There are 13 symbols in total, this includes 6 low-paying symbols. These are represented by 9, 10, J, Q, K, and A. There are also 5 premium symbols, these are represented by rayguns, cows, aliens, scientists, and an Invaders logo symbol. In addition to these regular symbols is a planet bonus scatter and a wild symbol. The highest paying symbol is the Invaders premium, which pays 4x for 6 across all reels. Wilds substitute for all symbols except the scatter symbol, apart from during the logo modifier where it can be replaced by the expanded symbol.

Invaders Megaways Features

During the base game, a random paying symbol will be selected by the UFO and all instances of that symbol in reels 2 to 5 will act as a wild symbol for the entire spin. During the ‘Mythical Unicow‘ feature and Free Spins, the UFO will convert all instances of a random paying symbol to a wild symbol on all reels.

On any base game spin there is a chance that the Unicow will appear causing all reels to show between 7 – 10 symbols.

Landing 4, 5, or 6 scatter symbols during a base game spin will trigger the Free Spins feature. Awarding 7, 10, and 15 Free Spins. Landing 3 or more scatter symbols during a Free Spin will award 4 additional spins. During Free Spins a random premium symbol will be selected to act as a wild symbol for the entire spin. Depending on the chosen wild one of the following modifiers play out;

Logo – All logo symbols expand to fill the reel.
Scientist – All scientist symbols become wild and until the end of the spin the win multiplier doubles for every cascade.
Alien – Each Alien symbol increases the reel height for its reel and each adjacent reel increasing the number of ways.
Cow – All cow symbols become 2x wild. Each 2x wild is considered 2 wild symbols.
Ray Gun – 1 wild is added randomly to the reel set for each ray gun symbol.


Overall, I think this slot is very well made by the provider and shows off fun visual aspects. With a max win capped at 25,000x and a big range of features on offer. Be sure to try out the game for yourself and check out our exclusive casino offers.
