The signs of superheroes are wild, and the signs of the earth are scattered. Wild replaces all symbols except the Earth symbol and pays the highest bonus. The scatter symbol triggers a free spin bonus when it appears three times anywhere on the reels. Players can play up to 12 free games with four unique features - each based on each superhero character.
When Mr. Fantastic appears and covers the entire third reel, the player will receive 4 additional free spins, in which Mr. Fantastic's role plays an ever-expanding wild state and provides players with a better chance of winning.
