Money Train is a series of six hold-and-win video slots from Relax Gaming, built around the Money Cart bonus round: hold a grid of positions, respin, and let special symbols pay you, multiply you or collect for you. The original launched in the summer of 2019; four sequels and a jackpot-linked remake followed, each keeping that respin-and-collect core while changing the grid, the specials and the maths model. The newest instalment, Money Train 5, is scheduled for 24 September 2026. This page compares all six games side by side, with a link to the full review and free demo of each.
The six games at a glance
| Game | Released | RTP | Max win | What makes it different | Demo |
|---|---|---|---|---|---|
| Money Train | Summer 2019 | 96.20% (98.00% buy) | 20,000x | Stacked symbols and the simplest bonus round started the whole formula | Money Train demo |

| Money Train 4 | 20 September 2023 | 96.10% (96.50% buy) | 150,000x | 6×6 scatter-pays grid, no wild — the series’ highest max win | Money Train 4 demo |
| Money Train Origins Dream Drop | June 2023 | 94.00% DD / 96.11% | 10,000x + jackpots | Original wild-west setting wired into Relax’s Dream Drop jackpots | Money Train Origins demo |
| Money Train 5 | 24 September 2026 | 96.10% | 50,000x (100,000x Ultra) | Post-apocalyptic theme, Nuclear Wild and a station-based free spins round | Money Train 5 demo |
A quick note before the details: bonus buys spend your stake many times faster than a normal spin, and every max win figure above is a ceiling, not a typical result. Treat both as maximums, not expectations.
The six games, one at a time
Money Train (2019)
Money Train is where the hold-and-win Money Cart bonus started. Released in the summer of 2019, its 5×4, 40-line grid stays simple: stacked symbols, one Wild, and the shortest specials list in the series — Payer, Collector and Widener, with persistent versions of the first two. RTP is 96.20% (98.00% with the 80x bonus buy), and the max win is capped at 20,000x. It’s still live alongside its 2023 remake, Money Train Origins Dream Drop, and remains the clearest way to see how the series’ bonus round works.

Money Train 2
Money Train 2 is the most searched game in the series, helped by its steampunk wild-west setting. The base game’s Respin feature climbs by 1x on every non-winning spin, and the Money Cart bonus can grow from 5×4 to 7×4, adding 500x for a full grid. Specials include Sniper, Necromancer, Reset Plus and a Golden Bonus worth 20–200x. RTP is 96.40% (98.00% with the 100x bonus buy), and the max win is 50,000x.

Money Train 3
Money Train 3 trades the wild west for a darker, futuristic look, and picked up several Slot of the Year awards in 2022. Its base game can trigger a random sticky respin with an x1, x2 or x3 multiplier, and the bonus adds Absorber, Tommy Gun Sniper, Tommy Gun Payer and a Persistent Shapeshifter that changes identity each spin. RTP is 96.10% (96.50% bought), the bonus lands roughly once every 435 spins, and the max win reaches 100,000x across four bonus-buy tiers from 20x to 500x.

Money Train 4
Money Train 4 breaks from the format outright: a 6×6 scatter-pays grid with no paylines and no wild, where eight or more matching high-value symbols (ten or more low-value) pay out anywhere on the reels. It carries the series’ highest max win, 150,000x, backed by 23 special symbols including Arms Dealer, Unlocker and Upgrader. RTP is 96.10% by default, though 94.00% and 90.00% versions exist at some casinos — worth checking the in-game info screen. Billed at release as the finale, it was the last game before Money Train 5 was announced.

Money Train Origins Dream Drop
Money Train Origins Dream Drop returns to the original 2019 wild-west setting and wires it into Relax Gaming’s Dream Drop progressive jackpot network, with five seeded tiers from Rapid up to Mega. Two RTP versions exist: 94.00% feeds the jackpot pool, while a 96.11% non-jackpot version skips it and allows an 80x bonus buy instead. The bonus adds two new specials, Banker and Healer, alongside Collector and Payer. Outside the jackpots, the max win is 10,000x — modelled at roughly once in 7 million spins.

Money Train 5
Money Train 5 releases on 24 September 2026; this overview is written from the pre-release demo build we tested. The post-apocalyptic entry adds a Nuclear Wild base feature and a free spins round where a train moves through numbered stations, unlocking new mechanics at stations 5, 10, 15 and 20. Standard Mode caps the win at 50,000x; Ultra Mode doubles that to 100,000x but limits the bet to 10. RTP is 96.10% in the build we saw, and details may change at launch.

New: Money Train 5 (out 24 September 2026)
Money Train 5 is the reason parts of this page carry a pre-release note. Relax Gaming has set the launch for 24 September 2026, and the figures above come from the demo build available ahead of that date, including a Super Charge buy menu running from 10x up to 2,000x. Once the game is live, the review and demo page will be updated with any details that change at launch.

Guides
Five deeper guides cover the series as a whole:
- Money Train RTP & volatility — RTP, bonus-buy RTP and hit frequency for all six games.
- Money Train bonus buy — every buy-feature price, and what each one actually gets you.
- Money Train max wins — how each ceiling is reached, and how rare it really is.
- Money Cart symbols glossary — an A–Z of every special symbol in the series.
- Money Train series compared — which game suits which kind of player.
How we test
Every page here starts with the demo, not a press release. I spend time in each game’s free-play mode, read the paytable and rules screens, and note what the maths model actually shows rather than what marketing copy claims. Figures such as RTP and max win are checked against more than one independent source, and where sources disagree, the page says so. Reviews get revisited when a casino runs an alternative RTP version, or when a game itself changes — as Money Train 5 will on 24 September 2026.
