Alien Invaders
Alien Invaders is an intergalactic-themed slot developed by Pragmatic Play, featuring five reels that can hold between three and five symbols each. The game employs a unique mechanic where matching symbols must reach the bottom row to activate the reels and trigger win explosions. Every 10 exploding symbols increase a win multiplier for the spin, while wilds on the third reel can apply up to a 25x boost. Landing three scatters launches a free spins bonus where the accumulated win multiplier persists between spins.
