Money Train: Relax Gaming’s heist saga, explained for casino operators
How the Money Cart respin bonus works, how the four episodes differ, who plays them, and what your wallet should expect when you list the saga.
In short. Money Train is a Relax Gaming slot series started in 2019 and built around the Money Cart respin bonus, where cash symbols and characters like the Collector, Payer and Sniper interact; Relax publishes a 50,000x max win for Money Train 2. Operators add every episode through the SoftAggregator API.
What is Money Train?
Money Train is a series of Wild West heist slots by Relax Gaming. The first game came out in 2019; Money Train 2 followed in 2020 and turned the series into a reference for high-volatility players; Money Train 3 and Money Train 4 raised the stakes again. Each episode is built around the same heart: the Money Cart bonus, a respin feature where cash symbols and special characters stick to the reels and interact with each other.
For operators, Money Train is a signal game for the high-volatility audience, like the Hacksaw and Nolimit City hits. Its players compare casinos by whether the whole saga is available, not just one episode.
The Money Cart bonus, explained simply
Every Money Train game shares the same bonus logic, with new characters in each episode:
- The bonus opens with a few respins, usually three. Any new bonus symbol that lands sticks and resets the respin count.
- Bonus symbols carry cash values. Special symbols act on them: a Collector adds up the values on screen, a Payer adds its value to every other symbol, a Sniper multiplies random symbols, a Necromancer brings used symbols back.
- Later episodes add persistent versions of these characters, which act on every respin, and extra reels that unlock during the feature.
- When the respins run out, or the whole screen is full, everything visible is paid.
The interaction between characters is the whole appeal: a Payer landing next to a persistent Sniper can multiply the entire screen. It is a slow build and a sudden climax, and it is excellent to watch.
The saga at a glance
| Episode | Year | What operators should know |
|---|---|---|
| Money Train | 2019 | The original; the Money Cart concept in its simplest form |
| Money Train 2 | 2020 | The breakout episode, with a published maximum win of 50,000x the stake; RTP published in the game rules |
| Money Train 3 | 2022 | More persistent characters and a higher ceiling |
| Money Train 4 | Latest | The latest episode, pushing the ceiling further |
Relax publishes the RTP of each episode in its game rules, and like several studios it offers more than one RTP configuration, so the value in your lobby depends on the build you receive. All episodes are firmly high to very high volatility.
Players and markets
Money Train players are experienced and often play at higher stakes. They follow the saga’s releases, watch big wins on streaming platforms and move to a new episode on release day. The series is strong in the Nordics, Central Europe, Canada, the United Kingdom, Latin America and on crypto-oriented casinos. It rarely leads in markets dominated by small-stake mobile play; there it works as a premium title for the VIP segment.
Similar games for the same player
- Wanted Dead or a Wild and Le Bandit (Hacksaw Gaming).
- Mental, Tombstone RIP and San Quentin (Nolimit City).
- Dead or Alive 2 (NetEnt) — the other Wild West legend of high volatility.
- Hold-and-win titles with collector symbols from Pragmatic Play, Playson and Wazdan, for players who love the respin format at lower volatility.
How to list the Money Train saga with SoftAggregator
Relax Gaming titles come through the same casino games aggregator connection as everything else. There is no special build: match “Money Train” in the slots entries of getGameList, keep each episode’s id_hash, and launch with getGame.
Two points deserve a check in your wallet code. First, the Money Cart bonus can be bought in the versions that offer a bonus buy: that is one large debit. Second, a big respin payout is a single large credit — and if the bonus was triggered naturally, that credit has no debit of its own. The wallet callback rules cover both: de-duplicate on call_id, never cap credits, and make sure very large minor-unit amounts fit your data types.
The currency is fixed at launch. EUR, USD, CAD, SEK, NOK, GBP, PLN, CZK, BRL, MXN, TRY and a wide range of others are native; for a currency outside the list the account uses USD or EUR and you convert on your side. Titles arrive in the catalogue continuously, and the API is always the up-to-date list; if the saga matters to your launch, we confirm each episode for your currency.
