Cosmic Invaders is a slot game inspired by the famous video games of the 80s and in particular by the popular game "Space Invaders", among the first that could be found in game rooms and bars. Obviously the graphics are much better due to the improvements brought on by Microgaming and the theme of the game, styled after an extraterrestrial invasion of our planet, is very reminiscent of the legendary game. The Cosmic Invaders slot machine has 5 reels and a maximum of 30 lines of betting that can be activated for each spin and has, in addition to the regular thematic symbols (spaceship, planets, etc.), 3 different special symbols: Wild, Scatter and Bonus, each tied to a particular feature with a funny animation. The Wild symbols, aside from the fact that they act as a wildcard by replacing all regular symbols, are also responsible for the Wild Invaders function: randomly, at the end of a spin, a flying saucer can pass over one of the rollers 2, 3 and 4, transforming the symbols into Wilds. The Scatter symbols, in addition to paying regardless of their position on the reels, can trigger the Free Spins mode, which can get to reward the player with a maximum of 8 free spins. Furthermore, during the free spins, one of the three center reels will become fully wild and the other two special features can still be triggered during this mode. The Bonus symbol finally activates the Alien Picking Bonus: when two Bonus symbols will come out simultaneously on reels 1 and 5, the player will have the opportunity to choose one of five aliens on the screen and receive the hidden award from it that can be a sum of money or the ability to choose a new alien, until there aren’t any left and all the prizes have been claimed.
