SG Digital is known for their high-quality games, following their own Open Gaming™ standard. The latter is well-trusted and forms a portfolio of over 3,000 games. Their take on this classic theme is, unsurprisingly, just as great. We loved testing it out, particularly as it’s quite innovative when it comes to how it implements the Megaways™ mechanic. The 1,000,000 maximum ways to win certainly doesn’t hurt, either! Read on to find out more.

Invaders Megaways™ Design & Gameplay

Fans of classic sci-fi movies will definitely want to take note of this video slot, as Invaders Megaways™ is UFO-themed.

Visual and Sound Design

SG Digital’s designers said they drew inspiration from classic sci-fi movies from the 50s all the way to the 70s. We think they definitely favoured the earlier aesthetic a little more though, and we’re glad they did! This super iconic style is highly reminiscent of movies such as The Thing from Another World and The Day the Earth Stood Still. Only in this case, it’s not just in black-and-white like in those classics, but in colour too!

The backdrop for the game is a night-time scene showing a house in the fields and some crop circles from above, bringing to mind Spielberg’s Close Encounters.

The soundtrack’s a real treat too. You’ll hear an incredibly catchy funk-and-dance inspired theme song playing throughout. (Admittedly, we did head-bang to this one quite a bit while writing this review). While playing, you’ll have sound effects for all the actions happening on screen. Most of these imitate some form of the stereotypical laser blast sounds we’ve come to associate with classic sci-fi. As expected, everything is well-mixed with no obvious seams. Top marks for sound design!

Playing Invaders Megaways™ – Symbols and Payouts

Front and centre you’ll see a 6-reel rectangular playing space, with a smaller 11-symbol reel above. These 11 symbols are all the play symbols for the game. You’ll find a 9 to Ace stack and a couple of higher-paying special symbols, which include a ray gun, a mid-abduction cow, a green alien, crazy scientist, and the invaders logo. Check out the paytable below – keep in mind that it’s for a bet amount of 1 coin.

When it comes to Wild Symbols, this game does things a little differently (we’ll cover this in a little more detail later). Essentially though, between reels 2 and 5, any symbol can become a Wild. These symbols will then substitute for any other symbol in the game – pretty handy for completing those winning combos! The specific symbol itself changes for every round.

Bonus Spin symbols are represented by a red Mars-like planet with the word ‘Bonus’ over it. We’ll cover how the Bonus Free Spins feature works further down.

Invaders Megaways™ Features

We’ve given you a mere glimpse of some of the innovative features above, but this is the section where we get into detail! Invaders Megaways™ keeps some classic Megaways™ features, and we’re glad it does. Apart from these though, it does introduce some others that aren’t so common. Innovation is almost always a good thing! We’re happy to see SG Digital thinking outside the box.

Cascading Reels

Cascading reels is one of those classic Megaways™ features that we mentioned earlier. With every winning combination of symbols, these will burst and allow the symbols above them to take their place. This introduces new potential winning combinations and will keep occurring until no winning combos are created.

UFO Wild Selector

Remember that 11-symbol reel above the main game? This is where that comes into play. With each spin, an animated flying saucer randomly selects one of the symbols. Once chosen, these symbols now become the Wild symbol for that spin. Only the symbols in reels 2, 3, 4 & 5 will get switched into Wilds though, so keep that in mind.

We really like this mechanic and think it’s quite an innovative way to introduce an additional element into the game. It keeps players on their toes, as even once the reels stop spinning, whichever Wild gets selected might completely change the outcome of that spin.

The Mythical Unicow

This feature’s quite a rarity! While you’re playing the base game, during any given spin, an animated flying-saucer-riding unicorn-horned cow might appear beside your reels: the Mythical Unicow! If this shows up, you’re in for a ride. The Unicow will zap the reels with its flying-saucer-mounted laser beam, causing them to show between 7 and 10 symbols each. At the lower end, this means 117,649 ways to win. This is the mythical number associated with most other Megaways™ slots’ maximum ways. Not here though – at the upper end of this feature, with 10 symbols for each of the 6 reels, it means you’ll have 1,000,000 ways to win!

