Invaders Megaways slot Big Win June 2021

A flashy WMS release Invaders Megaways proves its worthiness by paying a tremendous prize of 9,965.64x the stake to a fortunate gambler. With a bet of €1 per spin, he triggered the Free Spins feature and in a while got away with a payout of nearly €10,000.


4 Bonus symbols landed and awarded 7 spins to start.


Thanks to the Alien modifier that enlargened the grid to a staggering 1 million ways and numerous cascades that lasted over 2 minutes a crazy win of €9761.36 was achieved on the second spin. On top of that, 13 more Scatters dropped and awarded 15 extra spins!


Then, only smaller wins followed, as well as there's been another feature retrigger hit. However, nothing decent was achieved and as the bonus ended, a total prize of €9,965.64 was paid to the slotter.

Invaders Megaways Review

Last Update: 16.06.2021. Author: SlotCatalog.

While it’s true - as announced by WMS - that you get a “feature on every spin” in Invaders Megaways, the base game is still a pretty monotone and slow-paced affair. The wild feature is the same all the time, no matter what symbol the UFO selects, and even the top game logo premium symbol pays no more than 4x for 6OAK. The ‘mythical’ Uni-Cow feature is almost as rare as the Loch Ness monster, but the bonus round makes this a worthwhile game to check out.

The reels are set above a farmland at dusk or dawn, as seen from a UFO’s perspective, complete with a crop circle on the right-hand side. Loosely based on the arcade classic, Space Invaders, you’ll see a small UFO hover above a symbol display reel on top of the megaways grid (more about this below). The retro/cosmic soundtrack fits the bill perfectly too, and fans of supernatural phenomena should feel right at home in this game.

Invaders Megaways Features

The Cascading Win system removes all winning symbols from the grid, and this makes room for new winning chances to drop down from above. This is a common feature in most Megaways slots, and it adds to the unpredictability of each spin. The Cascading process repeats as long as you keep winning.

All the pay symbols are on display in a special row above the reels, and a UFO goes back and forth before it settles down on a randomly chosen symbol per spin. All instances of the selected symbol turn wild for the specific round, but only within the green frame that surrounds reels 2 to 5.

The Uni-cow might appear in a UFO on any given base game spin, and it shoots a rainbow-colored beam that makes all reels display between 7 and 10 symbols. This means that you’ll be playing with between 168,070 and 1,000,000 win ways when this feature triggers.

You trigger the Bonus Round with 7, 10 or 15 free spins, respectively, whenever you land 4, 5 or 6 red planet scatters anywhere in sight. The backdrop shifts from earth to the weird alien planet depicted, and you win 4 to 15 extra spins whenever you land between 3 and 6 scatters in the bonus round.

Only the 5 premium symbols are on display above the reels in the free spins round, and the UFO picks one of them per spin. This awards 1 of 5 symbol-specific modifiers randomly per spin as follows:

  • The game logo - expands all logo instances to cover the full reel.
  • Scientist - the line win multiplier doubles on every cascade in a single sequence, starting at x2 and going up to a maximum of x256.
  • Alien - increases the reel height on all alien symbol reels, and adjacent reels, generating up to 1 million win ways in the process.
  • Cow - turn all cows into x2 wilds, and these count as 2 wild symbols in terms of win ways.
  • Ray gun - awards 1 wild randomly placed per ray gun symbol, but not if the ray gun lands from a cascade.

Review Summary

If there is one thing we are fussy about, it’s the game pace. It might seem like a minor detail, but it’s really not when you’re going to plough through hundreds, if not thousands, of spins in a single session. It’s way too slow and awkward in Invaders Megaways, but we know that not all players care too much about this. We like how WMS is not afraid of going their own way with this engine though, and they keep doing new stuff with it on every new release.

The low symbol value means that you’re pretty dependent on lengthy wild-induced cascades to keep yourself afloat in the base game. These come along once in a while, but as usual, the bonus round is your best bet for the big bucks. The Unicow is not called ‘mythical’ for no reason, as you’ll see that feature about as seldom as you would a real UFO. Random bonus round modifiers keep things varied, and if you can stomach the pace, this is a pretty decent release.


  • Randomly selected symbol turns wild
  • Unicow UFO awards up to 1m megaways
  • Bonus round w/ 1 of 5 modifiers per spin
  • Win up to £250,000


  • Awkward and slow gameplay pace

If you enjoy Invaders Megaways you should also try:

Rick and Morty Megaways - is a branded effort from Blueprint, and you’ll follow the eccentric, drunken scientist and his less-than-clever grandson on a space adventure with 4 unique bonus rounds. You’ll also benefit from mystery symbols in the base game, and you can win up to 50,000x your stake.

Visitors - is a cleverly done alien abduction slot from ELK. The ETs are “pranking” the locals, and you’ll get several UFO modifiers in the base game. The bonus round comes with multiplier frames that can double all the way up to x4,096. This can lead to payouts up to 10,000x your stake.

Astro Newts Megaways - is a cartoonish Iron Dog release, and it’s all about collecting fuel cells to travel to different planets in the solar system. You start out stuck in the Moon’s orbit, but you can go all the way to Uranus during the bonus round. Each tier/planet comes with unique modifiers, and you can win up to 20,000x your stake.
