UFO sightings, or reports of extraterrestrials, are not as rare as we might think, and they are often documented even though not many believe most of the time. However, aliens seem to have a unique obsession with cattle, as cows are most often subjected to abductions. The same appears to be the case in this Invaders Megaways slot, where aliens have landed on a farm in the middle of nowhere. In addition to the fantastic visuals, the game can also deliver up to 25,000x the stake. Read on for the details!

About Invaders Megaways Slot

The Megaways engine is known for providing unpredictable grids and many possibilities. The same is true in the Invaders Megaways slot, where six reels are included. Each can hold up to 7 symbols per spin, making things very diverse - it certainly did during my gameplay. Payouts require matching symbols to land on three or more successive reels, starting from the one on the far left.

This exciting way of playing was slightly undermined by the betting options. The betting range is not particularly inclusive to high rollers, as the possibilities span between £0.10 and £10 per spin.

Design, Symbols and Graphics

Among the first things that impressed me about the Invaders Megaways slot are the vibrant colours, perfectly conveyed theme and superior graphics. The game is set on a farm, with a house on the left and crop circles on the right. The starry sky dominates the top of the screen, and there are many amazing animations too.

The low-value symbols occupy the first half of the payable and are depicted as 9-A royals in different colours. Following behind them are the high-value symbols - ray guns, flying cows, aliens, a scientist and the game's logo, which can pay up to 4x the stake for a full payline.

Regarding special symbols, the red planet is the scatter that can trigger the Free Spins feature. On the other hand, any of the regular pay symbols can turn into a wild, but more about that later.

RTP, Variance and Payouts for Invaders Megaways Slot

The Invaders Megaways RTP is 96.30%, which is a good value, slightly above the industry average. Moreover, the hit frequency rate is 33.48%.

During my gameplay, wins were not very frequent, but they did deliver some fantastic prizes, thanks to the high volatility. This model is paired with a fitting maximum win potential of up to 25,000x the stake, which may lead to some incredible outcomes.

Gameplay and Features on Invaders Megaways Slot

While playing the Invaders Megaways slot, I came across some incredible bonus features that made my experience more entertaining and dynamic. Let's look at what they are and how they work.

Cascading Reels Feature

This feature is often combined with the Megaways engine and can create an even more unpredictable way of playing. Namely, winning symbols will be removed from the grid, and the empty positions will be filled with new ones. This resulted in some tremendous consecutive wins.

UFO Wild Selector Feature

The four middle reels of the Invaders Megaways slot are highlighted throughout the game, plus an extra row containing all pay symbols is presented on top of the grid. A UFO will select one of those symbols on each spin, and all instances of it in the highlighted area will be made wild.

Mythical Unicow Feature

This randomly triggered feature activated a couple of times during my time playing this game. Namely, the Unicow zaps the grid, potentially causing all reels to hold between seven and ten symbols. The best thing about this feature is that the number of paylines can reach up to 1,000,000.

Free Spins Feature

To activate this feature, 4, 5, or 6 scatters are required to land simultaneously, delivering 7, 12, or 15 free spins, respectively.​One of the high-paying symbols will be chosen as the wild for every spin, each having a modifier of its own. 

  • Game's Logo - all instances cover the respective reel and are counted as multiple smaller symbols in a winning combination;
  • Scientist - the win multiplier doubles on every cascade up to 256x;
  • Alien - increases the number of symbols on that reel and adjacent reels, providing up to 1 million Megaways;
  • Cow - turns all cow symbols into 2x wilds;
  • Ray Gun - adds 1 randomly placed wild ray gun symbol, but not if the ray gun lands from a cascade.

The Free Spins feature can be retriggered by landing 3 or 4 extra scatters during the bonus round, so theoretically, you may benefit from unlimited free spins.

SlotsWise Verdict

Overall, the Invaders Megaways slot is an incredible addition to the alien genre. The developers have done a masterful job with the design of the visuals and conveying the theme. I found the whole atmosphere very entertaining and immersive, plus the dynamic way of playing was a significant advantage. 

Combining the Megaways engine with cascades is always a great idea in slots, but the Invaders Megaways slot is also packed with many other features. All of them can potentially lead to some fantastic wins, but the small betting range is one of the biggest downsides of this game.
