Money Cart 4 Demo

A Sci-Fi Spectacular

Load the Money Cart 4 slot machine on your PC or mobile to enter a striking world of alien planets, blazing spacecraft, and a 6×4 grid of radioactive warning symbols. 6×2 sections above and below the main game sit within force fields, waiting to be unlocked by various characters and their weapons.

You’ll meet a crew of Western-style outlaws and futuristic guns in this Sci-Fi / Steampunk slot from Relax Gaming. Prepare for an adrenaline rush from the unconventional gameplay at the most popular online casinos highlighted here.

Choose Your Stakes

The betting range stretches from a minimum of 0.10 to a maximum of 60.00 per spin and you play with ten coins. It’s a high-volatility title with an average return of 96.0%.

Spin the reels and each symbol position turns independently to show either nothing or Bonus symbols. Land at least three Bonus symbols and the Money Cart 4 online slot springs into action.

Gather the Bonus Bandits

Don’t expect matching symbols across paylines, wilds, free spins, progressive jackpots, or other classic mechanics. That’s not how things operate in this part of the galaxy. Any triggering Bonus symbols reveal values from one to ten coins and lock in place for at least three respins of the remaining positions.

Any new Bonus symbols also lock in place, and a variety of modifier symbols boost their values. Here’s what each one does –

Collector – She gathers all symbol values and adds them to her own. Her futuristic gun is a Persistent Collector that repeats this for every remaining respin.

Adjacent Collector – She collects the values of any connected symbols on the reels of the Money Cart 4 slot machine, while a Persistent version repeats this on the current spin and all subsequent spins.

The Payer carries two guns, and this bandit reveals a value, then adds it to all visible symbols. The guns act as a Persistent Payer symbol that stays active for the rest of the feature.

He can also appear as an Adjacent Payer, adding his value to all connected symbols, and once again, there’s a Persistent version that remains active for the rest of the round.

Watch for the Sniper, who doubles the values of three to eight symbols, potentially targeting the same symbol multiple times. The Persistent Sniper repeats this on every remaining spin.

Characters can combine their powers for even bigger rewards. The Collector Payer selects from three to five symbols, then adds their values to her own before paying the upgraded amount to her targets. Once more, you can land a Persistent version of this symbol.

An Arms Dealer converts from one to four symbols into characters or weapons that then apply their modifiers, with the Persistent Arms Dealer staying active.

The leader of this crew is the Necromancer. He revives from two to seven non-persistent symbols and can do this several times. The Persistent version repeats this on every remaining spin.

Play the Money Cart 4 slot online and you may also encounter the Persistent Shapeshifter, who morphs into a feature symbol on every remaining spin.

The vault door Unlocker symbol opens up a new row above or below the reels to provide extra symbol positions. An Upgrader converts from one to three feature symbols into Persistent versions.

Respins continue until you get three consecutive spins with only blanks or fill the grid. Land the Reset symbol and it grants one extra life each time it appears, letting you survive four, five, or more spins without new symbols.

Other Adventures Among the Stars

Comparable games with more familiar mechanics include the Steampunk Bandits slot from Gameplay Interactive and the Space Battle slot by Fugaso.

Join the Fight!

Hit fewer than three Bonus symbols and nothing occurs, but once the respins begin, you’re guaranteed a win from the triggering symbols and, with luck, much more as the bandits join the fray.

It’s a rapid-fire feature and undeniably thrilling as you watch symbol values climb throughout. Play Money Cart 4 for free on this page to see it in action, then switch to real-money play at the top sites for potential payouts of 15,000x your stake!
