Alien Invaders

What if we put the vile creatures aside for a moment? In the Alien Invaders slot, released in July 2025 by Pragmatic Play, we are taken to the complete opposite of this horrific spectrum. A place where the alien invaders are cute, smiling, and almost too adorable to be believable. How about playing alongside them in a friendly atmosphere reminiscent of Play N Go’s Reactoonz? You’ll have the opportunity to collect Wilds, multipliers, Free Spins with a new win mechanic, and many other fun things.

The Alien Invaders slot machine doesn’t seem to take place on Earth; the reels spin on an unknown planet surrounded by large canyons and rock formations strangely reminiscent of Martian soil. This cosmic setting will be our playground for meeting these strange creatures! First, let’s learn a little about the game’s stats: high volatility, an RTP of 96.50%, and a win potential of up to 5,000x your bet. As for the wager, it can be adjusted between $0.20 and $240 per spin. An Ante Bet can be activated to double your chances of accessing Free Spins for an additional 25% bet on each spin.

The game grid appears in the center of the screen with 5 vertical reels and 3, 4, or 5 random rows of symbols appearing with each spin. The bottom row is always marked. Wins occur when 3 or more matching symbols line up at the very bottom of the reels. When this happens, the reels containing winning symbols will become active, and all instances of that winning symbol will count toward winning combinations.

We find the little monsters from elsewhere as strong symbols. There are 4 of them and they can pay 0.25x, 0.50x, or 1x the bet for each symbol present in a winning combination. The A, K, Q, J, and 10 symbols can pay between 0.05x and 0.10x for each symbol in a winning combination.

Tumbles, Wilds, an explosive Scatter, win multipliers, Free Spins, and bonus purchase options will make your Alien Invaders journey even more exciting.

Tumble

The Tumble feature is activated after each winning spin, once winning combinations have been paid and all winning symbols have disappeared from the grid. The remaining symbols will tumble down the screen, and the vacated positions will be replaced by new symbols from above. The tumbles will continue until no more winning combinations appear following the tumbles. All wins will then be added to the player’s balance once the tumbles are complete.

Wilds

The terrifying octopus-like symbol is a Wild that can substitute for all symbols except the Scatter. It can appear on the third reel during the base game and on reels 2, 3, and 4 during Free Spins. The Wild is inactive and does not substitute unless it lands on the bottom row. Above it, it is marked as inactive and becomes active once it reaches the bottom row. The Wild can carry a random multiplier of 1x, 2x, 3x, 5x, 10x, or 25x.

Scatter

The meteorite is the Scatter symbol capable of appearing on all reels. When a Scatter appears or reaches the bottom row, it explodes along with all adjacent symbols horizontally, vertically, and diagonally. Exposed symbols are considered winning combinations.

Win Multiplier Feature

Each spin starts with a 1x multiplier. Every 10 symbols exposed during tumbles or thanks to the Scatter, the win multiplier will increase by +1x. The multiplier carried by the Wild is also added to the win multiplier when the Wild reaches the bottom row. The current win multiplier applies to winning combinations.

Alien Invaders vs. 4 different slots from Pragmatic Play

Free Spins

Land 3 or more Scatter symbols to trigger 7 Free Spins plus 3 additional symbols for each Scatter found beyond the third. The number of symbols landing on each reel during Free Spins will always start at 3 and after each spin, it may randomly increase by 1 on random reels, up to 5 per reel. These reels will then remain at this size until the end of the bonus.

All win multiplier increases obtained during Free Spins will persist until the end of the bonus.
Additionally, each Scatter landing on the bottom row will award an additional Free Spin. The Wild symbol during Free Spins can carry random multipliers up to 100x.

Buy Free Spins

You can opt for the bonus purchase option at any time for 65x the bet or 400x the bet to activate Super Free Spins with a starting multiplier of x50.

Ready for the alien invasion!

In the Alien Invaders slot, Pragmatic Play introduces us to aliens invading the reels with a smile. Multiplier Wilds, explosive Scatters, Free Spins, and buy options allow players to consolidate their winnings. Moreover, the system used to win prizes is quite new, working with cascading wins and based on matching symbols reaching the bottom row, thus unlocking interesting avalanches. While we doubt all of this will be enough to truly shake up the slot industry, we found the action quite entertaining overall.
