  • Huge range of modifiers in bonus game
  • Last game in the Money Train series


Buckle up, folks. Relax Gaming has released the fourth and final edition of the Money Train slot series with a title aptly named Money Train 4: The Final Stand. Each game in this series has taken players through some form of crisis, and this one is no different - you are going off-world to face some calamity with futurist weapons.

If you thought Money Train 3 had a lot going on - just wait until you see what this slot offers! Like the other Money Train titles, the gameplay is highly volatile, but this time, players can look forward to the largest top prize of the series - 150,000x the bet and a scatter pay system.

In the base game, a Respins feature can be randomly triggered at the end of every spin. With expanding rows, multipliers and over 21 modifiers, things get taken to a whole new level of gameplay. As you can clearly see from our intro, there is much to unpack here, so let's get going with our Money Train 4 slot review.

Theme and Graphics

Every Money Train game has a unique theme, but as the title suggests, the train is at the center of the game. Money Train 1 was the Wild West. Money Train 2 was more steampunk with a touch of the Wild West, and Money Train 3 was far more futuristic with a hint of steampunk. In this Money Train 4 slot, some earth-destroying event has occurred, and players now find themselves on another planet with a new, intimidatingly huge futuristic train armed to the teeth at the center of the gameplay.

Being the last slot of this series and with super impressive predecessors, Relax Gaming has gone all out with this game's graphics, animations and soundtrack. It is nothing short of cinematic and could easily rival any video game out there.

The game opens with an intense clip and then onto this new planet, barren, dry and sandy, where the monstrous shiny steel train stares you in the face. The 6x6 grid is flanked by creepy-looking skulls.

Symbols consist of human characters as the higher payers and card suit symbols as the lower payers. The scene changes dramatically when the Money Cart Bonus Round is triggered; with the playing field starting on a 4x6 grid, it's now nighttime with rain falling, fires blazing and some damage to the train where an intense battle is clearly underway.

Money Train 4 Slot RTP and Variance

The Money Train 4 slot by Relax Gaming has a variance score of 5/5, which means it comes with a high volatility rating. And it comes with a top win amount of 150,000x the stake.

This game has a fairly average base game RTP of 96.10%.

How to Play

Ready for your final stand in Money Train 4: The Last Stand? This time, Relax Gaming has updated the controls with a new layout from the previous 3 games, and it does seem like an improvement.

  • After launching the game and watching the cut scene, head for the menu button with the three lines with the information, options and audio menus.
  • Adjust your stake using the “-” and “+” buttons to the right of the menu
  • Start your Money Train 4 slot adventure by using the spin button

How to Win

The Money Cart 4 slot has a grid that consists of 6 reels and 6 rows compared to its predecessors, which had a 5x5 grid setup. This game uses a scatter pays system, which awards a payout when at least 8 of the two highest-paying symbols land in view or 10 of any of the other symbols hit simultaneously.

One symbol you will not find in this game is the Wild symbol; however, there are more than enough modifiers and respins to compensate for this missing symbol – more on this shortly.

The betting range for Money Train 4 starts at £0.10.

Just like Money Train 3, the respin bonus in the Money Train 4 slot is triggered randomly after any spin. The most present symbol on the grid will stick, and all the other symbols will respin. During the respin feature, multiplier symbols can land, adding to the increasing multiplier meter and awarding a respin just like the sticky symbol. However, these symbols do not remain sticky but will award a respin.

The round ends when no more of the sticky symbol lands.

Bonus Round

The Money Cart bonus round is triggered by landing 3 or more bonus symbols anywhere on the reels. And let’s be honest here. This is the one feature we all come to play this series for, and it does not let us down. The gold bonus symbol (persistent) can substitute for any bonus symbol. Once the round starts, the bonus symbols will award a multiplier, and 3 respins will be awarded.

The persistent symbol will award a modifier that remains sticky on the reels during the respins and acts at the beginning of each spin.

The bonus round starts on 6 reels and 4 rows, which can expand during the course of the round up to a maximum of 6 reels and 8 rows – that’s when the payouts start to ramp up! New rows can be unlocked by filling a row with symbols or through a modifier, and any newly unlocked rows will immediately activate the action of any symbols found within.

The Money Train 4 slot bonus round modifiers are:

  • Bonus Symbols – awards a multiplier of 1 to 10 times the initial wager.
  • Collector – gathers all displayed values and adds them into its own total.
  • Persistent Collector – accumulates all visible values, adding them to its total when the current spin ends and any subsequent spins – it does not take on its own value.
  • Adjacent Collector – adds all nearby values from adjacent positions into its own total.
  • Persistent Adjacent Collector – collects neighbouring values in each spin, adding it to its own total during that spin and each spin thereafter.
  • Payer – reveals a value and adds it to all other visible symbols.
  • Persistent Payer – exposes a value and adds it on to all other displayed symbols during the current spin and following spins, excluding itself.
  • Adjacent Payer – reveals a value, then adds it to adjacent symbols.
  • Persistent Adjacent Payer – reveals a value, then adds it to adjacent symbols in the current spin and each spin thereafter.
  • Sniper – will double the values of 3 to 8 Bonus symbols, potentially targeting the same Bonus symbol multiple times.
  • Persistent Sniper – will double the values of 3 to 8 different Bonus symbols during the current spin and following spins, capable of selecting the same Bonus symbol more than once.
  • Collector Payer – selects 3 to 5 symbols as targets, adds the values into its own, and adds the updated value to each of the selected targets.
  • Persistent Collector Payer – after each spin, selects 3 to 5 symbols as targets and adds the values into its total, which then pays the updated amount to each target.
  • Arms Dealer – transforms 1 to 4 Bonus symbols into a feature symbol; the newly formed feature symbol then performs its action.
  • Persistent Arms Dealer – converts 1 Bonus symbol into a feature symbol at the end of a spin and each spin thereafter, which then performs its unique action.
  • Necromancer – resurrects 2 to 7 previously used feature symbols, possibly targeting the same symbol multiple times.
  • Persistent Necromancer - resurrects 1 to 7 previously used feature symbols at the end of the current spin and every spin afterwards, potentially reviving the same symbol multiple times.
  • Persistent Shapeshifter - Transforms into any one of the following features after each spin: Collector, Sniper, Payer, Arms Dealer, Collector Payer, or Unlocker.
  • Unlocker – releases a locked row.
  • Reset Plus – raises the initial spin count by +1.
  • Upgrader – Upgrades 1 to 3 feature symbols to the Persistent versions.

Money Train 4 Review – Our Verdict

Wow, what can we say other than Money Train 4: The Final Stand is simply the perfect slot to end the Money Train series, and honestly, we didn't expect anything less from Relax Gaming.

Even if you weren't somehow a fan of this series or aware of the other titles (Relax has spin-off slots called Money Cart 2 and Money Cart 3), the outstanding audio-visuals and the top prize of 150,000x offered in this Money Train 4 slot would be enough to pique your interest.

Since the first release, the Money Train slots have been all about the Money Cart bonus round. This time, for one last swan song, it comes packed with a huge 21 modifiers, multipliers, and expanding rows, making this slot one of the most dynamic games ou there.

It may stay like that for some time to come, too, because that’s what the Money Train series is all about: pushing the barriers further with each release. Most studios fail at the tricky follow-up title, but Relax Gaming has managed to give us something better four times on the bounce.

Hats off to the team for a job well done. We’ll look forward to whatever they have in store next!
