Money Train 4: high volatility, 150,000x max win

Money Train 4 is a high-volatility Relax Gaming title with a 150,000x max win. Operators can legally ship a reduced-RTP configuration of the same title without disclosing it in the lobby, so the paytable in the game's info screen is the figure to trust.

Questions readers ask

We haven't field-tested a per-operator build for this title yet. Until we have, treat the published return as the ceiling, not a guarantee at any specific casino.

Money Train 4: our verdict

The last stop on Relax Gaming's Money Train line: a scatter-pays slot the studio says carries more than 20 features, a 150,000× ceiling and a bet capped at €6.

Why it is on the list

Money Train 4 is the final entry in Relax Gaming's series, and the studio's own page frames it that way: the bandits ride the rails "for the last time". It is listed as a video slot with a scatter-pays payout mechanic, and Relax counts more than 20 features in it. The headline figure is the ceiling. At 150,000× the bet it sits level with San Quentin xWays as the highest max win on this list, which is the reason it is here.

How it plays

Relax's page names the new pieces rather than explaining every rule. The Arms Dealer joins the cast and hands out features in exchange for Bonus symbols at any moment. A Respin feature extends the base game, an Upgrader gives features a persistent edge, an Unlocker reveals more rows, and a Reset feature refills the spin counter. Beyond that, the studio's page does not spell out the rounds in detail; its own demo, behind the Try Game button, shows the rest.

The maths

Relax does not print a return on this game's page, so the 96.1% we carry for Money Train 4 cannot be confirmed there; the paytable inside the game is where to check the build you are on. Volatility is high. Max win is 150,000× the bet, a figure the studio states itself. The bet range on the page is €0.10 to €6, low for a game with this ceiling, so the top end is reached through the multiple, not the stake.

Who it is for

Players who want the largest multiple on offer and are content with a small maximum stake to chase it. If you want the same 150,000× ceiling from a studio that publishes its return on the game page, San Quentin xWays lists 96.03%. If 150,000× is more variance than you want, Le Bandit stops at 10,000×, a fifteenth of the ceiling.
