Slot Details

Invaders Megaways is a cascading video slot with six dynamic reels, featuring in the base game 2 to 7 symbols per reel to create a random number of 64 to 117,649 ways to win in every round. During the Unicow modifier and in the Free Spins, up to 10 symbols can appear on each reel, leading up to a maximum of 1,000,000 ways. Pays are awarded for three to six matching symbols landing on adjacent reels from left to right only. You can battle the alien invaders on desktop, mobile and tablet from 0.25 to 10 credits per spin. The game has medium to high volatility with an RTP of 96.30%.

A dreamy farm scene on a starlit night is opening up when you load the game with wide cornfields and the farmhouse in the background. Crop signs indicate that the alien invaders have already landed, ready to set off the mayhem on the dynamic reels that take up most of the screen. As expected, the main audio are UFO and ray gun sounds that will accompany the wild transformations and symbols removals after winning cascades.

The pay symbols start at the low end with card royals from 9 through to A, awarding 0.20x to 0.28x your bet for a single six of a kind. They are followed by ray guns, flying cows, aliens, the wacky scientist and the slot logo. Six across the reels will yield 0.80x to 4x your stake. There is no wild symbol as such but any pay symbol can be randomly chosen to transform into a wild for the current game round. Lastly, a red planet marked with ‘Bonus’ acts as the scatter.

Invaders Megaways Slot Features

After releasing Spartacus Megaways in September 2020, SG Digital went quiet on new releases, only to make a comeback with a trio of new creations – Perfect Potions Megaways for April 2021, Invaders Megaways for June 2021 and Jin Ji Bao Xi Megaways for July 2021. While we already reviewed and played the first one, let’s take a closer look at what the sci-fi themed Megaways has in store.

Unchanged is the Megaways engine with cascading symbols and reactive wins, which will randomly select the total number of bet ways for every spin sequence. In the base game, 2 to 7 symbols can land on each reel, virtually creating unlimited variations of rows and ways anywhere from 64 to 117,649.

Hitting one or more winning combinations will trigger the reactive win feature where all symbols from the combo/s will be zapped from the reels while the remainder drops towards the bottom before new symbols tumble into the empty spaces. Hit another winner and the process is repeated, ad infinitum so to speak, until no more wins occur.

Invaders Megaways Random Wild

SG Digital is introducing a new modifier to the base game and Free Spins called UFO Wild Selector, although it works slightly different in the bonus round. A horizontal display is placed on top of the main reel set, containing all regular pay symbols. At the start of every spin, the UFO will hover over the display and randomly select one pay symbol. All occurrences of the chosen symbol appearing in the marked area between reel two and five at any time during the same spin sequence will then turn wild, providing more opportunities to score a win. In our example above, the cow was selected.

Watch out for a second UFO with a cow pilot to appear at any time in the base game, triggering the Mythical Unicow modifier. The cow will point its ray gun to the reels, causing them to expand and show 7 to 10 symbols per reel, thus creating anything from 168,070 to 1,000,000 bet ways for the current spin. Due to the high win potential, the feature triggers very rarely.

Invaders Megaways Free Spins

Having four, five or six and more scatters in view by the time a game round concludes, will trigger 7, 10 and 15 Free Spins respectively. Hitting three to six scatters on a free spin will retrigger 4 to 15 spins. Throughout the bonus round, all reels can show 2 to 10 symbols with the number of bet ways ranging from 64 to 1,000,000.

Before the start of the feature, the horizontal display will shorten, showing only the five premiums. The UFO Wild Selector will again select one at beginning of every free spin, turning all occurrences appearing on any reel into wilds, each with a different modifier.

  • Ray Gun: Additionally to ray guns turning wild, one random wild is added to the reels for every ray gun in view on the initial cascade. Any following winning cascades will have no further random wilds added.
  • Flying Cow: All cows appearing on any reel throughout the spin sequence will turn into x2 Wilds. More than one in a combo are multiplied by each other.
  • Green Alien: Additionally to aliens turning wild, they will increase the height of their reel and both adjacent reels. The expansions stay active until the current free spin concludes. The maximum number of betways is 1,000,000.
  • Whacky Scientist: Additionally to scientists turning wild, the win multiplier starts at x2 and doubles after every winning cascade within the same free spin, up to x256. It will reset at the end of a spin sequence.
  • Invaders Logo: Additionally to logos turning wild, they will expand to full reel height and award a wild multiplier equal to the number of symbols on the respective reel. More than one in a combo are multiplied by each other.

Final Verdict

With Invaders Megaways, SG Digital is showing that there is still life left in the immensely popular game engine. Not only life but also room to create new modifiers. Well, maybe not totally new, but a novel way how they are triggered and applied in a spin sequence. Add to that the comical touch of the sci-fi theme and you got a highly playable slot with mega win potential.
