Money Train 4: Theme, Presentation, and Music
Money Train 4 boasts the best visuals in the series so far, with incredible attention to detail, sharpness, and an eye-catching environment. The game transports you to a distant world with more of the robotic elements seen in Money Train 3, only this time it’s all a little brighter and more colorful.
The background showcases a vast desert landscape with multiple moons or other planets visible in the clear sky. An android’s head and torso have been mounted on a spike, and the titular train is a heavily armored beast with cannons mounted across it.
How about the sound? Money Train 4’s music has an exciting, cinematic quality that suits the apocalyptic sci-fi theme brilliantly.

How to Play Money Train 4
Money Train 4 features a 6x6 grid with a scatter pays mechanic. Instead of landing symbols on fixed paylines to win, payouts are awarded for a specific number of identical symbols appearing anywhere on the grid at the same time. The top two symbols award prizes for eight or more, but the rest require at least 10 for a win.
Before you start playing, take a moment to set up your stake: use the ‘-’ and ‘+’ buttons to adjust your bet from the default amount. Bets range from $0.10 to $6.00.
When you’re ready to dive in, push the ‘spin’ button to get started. To check the paytable, tap the menu button followed by the ‘i’.
Money Train 4 Symbols and Payouts
Money Train 4 has eight standard symbols: four characters and four card suit symbols. The characters are an older man with a cigar, a Native American man, a man in a sombrero, and a cowgirl with red hair. The older man awards the top prize on the paytable: get 36 anywhere to win 1,000x your bet.
As well as these, several special symbols can hit the reels in the Money Cart bonus round. Here are the payouts for all standard symbols in Money Train 4:
Money Train 4 Volatility and Return to Player
Money Train 4 is highly volatile, and I found that payouts were fairly regular. While most were small, the Respin feature helped award bigger wins thanks to the multipliers. These weren’t massive by any means, but still much better than the standard payouts.
The theoretical Return to Player (RTP) is 96.10%, so it’s a little over the average.
Bonus Features in Money Train 4
As with the other Money Train slots, Money Train 4 has strong bonuses. There are only two, but the Money Cart bonus round includes various special symbols that can help you win in different ways.
Respin Feature
The Respin feature may trigger at the end of any spin. The symbol that appears most on the reels during the triggering spin will become sticky, and one respin will be awarded. Multiple symbols of the sticky type can appear during respins.
Multiplier symbols can land, too. These won’t stick, but will trigger one more respin. Multipliers will be combined and multiply the win amount at the end of the respin sequence. Respins will end when no new symbols appear.
Money Cart Bonus Round
If you land three or more Bonus symbols anywhere, you’ll trigger the Money Cart bonus round. The Persistent symbols may substitute for Bonus symbols to activate this feature, too.
When the round starts, the triggering symbols will reveal a value shown as a multiplication of your bet and you’ll receive three free spins.
Each time you fill a row with symbols, one extra row will open and symbols in this row will take their specific action. You may add up to four extra rows in total. You can land extra symbols in this round, including:
- Bonus: Has a value of 1x - 10x your bet.
- Collector: Collects all values on the grid and adds them to its value.
- Persistent Collector: Collects all values and adds to its own value at the end of the current spin and the rest in the round. It won’t collect its own value, though.
- Payer: Reveals a value as a bet multiplication, then adds this to the value of all other symbols on the grid.
- Sniper: Doubles the values of three to eight other bonus symbols.
Additional bonus symbols include Necromancer, Unlocker, and Reset Plus.
Buy Feature
TYou can pay 100x or 500x your bet to trigger the feature as normal or start it with one Persistent symbol, respectively.

Respins are another great addition, especially when multiplier symbols start boosting the size of payouts. Money Train 4 shines in other areas, too. The visuals are superb and bring the otherworldly setting to life vividly, and the graphics undergo a big change when the Money Cart round triggers.
The various symbols can award generous wins even without help from multipliers, but you’ll need to pack a lot of them onto the grid to scoop the top values (e.g. 1,000x your bet for 36).
Overall, Money Train 4 is an outstanding slot, sure to satisfy fans of the series and newcomers alike.
