“Defend Earth from our extra-terrestrial enemies in this 5-reel 10-line slot that pays both ways! Blast Invaders with the laser cannon to turn them into multiplier wilds! Vaporise the UFO to win a re-spin with extra wilds! Keep winning to save the world in this arcade classic!”

Who would have thought it this time last year that 2016 would be the year of Playtech? But thanks to a few hefty kicks up the back side they have taken the online casino game world by storm this year and they don’t look to be slowing down at all. Next on their massive hit list for 2016 is a brilliant looking and highly original Space Invaders slot built in conjunction with the TAITO Corporation who brought us the original world famous classic arcade game Space Invaders way back in 1978. That was of course well before my time but such was it’s timeless appeal that it remained a popular staple of arcades across the world for a decade or more and goes down with Pacman and Pong in the top 10 arcade games of all time!

5-reel 10-line Slots

The objective of the Space Invaders slot is to obtain winning symbol combinations by spinning the reels.

To play the game:

  • Click Continue on the entry screen so that you can be directed to the main game reels.
  • The number of active paylines is permanently set at 10. Wins can form on any payline.
  • For information on paylines, click Info and go to the Paylines page.
  • There is a difference between the line bet and the total bet. The line bet shows how much is being bet on a single payline. The total bet shows how much is being bet in total on a single spin. Payouts shown in the paytable (on the Payouts screen) are multiplied by the line bet.
  • Choose your bet by clicking + and – below the Line Bet field.
  • Clicking Spin spins the reels with the current bet.
    • By selecting AUTO in the main game you can choose to place different numbers of bets automatically, one after the other. Select your bet as normal then tap the AUTO button to open up the Autoplay selection screen.
    • To start an Auto Play session, you must first set several parameters:
      • The number of Auto Play spins.
      • A maximum overall loss limit. When this figure has been bet and lost in an Auto Play session, the session will end.
      • A single win limit. When an Auto Play spin awards a win that is equal to or higher than this limit, the Auto Play session will end.
    • When these parameters have been set, press “CONFIRM” to start the Auto Play session. You can also press the “EXIT” button to close the Auto Play selection screen.
    • Automatic spins will stop if you trigger a feature, do not have enough funds for the next spin, or if either the maximum overall loss limit or single win limit are reached.
    • You can stop Auto Play from continuing onto the next spin by tapping the STOP button which replaces the AUTO button during the Auto Play spins.
  • Clicking the Turbo Mode button switches on or off the Turbo Mode thus turning on or off some of the win animations and sounds, and making the reels spin faster or slower.
  • Wins are calculated according to the paytable. Your win will equal your bet multiplied by the corresponding value according to the paytable.
  • On a given payline, only the highest winning combination pays while simultaneous winnings on different paylines are accumulated.
  • In the case of a winning spin, the Win field displays the accumulating winnings.

Info pages:

  • Clicking Info opens the reference pages describing the different game components.
  • Clicking the arrow buttons enables you to navigate between the pages.
  • Clicking the return arrow icon exits the Info pages and returns you to the game.



  • All 10 paylines are permanently active, and can be viewed from their page in the Info screen.

About Payouts:

  • Payouts are listed on the Payouts screen. To find the possible win amount for any given symbol combination, the line bet must be multiplied by the payout.
  • If 2 payline winning combinations occur on the same line, the higher of them is paid out. If more than 1 active payline has a winning combination, the winnings are accumulated.
  • Winning combinations can start from the leftmost reel or rightmost reel, and the same symbol has to be on every consecutive reel.

Maximum Win Limit

  • The maximum win in the game has an upper limit. For more information, see the Terms and Conditions section.

Invaders Turn Wild

  • The Cannon appears beneath the reels and may move to stop under a different reel during every spin.
  • The Invaders Turn Wild feature can be triggered when the Cannon stops beneath reel 2 or reel 4.
  • If there are Low Win (Invader) symbols above the Cannon they will turn into Wild symbols if this will create a win.
  • The Wild symbol substitutes for all other symbols.
  • Multiple low win symbols can be turned into Wild symbols at the same time, provided that each of the symbols can create wins if converted into Wilds.
  • The payouts of winning combinations featuring 2 or more WILD symbols will be doubled.

UFO Feature

  • The UFO may fly across the top of the reels during any spin.
  • If the UFO and the Cannon align above and below the same reel the UFO feature will be triggered.
  • When the feature is triggered, the triggering spin will end and any winnings will be awarded.
  • The reels will then immediately re-spin for free.
  • During this re-spin, Wild symbols will be distributed in random positions on the reels.
  • After all Wild symbols have been distributed the reels will stop spinning with the Wilds in place. All wins on the reels will then be awarded.

Return to Player

The theoretical percentage return to player (RTP) is 96.16%.
