Money Train 4 is the final chapter in Relax Gaming's Wild West train-heist saga, released in 2023. It keeps the outlaw crew but changes the core mechanics: instead of paylines, wins form through scatter pays on a 6x6 grid. The most distinctive feature is the Money Cart bonus, which can deliver the game's top prize of 150,000x your stake.

The basics: layout, studio and how wins form
Money Train 4 is built on a 6x6 grid that uses scatter pays — matching symbols anywhere on the reels create a win, with no paylines to worry about. During the bonus round, the grid can expand up to 6x8, giving more room for symbols to land.
Relax Gaming developed the game, and it continues the train-heist theme from the earlier Money Train titles. The expanded outlaw crew is part of the theme, though the mechanics are what set it apart from a standard 5x3 pokie.
The scatter-pays format means you don't need symbols to align on a line; any position counts, which changes how you read the board. The grid starts at 6x6, and the expansion to 6x8 only happens inside the bonus, so the base game is a straightforward grid with scatter wins.
Setting up a spin: stakes and controls
To play Money Train 4, set your bet using the selector, which ranges from $0.10 to $6.00 per spin. The game uses a 6x6 grid with scatter pays, so wins are formed by matching symbols anywhere on the reels — there are no paylines to line up. The paytable and game information are accessible via the info button, usually located near the bet selector. After adjusting your bet, press the spin button to start the round. If you want to skip the base game, you can use the bonus buy option, which costs 100x your bet and takes you straight to the Money Cart bonus. There is also a 500x bet version that includes one persistent symbol. Choose the standard bet if you prefer to trigger the bonus naturally, or switch to the bonus buy if you're willing to pay for immediate access.
The features that do the heavy lifting
The key features in Money Train 4 are:
- Respin feature – sticky symbols and multiplier accumulation during respins.
- Money Cart bonus – triggered by 3 or more scatters, with 20+ special symbols including Collector, Payer, Sniper, Arms Dealer, Necromancer, Shapeshifter, Upgrader, and Unlocker.
- Bonus buy – costs 100x your bet to enter the bonus directly.
- 500x bet version – a higher-priced bonus buy that includes 1 persistent symbol.
The respin feature can build a win by keeping symbols locked while multipliers add up. For example, a Collector symbol might gather values from other symbols during respins, increasing your total. The Money Cart bonus is where the big payouts come from, with the special symbols each doing something different to boost the final result.
Session limits, bet sizing and the myths
Given the high volatility, your bankroll needs to survive long dry spells. With a bet range of $0.10 to $6.00, a $50 session should use bets around $0.50 to $1.00, giving you 50 to 100 spins. A $200 session can handle $2.00 to $4.00 bets, which still leaves room for variance.
The bonus buy costs 100x your bet, so at a $1.00 stake that's $100 per attempt. The 500x version costs $500 at the same stake. These are expensive, so only consider them if your bankroll is large enough to absorb a few misses.
No betting system changes the RTP; the game's maths is fixed. The only real control you have is bet size and how often you buy the bonus.
RTP versions, variance and the top prize
The default RTP is 96.1%, but there are two versions: 96.10% for the standard game and 96.50% with the bonus buy. That difference means for every $100 wagered, the 96.50% version returns an extra $0.40 on average compared to the 96.10% version.
The maximum win is 150,000x your stake. At a $0.10 bet, that's $15,000; at the $6.00 max bet, it's $900,000. The game is high volatility, so wins are less frequent but larger when they land.
Always check the RTP version in the game's info panel before you play, as it can vary by operator.
Demo mode vs real money
The demo version of Money Train 4 uses play credits but runs the same maths and RTP as the real-money build at the casino you open it in. For a high-volatility game like this, a demo session is useful for seeing how often the Respin feature and Money Cart bonus trigger, and for getting a feel for how bet size affects your bankroll across the $0.10 to $6.00 range. You can test different bet levels without financial risk. When you switch to real AUD, bets become real and your session limits matter — the demo won't prepare you for the emotional weight of losing actual money, but it does help you understand the game's rhythm.
Where to play Money Train 4 for real money in Australia

Verdict
Money Train 4 suits players who enjoy high-volatility games with the potential for massive wins, especially those who like bonus-buy mechanics. It's not for casual players or those with small bankrolls, as the base game can be quiet. The main downside is the high cost of the bonus buy, which can drain a session quickly if luck doesn't hold.
Alternatives on this site
Money Train 3 — Both are Relax Gaming train-heist pokies with a Respin feature and Money Cart bonus. Money Train 3 uses a 5x4 grid with very high volatility and a 100,000x max win, while Money Train 4 expands to 6x6 scatter pays and raises the max to 150,000x.
Sweet Bonanza — Sweet Bonanza also uses scatter pays on a 6x5 grid, so the win-reading is similar. It has medium-high volatility and a 21,100x max win, which is much lower than Money Train 4's 150,000x. Its features are tumble and multiplier bombs, not a respin bonus.
Razor Shark — Razor Shark is a high-volatility pokie with a 50,000x max win, but it uses a 5x4 payline format. Its features are Mystery Stacks and Razor Reveal, which differ from Money Train 4's scatter pays and Money Cart bonus. Both are high-risk, high-reward games.
