Bonus 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 and 10 symbols. (Between 117,649 and 1,000,000 ways).



This feature is triggered by landing 4+ Bonus symbols and retriggered by 3+ Bonus symbols. The number of spins awarded is as follows.

3 Bonus symbols awards 4 spins (retrigger only).

4 Bonus symbols awards 7 spins.

5 Bonus symbols awards 10 spins.

6+ Bonus symbols awards 15 spins.

During the free spins a random picture 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:

All Logo symbols expand to fill the reel. The expanded symbol acts as multiple smaller symbols (defined by its number) when calculating winning ways.

All Scientist symbols become Wild and until the end of the spin, the win multiplier doubles every cascade (starting at 2 and capped at 256).

Each Alien symbol increases reel height for its reel and each adjacent reel increasing the number of ways (up to 1,000,000 ways).

All Cow symbols become 2x Wild. Each 2x Wild is considered 2 Wild symbols for the purpose of calculating winning ways.

1 Wild is added randomly to the reels for each Ray Gun symbol. Ray Gun symbols which cascade into view do not cause more wilds to be added.

Free Spins are played automatically. Free Spins are played with the same total bet, awards and winning combinations as the spin which triggered the feature. Free Spins will end when there are no Free Spins remaining. Free Spins will end if the maximum win has been achieved.
