Alien Invaders is a sci-fi cascade slot from Pragmatic Play with an unusual way of forming wins. A win only counts when matching symbols land in the bottom row first. Matching symbols on those active reels then join into a cluster and explode, and new symbols drop in to continue the chain.

A win multiplier starts low and climbs as more symbols explode during a cascade sequence. In the base game it resets with every new spin, while in the free spins it persists from one spin to the next. Wilds on the middle reel carry multipliers of their own, and scatters explode along with the symbols around them. Free spins are triggered by scatters.

It may suit players who enjoy reading a grid in a new way and like a multiplier that carries across a whole bonus. Some spins can show matching symbols without paying because of the bottom-row rule. The published RTP is 96.50%. The free demo uses play credits, and results are random.
