Alien Invaders Demo Play for Free

Join an intergalactic journey in Alien Invaders. On every spin, 3-5 symbols can land on each of the five reels. When at least three matching symbols appear on the bottom row, those reels become active and all matching symbols form a winning combination before exploding. If a scatter symbol reaches the bottom row, it explodes alongside symbols adjacent to it in all four directions. Symbols on reel three pay out when they hit the bottom row, carrying multipliers up to 25x. Each spin starts with a base win multiplier of 1x, which increases by +1x for every 10 symbols that explode during the spin. Any additional multipliers carried by wilds are added to the total if they reach the bottom row. Landing three or more scatters awards 7 free spins, with an extra 3 spins awarded for each additional scatter. During the bonus game, win multipliers persist between spins and wilds can carry up to 100x multipliers. Key wins include:

– Activating reels by landing matching symbols on the bottom row
– Increasing a base win multiplier by +1x every 10 symbol explosions
– Triggering the bonus game with three or more scatters
