The team at Relax Gaming are crying ‘All aboard’ as the Money Train 4 slot has arrived and is set to be the last segment in this well-known series. Set in a desert landscape, you are met with the same familiar train that kickstarts all previous editions, but boy has it gotten an upgrade! Big, bold, and post-apocalyptic, this train is one of the future.


Landing on a 6x6 playing grid aptly adorned with steel skulls; symbols include the lower-paying card suits of hearts, clubs, spades and diamonds, and the high-paying variety of human characters, some of which you’ve seen before.

The Money Cart bonus feature holds the goods this series is known for, offering a wide array of special feature symbols that bring 21 reel modifiers to the table. Re-spins and bonus buys also make a reappearance.

This feature makes a comeback, with its activation occurring randomly after any spin. In a re-spin, the highest-occurring symbols on the grid will stick, whilst the remaining get another chance at fate as they spin once more. In the re-spin, multiplier symbols might appear which will award you yet another re-spin. If you get more than one multiplier symbol, their values are added together and multiplied against your final win.
End of sticky symbols = end of round.

The money cart bonus is activated when three or more scatter symbols appear on the reels. Scatter symbols can be substituted by persistent symbols, awarding a win multiplier as well as three re-spins at the start of the round. If you trigger the bonus using a Persistent symbol, its special feature gets activated before the first spin.


Bonus rounds can see the grid expand to a maximum of six reels and eight rows. That’s four rows more than the base game. The key to unlocking new rows is to land a full row of symbols or through reel modifiers, of which there are 21 to choose from. These include bonus symbols which award a multiplier between 1-10 times the original bet. The payer presents a value and adds it to all symbols on the grid. And the necromancer that brings two to seven used feature symbols back to life. The same symbol may be selected multiple times.

If you want to jump straight into the Money Cart bonus without having to wait for scatter symbols to land you can immediately activate the bonus rounds through the bonus buy feature. You can choose between the original buy feature and the persistent buy feature. The first costs 100 coins and gives you standard access to the bonus rounds, while the latter costs 500 coins and guarantees a persistent symbol. This can only be activated in the appropriate regions and is not available in the UK.

Money Train 4 uses a scatter pay system - land eight of the highest-paying symbols or 10 of any other kind, and you’ve got yourself a winning combination. Although there is no wild symbol, the amount of modifiers and re-spins will make sure you have satisfying gameplay.

With this train’s final journey offering passengers the chance to win a maximum of 150,000 coins - it’s a futuristic ride worth strapping in for!

To ensure you don’t go off the rails, Relax Gaming has given this version’s interface an upgrade. You can find the game’s information, options and audio menus by clicking the three-lined button on the control bar at the bottom of the grid.

You can set your bet by adjusting the ‘-‘ and ’+’ buttons accordingly, before hitting the spin button to play. The game can also be enjoyed on both Android and iOS. It adapts its interface perfectly to fit smaller screens and can be played in both landscape and portrait mode.
