How to Win Mars Attacks

The key to winning big on Mars Attacks is getting that little bit of luck needed to trigger the lucrative bonus features. However, some symbols will contribute more to your pot than others The Mars Attacks logo symbol can help you reach the top prize of 500x your stake, while the green skull Wild pays out the same amount. 

Special Features & Bonuses 

As we’ve come to expect with Blueprint slots, Mars Attacks is bursting with bonus features, including five modifiers that can be triggered randomly during the base game. Here's how you can activate each feature: 

Base Game Modifiers 

  • Radiation Blaster: Random wilds pop up on the reels.
  • Mega Shrink Ray: The reels are shrunk meaning each reel now has 5 symbols, creating 3125 ways to win
  • Abduction Beam: the mothership takes all the symbols off the reels and replaces them with new ones cascading onto the reels
  • Expansion Cannon: A mystery symbol is added to the reels and expands to cover adjacent positions. All other Mystery Symbols will also be changed to match
  • Sub Zero Lazer: all winning symbols are frozen in place and re-spins are granted until the win can’t be bettered

Landing three or more Bonus symbols anywhere on the reels will trigger one of five bonus rounds. If you land four or more, the lowest-paying bonus round, Spy Hunter, will be eliminated from the selection so the lowest-paying bonus you will get will be We Come in Peace. 

The bonus round is determined by which zone you choose from a world map - Europe, Asia, Africa, Australia and America (North and South). The zone will be invaded by aliens, triggering one of the bonus rounds described below. 

Spy Hunter

Play ‘Martians or Human?’ from a list of suspects and earn a cash multiplier for every Martian you expose. If you find three Humans, you can collect your winnings and return to the base game. If you unveil the Martian Ambassador, you can earn a Big Money Boost, increasing your prize and ending the feature.

We Come In Peace

Pick from the containers to fill the banks at the sides of the screen. When a bank is filled, its value will be added to the bonus winnings panel and you will get either:

Multiplier: A multiplier value will appear in the bank, the bonus round continues.

Big Money: Once a bank is full it may award a Big Money Boost to improve your winnings and end the feature.

DNA Analysis

You will be taken to a new screen, where five Free Spins will be played out on 5x4 reels. Expanding DNA Wilds can be triggered throughout Free Spins to boost your win potential. 

When the reels are in motion, an overlay of these DNA Wilds will scroll down them. When the Wild symbols stop, any symbol position covered by a DNA Wild will be used as a Wild Symbol for that spin. DNA Wilds will expand by one symbol after each spin.

Martian Takeover

You will get Ten Free Spins to play on a 3x5 reel set with active Roaming Wilds. You can potentially land the Roaming Robot Wild on any reel on any spin. This special Wild not only substitutes for all other symbols but also fills the entire reel. 

It might move one reel to the left on each spin. If it reaches the furthest-left reel, it will be removed for the next spin. The feature ends after the tenth spin, regardless of how many Roaming Robot Wilds are on the reels.

Final Stand

Here, you get unlimited Free Spins on a 3x5 reel set. Keep an eye out for the special Advance Symbol, as it may pop up on reel two for the Humans and reel four for the Martians. There are also two progress bars at the bottom of the screen - one for Humans and one for Martians. 

One section of one of the bars will be filled each time the Advance Symbol lands on the corresponding reel. Humans multiply wins and Martians remove symbols when you reach designated milestones on the progress bar. The first team to fill their progress bar wins, ending the feature. If the Humans conquer the Martians, you’ll earn a Big Money Boost, to be applied to your winnings.

Progressive Jackpot King Mechanism 

As a Jackpot King slot, Mars Attacks players contribute a percentage of their stake into a potentially supersonic jackpot. Any spin can trigger the bonus round, indicated by five crown symbols. You then need to collect as many crowns as possible, with 15+ needed to reach the Wheel King and spin for Big Total Bet Multipliers or even the Jackpot.

Mars Attacks Design & Theme

The Mars Attacks film was directed by Tim Burton and Blueprint has managed to capture the director’s distinctive style in this slot, Symbols include eyeballs, green skulls, Martians and the Mars Attacks logo, while the reels are set against a backdrop of the White House. 

Fun features include the abduction beam which clears the reels and replaces the symbols and lightning strikes when you land a winning combination. The eerie soundtrack also helps put you back in the film, or may just make you want to watch it again!

Mars Attacks RTP 

The Mars Attacks is 96.44% RTP meaning that for every £10 you wager you can earn, on average, that percentage. 

Our Verdict

Mars Attacks may not be quite as well known as some of the other films Blueprint has created slots of, such as The Goonies, but the game itself has all the ingredients to become a modern classic. 

With almost a dozen bonus features, plus a fun, perfectly executed theme and a potentially stratospheric progressive jackpot, it’s a highly entertaining game that should appeal to most players.
