How I tested Invaders Megaways

I love all things science fiction, so based on the theme I was looking forward to testing this slot game from WMS. In order to establish that you can trust my review, here are some of the criteria and considerations:

  1. I played the slot. It is pretty easy to find reviews online from people who do not have the experience of playing the game, but not here.
  2. One of the first things I look at is the RTP and the volatility of a game I am about to review. These statistics give you an insight into what the size and frequency of your wins will be.
  3. The graphics and the design are a top concern for me. I want a slot I play to burst off the screen and really keep me engaged.
  4. I take into account the size of the maximum and minimum bets. They should cater for small budgets and for high rollers to maximize the audience.
  5. Understanding the symbols beforehand can be crucial to the enjoyment of a game. You could pick them up as you play, but if you read this review we will give you a breakdown of the symbols.

Paytable 1
Paytable 2

Minimum & Maximum Bet

The range on the limit for bets is from $0.10 to $10. This is great for people with a small budget however people who prefer higher stakes may want to look elsewhere.

Autoplay option

There is an autoplay option with customizable settings allowing between 5 and 100 auto-spins and to stop them when you lose or win over a certain amount.


96.3% is a nice RTP it is right in the middle of the average range for online slot machines. 


This high volatility means wins are not regular but when they come — they come high.

Maximum win

You can win up to 25,000x your stake in a single win. That’s a very impressive maximum win.

Invaders Megaways has a low minimum bet, but be careful of that high volatility

The range on the limit of bets is on the lower end, but that may be because of this game’s higher volatility. Overall the technical data is very promising for this game, so let’s take a look at the features and the design to see where how well this game has been served.

Game Features

Special Symbols, Free Spins and other features

UFO Wild Selector

This was one of the first things I noticed on the game grid, so let’s start here. Above the reels, you will see a row displaying all the symbols of the game, as you spin the UFO placed above it will move side to side on this bar. It will then fire its tractor beam at that symbol and any instances of that symbol on the reels will become wild and any cascades which occur after the win too.


Cascading Reels

This works similarly to cluster pay slots. Any symbols which are involved with a win are zapped off the grid and new symbols drop in to replace them. Dropping symbols can form a win and if this happens the cascades will continue until no more wins are generated and you can spin again.

Unicow Feature

You’ve heard of a unicorn right? Well, this is the same as that except it’s a cow with a single swirly horn extruding from its head. During any random spin, a unicow can come flying onto the screen in a small spacecraft. The spacecraft has a ray gun attachment that can blast a reel and randomly change the amount of symbols on it. The increase in symbols in a reel is how we build-up to the 1,000,000 paylines. The amount of paylines is displayed in the top right.

Free Spins

Look out for the red planet scatter symbols as landing four to six of these makes you take off to another planet as you enter the free spins feature. The amount of free spins you play with depends on the amount of scatter symbols. Four symbols equal seven free spins, five symbols give you 10 free spins, and six give you 15. You will notice the row of symbols gets smaller and only displays the five higher value symbols, because now for each individual free spin one of those high-value symbols is chosen to be wild. Each of these wilds come with a special modifier:

  • If the invaders symbol is chosen then any occurrences of it will expand to fill the whole reel and be included in winning combinations.
  • If it is the mad scientist then a multiplier applied to winnings is increased for every cascade, starting at two and going as far as 256 times.
  • When the alien throwing up a peace sign is chosen, any reels with an alien symbol receives an increase in the amount of symbols it holds.
  • Every wild cow symbol will start too count as two wild symbols.
  • And finally the ray gun – this introduces one wild into any reel in lands in.

More free spins can be earned during free spins mode. Landing three scatters will add four more free spins and landing four scatters retriggers the entire round again.

Free Spins

Invaders Megaways has some fun features plus symbols come with modifiers in the free spins feature

These are not the usual features you might find in a Megways slot game, but they are a lot of fun, are in keeping with the theme, and bring the potential for bigger wins. I am a huge fan of the UFO wild selector which brings a wild symbol to almost every spin, and if you’re fortunate enough to find the unicow then you could be well on the way to 1,000,000 paylines.

Invaders Megaways is a feast for the eyes and the ears.

I like the background on this one. It places the player on a UFO gliding around Earth; making crop circles, observing and seeking someone to “beam up”. I love the music in this one too. As soon as the game starts this low pulsating beat is introduced which slowly builds up into a fantastic, yet slightly uncanny soundtrack. The symbols are perfect and have been drawn with engagement in mind. The abducted cow symbol is not just a cow but is a cow clearly in distress that is being raised from the ground by a beam. Even the numbers aren’t just numbers. They’ve been designed to look a little bit more ‘spacey’, reminiscent of the unintelligible font used in sci-fi classics like The X-Files and the Alien franchise. People who have played Invaders From The Planet Moolah will notice a lot of familiar areas in this game. However, this game has been so well designed that it is clear WMS hasn’t just put the word Megaways on the end but has actually put some work into adapting it.

Solutions if you have some issues with a game

If the game is interrupted during a cascade, the previous bet will be designated as void and your stake is returned.


I get the feeling playing this game that a lot of love has been put into it. There are so many Megaways games out there that are just the same as the old version but with the name put at the end. This is certainly not the case here. This game has been well designed and filled with well-thought-out features which play out well on screen. This is a strong recommendation from me.
