Money Train 4

Money Train 4 is the most technically ambitious entry in Relax Gaming's flagship series: a 6x6 grid that plays scatter pays, requires no payline alignment, and contains over 20 distinct special symbols in the Money Cart bonus. Released in September 2024, it pushes the max win to 150,000x, the highest in the Money Train franchise, while adding Persistent modifier variants and a new Upgrader mechanic. Available on desktop and mobile with crypto at Wild.io.

What is Money Train 4?

Money Train 4 is a 6x6 video slot from Relax Gaming with 94.0% RTP, very high volatility, and a top win of 150,000x your bet. The game uses scatter pays, meaning wins form when 8 or more matching symbols appear anywhere on the grid, not on fixed paylines.

The Money Cart bonus is the centrepiece, triggered by landing the Bonus Symbol on the scatter-pay grid. Inside the feature, over 20 special symbol types interact, including Collectors, Persistent Collectors, Adjacent Collectors, Payers, Snipers, a new Upgrader symbol, and the returning Necromancer that reactivates spent modifiers. A bonus buy option lets players enter the feature directly, and the very high volatility means the game is built around infrequent, high-magnitude hits.

Money Train 4 Slot Theme & Graphics

Money Train 4 keeps the futuristic-train aesthetic introduced in Money Train 3 but renders it with significantly more visual detail. The 6x6 grid gives the reels a cinematic presence, and character symbols, Indian Chief, Arms Dealer, Cowboy, and Cowgirl, are rendered in sharper detail than earlier entries. The bonus round environment shifts to a darker, more industrial tone, with the expanding grid filling the frame during extended feature runs.

Audio design tracks the feature's tension closely, with modifier activations triggering distinct sound cues that help players track what's happening across a complex grid. Mobile performance handles the 6x6 layout well, and the bonus buy entry point makes the most active part of the game immediately accessible. The combination of wild-west characters with a mechanical train heist aesthetic is fully realised by the fourth installment.

Money Train 4 Slot Symbols & Paytables

Money Train 4 has two distinct symbol pools: the scatter-pay base game symbols and the Money Cart bonus modifier system with over 20 special types.

Special Symbols

Money Train 4 has no Wild symbol. Inside the Money Cart bonus, over 20 modifier types activate: Bonus Symbols carry coin values. Collector gathers all visible values and adds them to itself; Persistent Collector repeats that action every spin. Adjacent Collector absorbs the 8 surrounding positions once; Persistent Adjacent Collector does the same on every spin. Payer adds its value to all visible symbols once; Persistent Payer repeats every spin. Sniper doubles 3 to 8 money symbols multiple times. Necromancer reactivates previously used modifiers. The Upgrader converts standard modifier symbols into their Persistent variants mid-feature, significantly extending their effect window.

Money Train 4 Bonus Feature & Special Features

Money Cart Bonus

The Money Cart bonus is the sole source of high-value wins. Landing the Bonus Symbol on the scatter-pay grid triggers 3 respins; the counter resets whenever a new symbol lands. Coin symbols carry values, and over 20 modifier types activate automatically on the positions they land. A single Persistent Collector landing early can collect values from every subsequent coin symbol for the remainder of the feature. The Upgrader symbol, new to Money Train 4, transforms standard Collectors, Payers, and Snipers into Persistent variants, massively extending their contribution. In a maximum-length feature with multiple Persistent modifiers stacking, the 150,000x ceiling becomes reachable, but requires a combination of high modifier density, an upgraded modifier set, and sustained respin resets.

Bonus Buy

The bonus buy lets players skip the base game and enter the Money Cart bonus directly at a fixed multiple of their stake. This option makes the full modifier system immediately accessible without grinding through the scatter-pay base game. For high-volatility players targeting the 150,000x max win, bonus buy is the most efficient way to allocate session budget toward the feature. Responsible gambling: bonus buy carries the same high-volatility risk profile as the standard game, set a clear budget before using it.
