Alien Invaders Demo & Review

Alien Invaders review

Alien Invaders uses an unusual bottom-row mechanic. Each of the five reels shows three to five symbols per spin, and when at least three matching symbols land on the bottom row, those reels become active and every matching symbol on them explodes as a win.

Scatters that reach the bottom row explode along with the symbols around them. Wilds on reel three pay when they reach the bottom and can carry multipliers up to 25x. Every base-game spin starts with a 1x multiplier that increases by 1x for every 10 symbols exploded, and wild multipliers add to it. The in-game screens advertise up to 5,000x. The RTP is 96.5%. One of Pragmatic Play's more original recent designs.

Alien Invaders RTP, volatility and max win

RTP: the default return to player is 96.50%, meaning that over a very large number of spins the game is designed to pay back around 96.5 units for every 100 wagered. Some casinos may run a lower configuration; the info screen inside the game shows the exact figure. How RTP works.

Volatility: The provider hasn't published an official volatility rating for Alien Invaders, so we don't label it. Judge it from the demo: if wins are rare but bonus rounds carry most of the value, treat it as a higher-variance game and size your stake accordingly. Volatility explained.

Max win: the maximum payout is 5,000x the stake. What max win really means.
