than decoration because the whole game is built around a mechanical bonus board and a 6 by 6 Scatter Pays layout. That gives it a distinct house style.
The real strength sits in the Money Cart Bonus Round, where symbols stack, reset spins and interact through collectors, payers and snipers. That makes each bonus round feel busy in a controlled way, although the base game itself stays in the background. The 150,000x ceiling and a volatility BonusTiime rates High explain why the game holds back before it opens up.
Money Train 4 centres its design on a bonus round with 3 starting spins and two direct entry options. The Persistent Feature starts the round with 1 Persistent symbol for x500 the bet, while the Original Feature costs x100 the bet. That structure gives the slot depth, but it also makes the experience feel bonus dependent.
