What we know

Money Train 4 closed the series Relax Gaming built its name on, and until Money Train 5 was announced in June 2026 it was meant to stay closed. Relax gave it a 150,000x ceiling, the largest in the studio's catalogue at the time, and stacked more than twenty features onto the Money Cart bonus round. The additions were an Arms Dealer that trades bonus symbols for feature symbols, an Unlocker that reveals extra rows, an Upgrader that makes feature symbols persistent, and a Reset that refills the spin counter. A respin feature extends the base game as well. The data is thin, and that is Relax's doing rather than ours: their game page lists game type, payout mechanic and a bet range of 0.10 to 6 euro, and stops there. No return figure, no hit frequency, no reel layout, no max win probability. Volatility exists only as the word high-volatility in the launch announcement. One thing the page does document is a second build - it names an alternative UK game ID, moneytrain4_92, which confirms a reduced version exists without stating what it returns. Rather than infer a percentage from an identifier, we have left our RTP field blank.
