GreatSlots review · Relax Gaming · 2020
Money Train 2 is one of the slots that changed expectations for feature-heavy bonus rounds. The base game is not the reason people remember it; the Money Cart Bonus is, because collectors, payers, snipers, and necromancer-style modifiers can keep a round alive in unusual ways.

Best for
players who want a complex bonus round with huge upside
A top-tier very-high-volatility pick for players who want deep bonus mechanics and a massive ceiling.
Money Train 2 became a modern benchmark because its 50,000x ceiling is tied to a bonus round where persistent characters can keep compounding value.
Money Train 2 uses a 5x4, 40-line base game, but the main review focus is the Money Cart Bonus. Three or more scatters start the round, and the feature then plays out through special character symbols with different jobs.
The important distinction is persistence. Some symbols stay and keep acting across spins, while others resolve once. That is what makes strong rounds feel like they are building a machine rather than just revealing random values.
Money Train 2 suits players who actively want very high volatility and are willing to learn a deeper feature system. It is one of the better examples of a complex bonus round that still has understandable logic.
It is less suitable for players who want simple paytables, frequent base-game value, or a relaxed session. The game is built around waiting for a bonus that can either fizzle or explode.
The mobile version is playable, but the bonus round is information-heavy. The symbols are clear enough, yet it helps to understand the main character roles before judging a feature.

Extra Chilli is a sharper Megaways follow-up to Bonanza, built around rolling reactions, a volatile free-spin gamble, and a bigger ceiling than the mining classic.

Bonanza still matters because it made Megaways feel simple: variable reels, dual-direction cascades, and free spins with an unlimited win multiplier.
Its Money Cart Bonus combines persistent character symbols with a 50,000x max-win ceiling, which gives the feature rare escalation potential.
The base game is simple, but the bonus round takes time because each special symbol has a different role.
Yes. It is built around long waits for bonus rounds that can vary sharply in value.