Free Spins

This is where that Martian planet symbol from earlier takes effect. Depending on the number of these symbols that land on your reels, you might enter the bonus free spins round. The minimum number of Bonus Symbols needed to enter is 4. Once you’re actually inside the free spins feature, however, landing 3 more symbols will be enough to get you more free spins!

  • 4 Bonus Symbols – 7 Free Spins
  • 5 Bonus Symbols – 10 Free Spins
  • 6+ Bonus Symbols – 15 Free Spins
  • 3 Bonus Symbols within the Free Spins Bonus game – 4 Free Spins (retrigger)

Free Spins Multipliers

During the free spins, the flying saucer from earlier will keep selecting symbols from the top reel. This time though, it’ll only be from the higher-paying ones. Apart from that, all the selectable symbols will now perform a special function, each one of which is specific to the symbol. Check out the full list of special multipliers:

If selected:

  • Invader Logo – This will expand over all of the rest of the symbols of its reel, and will act as a Wild for the number of symbols present before.
  • Crazy Scientist – All the scientist symbols on the reels become Wild Symbols and add a 2× multiplier, which doubles with every cascade up to a maximum of 256×.
  • Green Alien – Each alien symbol will increase the number of symbols on its own reel and the adjacent reels up to a maximum of 10 symbols!
  • Abducted Cow – Each cow symbol becomes a 2× wild. When part of a winning combination, it will be considered as 2 symbols.
  • Ray Gun – A Wild symbol will be randomly added to the reels for each ray gun symbol. If a ray gun symbol gets added after a cascade, this will not cause the effect.

Invaders Megaways™ RTP, Max Win, Volatility


The Invaders Megaways™ Volatility is high. This means that, generally speaking, wins are quite few and far between. When you do land a winning combo, though, this’ll usually net you quite an impressive sum! That’s the nature of high-volatility games. Throughout the game you might encounter quite a few losses disguised as wins too. A lot of the lower-paying symbols don’t even cover the bet amount, even though you might win combos with them. Nevertheless, Invaders Megaways™’s high volatility makes it a thrill to play!


The theoretical RTP for Invaders Megaways™ is 96.30%. This is ever so slightly higher than competing titles. Hey, we can’t complain! It’s nice to have a decent RTP too, along with all those great winning ways and features!

Max Win

This is quite impressive too! The Invaders Megaways™ max win is 250,000 coins. We think you’ll agree that’ll make any player very, very happy! This amount makes sense considering the volatility of the game. It might be tough to reach anywhere close to here, but the few that manage will definitely feel out of this world!

Minimum and Maximum Bets

You’ll find a decent range of bets here. The minimum bet is set at 0.25 coins, while the Invaders Megaways™ max bet is set at 10 coins. While this isn’t an astronomically high amount, we do think it should be enough for most of you out there!

You can, of course, expect full mobile compatibility with this game. Graphics remain smooth without experiencing any lags. Whether you’re on a desktop, laptop, tablet, or smartphone, anywhere can be mission control for Invaders Megaways™.

How to Play Invaders Megaways™

Assuming you’re generally familiar with how Megaways™ slots work, things are very straightforward here too. While we’re sure you’ll find no problems with the interface, let’s go through it and explain what each button does.

Starting on the left-hand side, you’ll find a gear icon which will expand once you click it. This will allow you access to all the settings for the game.

The volume icon will mute the game’s soundtrack and sound effects. Right below it, with the hand symbol, you can switch the side at which these controls appear. Again, below that, you’ll find the question mark icon, which will lead you to the paytables and game rules.

On the other side of the screen, you’ll find your bet selector up top. Below that is an autoplay feature. Helpfully, this includes loss and win limiters, so you can fine tune it to your liking. Just below is the all-important green spin button, which is the icon you’ll likely be clicking the most!

Invaders Megaways™ Pros & Cons


  • Innovative game features
  • 1,000,000 ways to win
