Alien Invaders Review
Embark on an intergalactic quest in Alien Invaders.On every spin, 3-5 symbols can land on each of the five reels. When at least three matching symbols land on the bottom row, those reels become active, and all matching symbols on those reels form a winning combination and explode.If a scatter symbol reaches the bottom row, it explodes alongside symbols immediately adjacent to it horizontally, vertically, and diagonally. Wild symbols on reel three pay out when they hit the bottom row and can carry a multiplier up to 25x.Every spin in the base game starts with a 1x win multiplier which increases by +1x for every 10 symbols that explode during the spin. Any multipliers carried by wilds is also added to the total if they reach the bottom row.Landing 3 scatters awards 7 free spins, with an extra 3 spins for each additional scatter. During the bonus game, win multipliers persist between spins and wilds can carry up to 100x multipliers.What to expect: Land three matching symbols in the bottom row to activate those reels and form a winning combination Every 10 symbols that hit increases a win multiplier by +1x for that spin 3+ scatter symbols trigger the bonus game where the win multiplier remains in between spins
