50s UFO Themed Fun!

SG Digital is known for their high-quality games, following their own Open Gaming™ standard. This standard is well trusted and forms a portfolio of over 3,000 games from SG Digital. Their take on this classic theme is unsurprisingly just as great. We loved testing it out since 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 our interest either. Read on for the details!

Invaders Megaways™ Design & Gameplay

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

Visual and Sound Design

SG Digital’s designers said they drew inspiration from the sci-fi movies 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 reminded us 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. This really reminded us of Spielberg’s Close Encounters, maybe that’s where the 70s influence comes from!

The soundtrack’s a real treat too. You’ll find an incredibly catchy funk-and-dance inspired theme song playing throughout. Admittedly we did headbang 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 find 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. These 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 below. 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.

Invaders Megaways™ Symbols

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

You might have gotten a glimpse for some of the innovative features above, but this is the section where we get into detail! Invaders Megaways™ keeps some classic Megaways™, and we’re glad it does. Apart from them though, it does introduce some features 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

Invaders Megaways™ Cascading Reels

Cascading reels is one of those classic Megaways™ features that we talked about. 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

Invaders Megaways™ 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 on 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 can keep 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

Invaders Megaways™ 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 and cause 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

Invaders Megaways™ Free Spins

This is where that Martian planet symbol from earlier comes into play. 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 though, landing 3 more symbols will be enough to get you more free spins!

Free Spins Multipliers

Invaders Megaways™ 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 function is specific to the symbol. Check out the full list of special multipliers:

If selected:

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 thought you might win combos with them. Nevertheless, Invaders Megaways™’ 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 despite all those great winning ways and features!

Max Win

This is quite a treat too! The Invaders Megaways™ Max Win is 250,000 coins. We think you’ll agree that’ll make any punter 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!

Invaders Megaways™ Mobile Play

Invaders Megaways™ Mobile Play

You can of course expect full mobile compatibility with this game. Graphics remain smooth and there’s no lag to be seen either! 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




All in all, from our entire slots list, we’re quite certain you’ll enjoy your time playing with this slot. The soundtrack on its own is enough to have you jamming for a while, let alone all the features! So prepare your bets, set phasers to ‘stun’ and get ready for lift-off with Invaders Megaways™.
