Money Train is the original Relax Gaming western slot from 2019 that launched what would become one of the most successful bonus round templates in modern slots. The Money Train Hold and Win feature — with its interacting Banker, Collector, and Payer special symbols — introduced a persistent win round mechanic that has since been widely imitated, spawning sequels and inspiring numerous other developers. The original remains essential playing.

The game plays across 25 paylines with bets from $0.10 to $100 per spin. The western train robbery aesthetic features bandits, steam locomotives, desert landscapes, and frontier imagery in a warm, atmospheric presentation. The visual design established the template for the entire Money Train series.

The Money Train Hold and Win feature is the mechanic that defined the game’s legacy. Three special symbol types interact during the respin sequence: the Banker accumulates total values, the Collector multiplies values of adjacent symbols, and the Payer distributes values to other positions. The interaction between these three symbols creates a persistent win round where each new respin has the potential to generate additional symbol placements and compounding interactions. It’s a feature with real strategic depth that rewards understanding of how the symbol types affect each other. A Bonus Buy option provides direct entry.

RTP is 96% with very high volatility and a max win of 5,000x your stake. The very high volatility reflects the feast-or-famine nature of a feature entirely dependent on how the special symbol interactions play out.

Money Train is required playing for any serious slot player. It established the template that many current slots are built from, and it still plays superbly. Very high variance — but that’s the point.
