Money Cart 4 closes the book on the bonus-only line the same way the 150,000x mainline finale closed the Money Train story proper: with the biggest cap in its family — 15,000x — and the late-series feature arsenal, including the Arms Dealer, Upgrader, Unlocker and Reset. Bets run €0.10 to €60, the widest range documented anywhere in the franchise. And there’s a strategic twist: this game was engineered for markets where bonus buys are restricted, the UK chief among them — it is the bonus, so there’s nothing to buy.
One thing this review won’t do is bluff. Relax has published only partial specifications: the RTP and exact release date are not stated in our sources (release falls somewhere around 2024–2025), and we flag both below rather than copy a number from thin air.
What We Know — and What We Don’t
| Spec | Detail |
|---|---|
| Provider | Relax Gaming |
| Release | Not published in our sources (~2024–2025) |
| RTP | Not published — no default figure in our sources; see the game id note below |
| Volatility | High (editorial rating; bonus-only format) |
| Grid | Bonus Reels format (full grid details not in our fact base) |
| Max win | 15,000x |
| Bet range | €0.10 – €60 |
That empty RTP cell is unusual for this site, and deliberate. Until the figure is confirmed, treat any RTP claim you see for Money Cart 4 elsewhere with suspicion — and remember that the famous 98% applies only to Money Cart 1 and 2, never to this game or the third Cart (96.00%).
Built for the Bonus-Buy Ban
Money Cart 4’s reason for existing is regulatory. In markets like the UK, buying a bonus round is prohibited — which neutralizes half the appeal of late-series Money Train games, whose buy menus (100x/500x in MT4) are core to how enthusiasts play them. Relax’s workaround is elegant: ship the bonus round as the game. Every spin of Money Cart 4 is a direct shot at triggering the feature, no purchase required, no base game in the way — the same structural trick the Money Cart line has always used, now aimed squarely at regulated audiences.
The UK-market game id, moneycart4_92, appears in Relax’s official materials. We’d note — as observation, not established fact — that suffixes like “_92” often denote a market build’s RTP configuration; if that convention holds here, the UK build would sit near 92%, well below the series’ defaults. Until Relax publishes actual figures, that stays a hypothesis, which is exactly why the verify flag above exists.
The Feature Set: MT4’s Arsenal, Cart Format
Where the first two Money Carts distilled the Money Train 1–2 era, MC4 distills the finale. The documented features:
- Arms Dealer — the late-series signature: it grants abilities to other symbols mid-round, effectively minting new specials on the fly and multiplying whatever the board is already doing.
- Upgrader — improves symbols into more valuable states, raising the board’s baseline rather than any single value.
- Unlocker — opens additional grid real estate, the Cart line’s traditional escalation (MC3 made unlockable reels its whole identity).
- Reset — refills the respin counter, the difference between a round dying at “almost” and a round reaching its second act.
Underneath them runs the standard engine: coin-value symbols, respins that reset with each new landing, and the payout tallied when the board goes quiet. The 15,000x cap — triple MC1’s and MC2’s combined ceilings, half again MC3’s — tells you the intent: this is the Cart line tuned for spectacle rather than the gentle math of its 98% ancestors.
The Cart Line, Completed
Line it up: Money Cart (2,000x, 98%), Money Cart 2 (5,000x, 98%), Money Cart 3 (10,000x, 96%), Money Cart 4 (15,000x, RTP unpublished). A perfectly linear escalation of ceilings and — where figures exist — a matching descent in return. That descent is worth understanding before you choose a stake; our RTP and volatility guide shows what each point of return means in session terms. MC4 is the natural endpoint of that curve and, per its official positioning, the final installment. Players choosing within the line should decide by priority: published-RTP maximalists go to MC2; ceiling chasers and buy-restricted players land here. The broader family context, mainline included, lives in our complete Money Train guide.
Where to Play Money Cart 4
Our primary pick is VAVADA, a full-catalogue Relax Gaming operator under an official distribution deal since March 2021 — the kind of carrier most likely to stock a late-series spin-off promptly. Incoming players get 100 free spins with no deposit plus a 100% welcome match up to $1,000, with a $1 minimum deposit, crypto and card support, and withdrawals that typically clear within 24 hours.

Crypto alternative: Housebets, a confirmed Relax carrier offering a 150% first-deposit match up to $1,000 — full notes in our Housebets review.
Demo note: demo availability isn’t documented in our sources for this title; where Relax free-play is offered, it’s the sensible first stop given the unpublished math.
FAQ
What is Money Cart 4’s RTP?
Not published in our sources, and we won’t invent one. The UK game id (moneycart4_92) hints at a possible 92% build for that market, but that reading is unconfirmed. Check the in-game info screen wherever you play — it is the only authoritative figure.
What is the max win?
15,000x your bet — the largest cap in the Money Cart line, though far below Money Train 4’s 150,000x.
Why was Money Cart 4 made?
Primarily for bonus-buy-restricted markets such as the UK: since the whole game is the bonus round, players in those markets get direct feature access without any purchase mechanic.
Is this really the last Money Cart?
That’s its official positioning — the final installment of the spin-off line, mirroring Money Train 4’s “final destination” branding on the mainline.
What’s the betting range?
€0.10 to €60 per spin — notably wider at the top end than Money Train 4’s €6 maximum.
Verdict
Money Cart 4 is a competent finale with an asterisk. The concept — MT4’s best features in a buy-free, bonus-only wrapper for regulated markets — is smart, the 15,000x ceiling is honest spectacle, and the €0.10–€60 range accommodates everyone. But we can’t fully grade a slot whose RTP isn’t published, and neither should you play it as if the old Money Cart math applies. Verify the figure in your lobby; if it comes back deep below series standards, MC2 remains the line’s true champion.
