How the round runs
You start with a few respins. Each new coin locks and resets the count. The round ends when respins run out or the grid fills.
Symbol roles
Collectors add up values, payers add to others, multipliers raise them, and persistent versions act again each respin. The big results come when several persistent symbols land early.

Our verdict
Money Train 4 is built for one thing: its respin bonus round. The base game is a way to reach that round, and it can take a long time to do so. Inside the round, coins lock onto a grid, each new landing resets the respin count, and special symbols collect, pay, multiply or keep acting on every respin. When the right roles land early, the board can snowball into a large total. When they don't, the round can end with a thin board and a payout below the cost of getting there. That's high to extreme volatility in practice. If you enjoy watching a board fill and can afford a session that ends with nothing, it's one of the most involving bonus rounds around. If you want regular wins, look elsewhere. The RTP for the base game and the buy, the buy price and the max win are in the info panel.
A round, start to finish
- The round starts with a few coins already on the grid and a set number of respins, shown on screen.
- Each respin, empty positions can land new coins or special symbols.
- Anything that lands locks in place and resets the respin count.
- Special symbols act when they land, or on every respin if they're persistent.
- The round ends when respins run out or the grid fills. All values on the grid are added and paid.
Why the order matters
A collector or payer that lands early has more respins to work with, and a persistent one keeps acting for the rest of the round. A symbol that multiplies values does more when the board is already full. So the same symbols can produce wildly different totals depending on when they arrive. That's the main reason two rounds of the same game can look nothing alike.
Buying the bonus
Where local rules allow it, the buy menu lets you start the round for a fixed multiple of your bet. Some versions offer more than one buy level. Read the price and the RTP for the buy in the game. Each buy is one large bet, and a run of thin boards can use up a budget quickly. Decide the number of buys before you start.
How it compares
Our Relax Gaming page explains the series and how its sequels differ. Big Bass Bonanza is a gentler take on collecting values. Tombstone RIP is another extreme game, built on sticky wilds rather than a board. Razor Shark shows a different high-volatility approach from Push Gaming.
The math honesty note
A board that's nearly full can feel like the next respin will finish it. It won't necessarily. Each respin is random. The excitement of a filling board is the product, so enjoy it for what it is and stop at your limit.
Who it suits
Experienced players with a fixed budget who enjoy one long, involving bonus round more than frequent small wins. Set a deposit limit before you start, and treat every buy as money you can lose.
What to check in the info panel
Read the list of special symbols and what each does, the RTP for the base game and for each buy, the buy prices at your bet, and the max win. The symbol list is the most useful part, because it tells you what a good board needs.
Who should skip it
Anyone on a small budget, anyone who buys bonuses to recover a loss, and anyone who wants frequent wins. If you'd like to learn the respin idea with milder swings, try a collector game like Big Bass Bonanza first.
