Mars Attacks Slot Special Features

Mars Attacks Modifiers

One of Five modifiers may be randomly triggered on any spin.

Radiation Blaster
Wilds will be placed on the reels in random positions.

Mega Shrink Ray
The reels will be shrunk, meaning five symbols appear in each reel. Wins will then be paid for any consecutive symbols, from left to right, regardless of position.

Abduction Beam
Symbols on the reels will be removed by the Mothership and a new set will cascade onto the screen.

Expansion Cannon
A Mystery Symbol will be placed on the reels before spreading to cover nearby positions. All Mystery Symbols present will be turned into the same, randomly selected symbol.

Sub-Zero Laser
Symbols involved in a winning combination will be frozen in place and the reels will respin until the win cannot be improved.

Mars Attacks Bonus Rounds

Land three or more Bonus symbols anywhere on the reels to be granted entry to one of five bonus rounds. If four Bonus symbols are involved in the triggering combination, the lowest paying feature, Spy Hunter, will be eliminated from the list of bonus rounds on offer. This means that the minimum bonus feature that can be awarded is We Come in Peace.

You will be taken to a new screen, from which you’ll be instructed to choose one of five zones from a world map. These zones are Europe, Asia, Africa, Australia and America (North and South). The zone you pick will be invaded by aliens and one of the following bonus rounds will be triggered.

Spy Hunter
Pick from the suspects on the board - are they Martians or Humans? A cash multiplier will be awarded for every Martian you expose. Find three Humans and you’ll collect your current winnings and return to the base game. Discover the Martian Ambassador and get your hands on a Big Money Boost which will increase your prize and end the feature.

We Come In Peace
Choose from the containers to fill the banks at the sides of the screen. If a bank is filled, its value will be added to the bonus winnings panel and one of the following will be given to players:

Multiplier: A multiplier value will appear in the bank and the bonus round continues.
Big Money: When filled again, a bank may award a Big Money Boost which will be applied to your winnings and ends the feature.

DNA Analysis
A new screen will appear and you’ll be awarded five Free Spins to be played out on a 5x4 reel setup. Expanding DNA Wilds are active throughout Free Spins which could see your winning potential grow. An overlay of these DNA Wilds will scroll down the reels when they are in motion. These Wild symbols will eventually come to a stop, and any symbol position covered by a DNA Wild will be considered a Wild Symbol for that spin. DNA Wilds will expand by one symbol after each spin.

Martian Takeover
Ten Free Spins will be awarded on a 3x5 reel set and Roaming Wilds will be active. Each spin brings a chance to land a Roaming Robot Wild, which can appear on any reel. This special Wild fills the entire reel and can substitute for all other symbols. The Roaming Robot Wild may also move one reel to the left each time the reels are spun. Should the Roaming Wild reach the leftmost reel, it will be removed for the following spin. The Martian Takeover feature ends after the last spin, regardless of how many Roaming Robot Wilds remain on the reels.

Final Stand
The Final Stand awards unlimited Free Spins on a 3x5 reel set. Look out for the special Advance Symbol, as it may appear on reel 2 for the Humans and on reel 4 for the Martians. You’ll also find two progress bars at the bottom of the screen - one for Humans and one for Martians. These bars will be filled by one segment each time the Advance Symbol lands on the corresponding reel. Humans will multiply wins, whilst the Martians will remove symbols when specified milestones are reached on the progress bar. The first team to fill their progress bar wins, and the feature ends. Should the Humans conquer their alien enemies, you’ll be awarded a Big Money Boost, which will be applied to any winnings achieved.

Feature Gamble

You have to option to gamble any feature wins achieved in Mars Attacks slot (except for Final Stand). Choose Collect to claim the feature, or Gamble to try and win a higher-paying one. Upon triggering the initial Bonus, you’ll be presented with the available bonus rounds, ranked according to average payout. The feature you’ve won will be displayed on screen. If your gamble is successful, you can continue to gamble to until you choose to collect or you are awarded the top-paying feature. If the word ‘Defeated’ appears that means you’ve lost your gamble and will be awarded a Mystery Win Prize instead.

Jackpot King Progressive

Mars Attacks slot is plugged into the Jackpot King Progressive, meaning that a percentage of each stake placed by all players is added to the progressive pot. The Jackpot King can be triggered at random by any spin at any stake - you’ll know you’ve entered this bonus as five crown symbols will appear on the reels. After any spin you may choose an item, which can reveal prizes to help you progress through the feature. The aim is to accumulate as many golden crowns as possible - land fifteen or more to spin the Wheel King. The Wheel King awards Big Total Bet Multipliers or possibly the Jackpot King itself, which is often a huge sum of money.
