Money Train 4 Slot Review

Money Train 4 Slot Review

As someone who has hammered every entry in this series since 2019, Money Train 4 feels like the right way to call time on the franchise. Relax Gaming has taken the dystopian, off‑world setting from the previous game and turned it into a full cinematic experience, with that gritty, Terminator‑style desert and a hulking, weaponised train dominating the screen.

Under the polish sits a vicious set‑up. Money Train 4 runs on a 6x6 grid with scatter pays, very high volatility, and a base RTP of 96.1% on the best setting. The hit rate sits around 20.14%, so you are looking at roughly one win every five spins. In return, the game waves a 150,000x max win in your face, which is about as serious as online slots get.

Base Game & Features in Money Train 4

The base game in Money Train 4 uses a scatter pays system rather than fixed paylines. You win when 8 or more high‑pay symbols or 10 or more low‑pay symbols land anywhere in view on the 6x6 grid. There are 36 positions, so you can land chunky clusters of the same symbol that stack into proper hits when the screen fills up.

Lows are the usual card suits – diamonds, clubs, hearts and spades. Highs are four characters most fans will recognise in one form or another: Payer, Sniper, Collector and Necromancer. At the top end, a full screen of Necromancer pays 1,000x, with other premiums stepping down through 500x, 400x and 250x for 36 of a kind. There is no wild symbol, but the feature set more than makes up for that.

Money Train 4 Respin Feature

The Respin feature in Money Train 4 can kick in at the end of any paid spin. The symbol that appears most often on the grid is chosen, all instances of it lock, and the rest of the positions respin. On those respins you only see blanks, that chosen symbol, or multiplier coins. New instances of the symbol stick and keep the feature running, while multipliers stack up and are applied to the final scatter win when the round finally dies.

Bonus Features & Free Spins in Money Train 4

Everything still revolves around the Money Cart Bonus in Money Train 4. You trigger it by landing 3 or more Bonus symbols anywhere, with gold persistent symbols able to stand in when they show up. The triggering symbols reveal bet multipliers, you start with 3 spins on a 6x4 board, and every new symbol that lands is sticky and resets the spin counter back to 3.

Fill a full horizontal row with symbols and an extra row above or below opens up, up to a maximum of 6x8. Any symbols already sitting on a freshly opened row spring into life straight away. The whole thing plays like a super‑charged hold‑and‑win: stacks of special symbols drop in, values climb, and you grind towards that cap while the spin counter ticks between 1 and 3.

Most of the famous roles return here. You get collectors that pull in values from around the board, payers that spray fresh value onto other symbols, snipers that double targets, and persistent versions of all of them that act every spin instead of once. When you add in new toys like the Upgrader, Reset Plus and more adjacency effects, the bonus becomes an intricate engine where a single good drop can change the whole picture.

Money Train 4 Money Cart Bonus Modifiers

The list of modifiers in the Money Train 4 Money Cart round is long, but a few stand out in practice. Standard Bonus symbols just carry 1x to 10x, while Collector and Persistent Collector pull every visible value into their own count, with the persistent version doing it on every spin. Payer, Adjacent Payer and their persistent cousins work the other way round, adding fresh value onto everything in sight or just neighbouring symbols.

Snipers double three to eight targets, sometimes hitting the same symbol more than once. Collector Payer combines both jobs at once. Arms Dealer converts basic Bonus icons into feature symbols, which then act straight away, and Necromancer revives used special symbols so they act again. The Upgrader is the new star: hit one early and it can turn one to three regular feature symbols into persistent versions, which is how you get those completely unhinged boards where numbers snowball out of control.

Bonus Buy in Money Train 4

If you can use buys in your region, Money Train 4 gives you two choices. For 100x your stake you buy straight into a standard Money Cart Bonus. For 500x, you begin the feature with one persistent symbol guaranteed on the grid from the start. Both options run on an improved RTP of 96.5%. Personally, I prefer to grind normal buys and let the occasional natural persistent set‑up carry the session.

Money Train 4 Verdict

From a seasoned player’s point of view, Money Train 4 does what it had to do. The visuals and soundtrack hit that big‑budget sweet spot, the scatter pays base game finally feels like it can produce proper hits without the bonus, and the Money Cart round has more depth than almost any hold‑style feature on the market. When the right combination of collectors, payers, snipers and an Upgrader line up, the screen just goes mad.

The flipside is obvious. This is a very high‑variance slot with a 150,000x ceiling for a reason, and dry patches can be long, even with the decent hit rate and respins helping. I would not send low‑risk players here. If you are comfortable with sharp swings, enjoy working out how different modifiers interact, and liked the earlier games for their potential rather than their comfort, Money Train 4 is a fitting last ride for the series.
