Step 2: How To Play

  • Press 'SPIN' to start the game.
  • The reels will spin and eventually stop at random.
  • If the combination of symbols appearing on the reels forms a line of 2, 3, 4 or 5 matching symbols (starting from the left) on one of the win lines, then you win. Any winning lines you have will be highlighted and your winnings will be credited to your account balance.

Reel Wins

  • All line pay symbols must appear on a played line and on consecutive lines beginning with the far left reel.
  • Only the highest line win is paid on each line.
  • Scatter wins are added to any line wins.

Wild Symbol

  • The Wild(s) symbol can be used to help form line wins by substituting for other symbols.
  • The Wild(s) symbol substitute for all symbols except scatter symbols or bonus symbols.
  • Only the highest paying win on each line is paid (for example 3 wild symbols being a win or those symbols being used with another symbol to make a win of 4 symbols will only pay which of those two is the highest).
  • Wild symbols include: Skeleton Wild, Expanding D.N.A. Wild and Roaming Robot Wild.

Mars Attacks Modifiers

  • The Mars Attacks Modifiers can be triggered randomly during any spin:

  • Abduction Beam - The symbols on the reels will be taken away by the Mothership and a new reel set will cascade onto the screen.
  • Expansion Cannon - A Mystery Symbol will be placed onto the reels which will begin to spread to nearby positions, eventually all Mystery Symbols in view will transform into a randomly selected symbol.
  • Sub-Zero Lazer - Winning symbols will be frozen in place and the reels will re-spin, the reels will continue to re-spin until the win is no longer improved.

Bonus Activation

The player enters the bonus by achieving 3 or more bonus symbols anywhere in view. There is no payout awarded directly for getting this, just entry to one of the bonus rounds.

If 4 Bonus Symbols land anywhere in view the lowest paying feature "Spy Hunter" will be automatically eliminated, meaning that the minimum Bonus that can be awarded is "We Come in Peace".

After achieving 3 or 4 Bonus Symbols the player will be taken to a new screen and prompted to "Pick a Zone" from a world map. The selected Zone will be invaded by UFOs and award 1 of the available bonus rounds.

The 5 Zones are:

  • Europe
  • Asia
  • Africa
  • Australia
  • America (North and South)

If 5 Bonus Symbols land in view the highest paying feature "Final Stand" will be automatically awarded and begin immediately.

Spy Hunter

Pick Suspects from a board to reveal Martians or Humans. Every Martian revealed will award a cash multiplier. Revealing 3 Humans will COLLECT the current bonus winnings. Finding the Martian Ambassador will award a BIG MONEY boost to your winnings and end the feature.

We Come In Peace

The player selects from containers which fill the banks at the sides of the screen. Once a bank has been filled its value will be awarded in the bonus winnings panel and 1 of the following will be presented:

  • MULTIPLIER: A new multiplier is displayed in the Bank and the feature continues.
  • BIG MONEY: When filled again awards a BIG MONEY boost to your bonus winnings and ends the feature.

A special 'UPGRADE ARROW' can be revealed when selecting a container which will improve all cash multipliers on screen.

The feature ends when the player reveals the 'Martian Orb' which explodes and collects the bonus winnings.

D.N.A. Analysis

The player will be taken to a new screen and awarded 5 Free Spins on a 4x5 reel set with Expanding D.N.A. Wilds active.

An overlay of D.N.A. Wilds will scroll down the reels as they spin. The D.N.A. Wilds will eventually come to a stop. Any position covered by a D.N.A. Wild will be considered a Wild Symbol for that spin.

After each spin all D.N.A. Wilds will expand by 1 symbol height.

Martian Takeover

The player will be taken to a new screen and awarded 10 Free Spins on a 3x5 reel set with Roaming Wilds active.

Each spin has a chance to bring in a Roaming Robot Wild on any reel. This fills the entire reel and substitutes all symbols. After each spin the Roaming Robot Wild will move one reel to the left.

Once the Roaming Robot Wild reaches the leftmost reel, on the next spin it will be removed. The feature ends on the last spin regardless of how many Roaming Robot Wilds remain on screen.

Final Stand

The player will be taken to a new screen and awarded unlimited Free Spins on a 3x5 reel set.

On any spin a special Advance Symbol can appear on reel 2 for the Humans and reel 4 for the Martians. Either or both of these symbols appearing will cause their respective progress bar at the bottom of the screen to fill by 1 segment. The Humans will multiply wins and the Martians will eliminate symbols at specified milestones of the progress bar. The first progress bar to reach the final segment will end the feature.

If the Humans win the player will be awarded an additional BIG MONEY boost to their winnings.

Feature Gamble

Whenever a Feature win is achieved in the game (except for Final Stand), the player has the option to either COLLECT the feature or Gamble to try and win one of the other features in the game.

After the award of the initial Bonus, the player will be presented with a Gamble screen showing the 5 features from bottom to top, ranked in terms of average payout. The feature the player has won will be shown to the player with the words COLLECT and GAMBLE shown on the feature panel in the centre of the screen.

If the player gambles and wins, the feature they have gambled to can be collected, with all features below that now eliminated. This continues until the player collects, reaches the top feature (where it awards that feature) or the player receives "DEFEATED" when selecting a Zone where they are then awarded a Mystery Win Prize (a mystery cash value based on a multiplier of the player's total bet).

The odds of winning during the gamble feature are not necessarily the odds shown.
