Money Train 4 Slot Review: 150,000x Max Win Masterpiece

Why this Money Train 4 slot review ends on a high score

This Money Train 4 slot review looks at the last chapter of one of the most influential slot series of the past few years. Relax Gaming released it on 20 September 2023.

The setting is a dystopian, sci-fi take on the Wild West. Bandits, a sheriff and a tangle of mechanical hardware sit on a 6x6 grid.

We score it 9.8 out of 10 and rate it a ReelRadar Masterpiece. Our house view favours high volatility and a large win ceiling, and Money Train 4 delivers both.

Money Train 4 slot review: how the base game plays

There are no paylines and no wild symbol. It is a scatter-pays slot, so matching symbols pay wherever they land on the 6x6 grid.

The base game is not where the big money lives, but it is not dead either. Wins are modest and often feel like a holding pattern.

Stakes run from 0.10 to 6.00 per spin. That range is friendly to small bankrolls, though high rollers will find the ceiling low. Money Train 4 is built around a multiplier ceiling, not a big stake.

The Respin feature

The Respin feature can fire at the end of any spin, including a losing one. Symbols of the most common type lock in place and the rest of the grid spins again.

It works as a mid-game booster. It gives dead spins a second chance and adds some drama to the base game. It also breaks up the wait between bonus rounds, which matters in a game this volatile.

Money Cart bonus and the special symbols

Money Cart is the main event. Land three Bonus symbols to trigger it. A persistent symbol can also act as one. The round starts with a pre-loaded grid of values and gives you three spins.

Every time a new symbol lands, the spin counter resets to three. Chains can run on far longer than the opening three spins suggest.

The round has more than 20 feature symbols, and this is where the game gets its depth. Payers add values. Collectors gather the values around them.

A lot of the fun is working out how the symbols combine. A persistent Collector next to a stack of Payers can turn a small round into a large one.

The round ends when the spins run out or when the total hits the cap. If a round passes 150,000x, the game stops and pays exactly that amount.

Money Train 4 bonus buy options

Our database lists no bonus buy for this slot. The provider's own details say otherwise. Where it is allowed, players can pay 100x their stake to enter Money Cart directly.

Availability depends on your casino and jurisdiction. Some regions do not allow bonus buys at all, so check the game's info screen before you plan around one.

The cost of buying in is steep, and the round is still very volatile. A 100x buy can return less than you paid, and often does.

Money Train 4 RTP, volatility and max win

The Money Train 4 RTP is 96.10% in the standard game, which is average for the industry. Operators can switch to lower-return versions.

Volatility is high, and at the upper end of high. Expect long stretches of small returns. Larger hits arrive in bursts, and most of them come from the Money Cart round.

The Money Train 4 max win is 150,000x your stake, the highest in the series. For comparison, the third game capped at 100,000x. At the 6.00 top stake that ceiling works out to 900,000.

Treat that number as a ceiling and not a target. The odds of reaching it are very small, and the provider has not published an official figure. Most big rounds finish far below it.

Money Train 4 demo and free play

Money Train 4 free play is the best way to learn this game. The feature symbols interact in ways that are hard to follow from a description.

Use the demo to get a feel for the swings. Note how long dry runs last and how often the Respin feature appears. Then decide whether the pace suits your budget before moving to real stakes.

If you play for real, use small bets and set a hard session limit. High volatility rewards patience, but it punishes oversized stakes.

Why it earns 9.8 out of 10

Most of the score comes from the two things we weight most: volatility and max win. Money Train 4 sits at the top of both.

The RTP is average, so it adds only a small share of the score. Our editorial rating covers theme, pacing and bonus design. The theme is strong and the pacing is smooth.

It is not for everyone. Players who want frequent mid-sized wins or a simple rule set may find it too demanding. For anyone who likes volatile, feature-heavy slots, it is a benchmark.
