Money Cart 4 Slot Review
Relax Gaming returns with Money Cart 4, their latest instalment in the Money Cart series. Designed specifically for regulated markets where bonus buys are restricted, this game strips away the lengthy base game of its Money Train cousins and pivots entirely to a bonus-focused experience. The result is a tightly crafted respin mechanic featuring high volatility gameplay, a 15,000x maximum win potential, and a sophisticated 17-symbol system that rewards player expertise. Released in June 2024, Money Cart 4 targets experienced players in bonus-buy-restricted territories seeking premium mechanical depth.
Base Game & Features
Money Cart 4 operates on a distinctly unusual premise for modern slots. The game uses a 6-reel grid with dynamic rows that expand from a base 4-row layout up to 8 rows during bonus play. Rather than traditional paylines, the game employs a dynamic all-ways-pays system, meaning winning combinations can form across any configuration as the rows expand.
The critical design choice lies in the game’s symbol setup. Bonus symbols are the only symbols that appear on the base reels—there are no traditional paying symbols during standard spins. This creates a distinctly bonus-focused gameplay loop where the primary objective shifts from chasing base game wins to triggering the re-spins feature. Landing 3 or more bonus symbols activates the bonus round, with an approximate frequency of roughly 1 in 10 spins.
The betting range of 0.10 to 60 per spin offers accessibility for both cautious and aggressive players. Importantly, the game uses a coin value system where each symbol displays its value in coins rather than direct bet multipliers—a 500 coin win equals 50x your stake, not a direct multiplier. This system is integral to understanding realistic win expectations and how the 15,000x maximum win is calculated. The RTP sits at a standard 96.00%, positioning the game competitively within the modern online slot landscape.

Bonus Features & Free Spins
Money Cart 4’s primary feature is its re-spins bonus mechanism, which replaces traditional free spins entirely. When you land 3 or more bonus symbols, the game awards 3 initial respins. The critical mechanic: whenever any symbols land during your respins, your respin counter resets back to 3, theoretically allowing the bonus to continue indefinitely if symbols continue to land.
During the bonus round, the grid expands dynamically from its base 4 rows up to 8 rows, creating additional winning opportunities as the space increases. This mechanical expansion works in tandem with a sophisticated symbol system featuring 17+ special symbols, each with distinct functions designed to build and multiply wins.
Key Bonus Symbols:
- Persistent Shapeshifter: Evolves after each spin into one of five different feature types—Collector, Payer, Sniper, Arms Dealer, or Unlocker—adding unpredictability and depth to each bonus round.
- Upgrader: Converts 1 to 3 feature symbols into their persistent versions, allowing regular symbols to carry their effects through the entire bonus round.
- Collector: Gathers all visible symbol values and adds them to its own total, creating compound win potential as the bonus progresses.
- Payer: Reveals a random value and applies it to all symbols on the reels, significantly boosting overall win calculations.
- Sniper: Doubles up to 8 symbols per spin, creating dramatic win acceleration when positioned optimally.
- Arms Dealer: Transforms up to 4 symbols into feature symbols, expanding the number of high-value elements in play.
- Necromancer: Revives 2 to 7 previously used non-persistent symbols, maintaining bonus momentum and extending the feature.
This symbol variety creates mechanical sophistication comparable to Money Train 4 despite the condensed format. The game includes no traditional free spins or bonus buy feature—a deliberate design choice for regulated markets where such features are restricted. Players must land the required bonus symbols naturally during gameplay to access the respin feature.

Our Honest Verdict
- Overall Verdict: 7.8/10
- Money Cart 4 succeeds as a premium alternative to Money Train 4 for regulated markets, delivering mechanical sophistication through its respin mechanic and complex symbol system. The 96% RTP is standard for modern slots, but the frequent bonus triggers (approximately 1 in 10 spins) and 17-symbol mechanics provide substantial engagement. Relax Gaming has maintained the excitement and mechanical depth of the original franchise despite condensing gameplay into a bonus-focused format. The 15,000x maximum win potential, paired with high volatility (5/5 scale), creates appealing upside for experienced players. However, the absence of meaningful base game content restricts this game to a specific audience. The coin system also means higher per-spin costs relative to traditional slots, which may impact budget-conscious players. Money Cart 4 excels as a solution for experienced, volatility-seeking players in bonus-buy-restricted markets, but it explicitly excludes casual players and those who value base game variety.
Best for: Experienced players in bonus-buy-restricted markets seeking high-volatility, bonus-focused gameplay with mechanical complexity.
Not recommended for: Casual players, base-game preference players, and budget-conscious slots enthusiasts.
