    Invaders Megaways Online Slot Game

    You can play Invaders Megaways from just 25p per spin.

    This game uses the Megaways mechanic, and features 1,000,000 paylines.

    Wild Symbols 

    All symbols, except for Bonus symbols, can be replaced by Wild symbols in the main game.

    During the Logo Modifier, the Bonus symbol can be replaced by an expanded Wild symbol.

    Bonus Symbols

    If four or more Bonus symbols appear, then the Free Spins Bonus will activate and up to 15 free spins will be awarded.


    In this game, symbols can be of different sizes.

    The number of Megaways for each spin is displayed when the reels stop spinning.

    Each reel can display two to ten symbols during the main game and the Free Spins Bonus.

    Symbols involved in winning combinations will explode and new symbols will fill the empty spaces.

    Wins are evaluated before the symbols explode, with any new wins evaluated once the new symbols appear.

    Once no more cascades occur, the total amount won for that spin will be awarded.

    UFO Wild Selector 

    In the main game, a random symbol may be chosen by the UFO to act as a Wild symbol.

    When this happens, all instances of the chosen symbol on reels two to five will act as a Wild symbol for the entire spin.

    During the Mythical Unicow feature and the Free Spins Bonus, this can happen on the chosen symbol across all reels.

    Mythical Unicow Feature 

    If the Unicow appears during the main game, all reels will display seven to ten symbols each.

    Free Spins Bonus 

    To trigger the Free Spins Bonus, at least four Bonus symbols must appear on the reels.

    The number of free spins awarded depends on the number of triggering Bonus symbols.

    It is possible to receive four extra free spins if three Scatter symbols appear during the bonus.

    A random picture symbol is selected to be a Wild symbol for the entire free spin in this bonus.

    Depending on which symbol is chosen, one of the following modifiers will be played:

    LogoAll visible Logo symbols expand to fill the entire reel. Expanded Logo symbols act are evaluated as multiple smaller symbols.
    ScientistAll Scientist symbols are transformed into Wild symbols. A win multiplier, worth x2-x256, doubles every cascade.
    AlienEvery reel containing an Alien symbol grows in height. Adjacent reels also increase in height.
    CowAll Cow symbols transform into a x2 Wild symbol, which is evaluated as two Wild symbols when considering wins.
    Ray GunOne Wild symbol is added to the reels for each Ray Gun symbol visible on the reels. Additional Wild symbols are not added as a result of new Ray Gun symbols that cascade in.

    The Free Spins Bonus uses the same bet value and winning combinations as the triggering spin.

    Free spins are played automatically and end if the maximum win has been achieved.

    The bonus ends when there are no more free spins left to play. 

    Return to Player 

    Return To Player (RTP): 96.30%

    For example, if we take £100 of wagers we will, on average, pay out £96.30 of wins.
