Alien Invaders by Pragmatic Play - Slot Overview

Alien Invaders is a futuristic, high-volatility slot developed by Pragmatic Play and released on July 10, 2025. The game features a 5x5 reel grid with a bottom-row activation mechanic instead of traditional paylines. Winning combinations occur when three matching symbols land on the highlighted bottom row. This triggers the tumble feature, where winning symbols are removed, and new ones fall into place, potentially creating additional wins.

The base game starts with a win multiplier of x1, which increases by +1 for every 10 symbols removed through tumbles or scatter explosions. Special symbols include scatter symbols and wild multipliers, which apply once they reach the bottom row. The Free Spins feature starts with 7 spins and includes persistent multipliers and reel expansion, while the Super Free Spins mode starts with a x50 multiplier for even greater win potential.

Alien Invaders Design, RTP, and Volatility

The slot design embraces a classic 1950s-style alien invasion narrative, with sharp visuals and an eerie outer-space soundtrack. The reels float in space above a glowing city skyline, with robotic sounds and neon animations that amplify the extraterrestrial atmosphere.

The RTP is 96.50%, which is slightly above average. Alien Invaders is classified as a high-volatility game, meaning payouts can be infrequent but potentially large, especially during the Free Spins and Super Free Spins rounds.

Special Features of Alien Invaders

Alien Invaders offers a set of well-integrated bonus features that break away from standard slot mechanics. The focus is on symbol collection, multiplier buildup, and escalating rewards, especially during the bonus rounds.

Players can also activate the ante bet, increasing the stake by 25% to double the chance of triggering free spins. This feature, along with the win multiplier feature and dynamic reel expansions, adds depth to the gameplay.

Alien Invaders Symbols Explained

In Alien Invaders, the reels are filled with a collection of sci-fi-themed symbols, each styled to fit the game's futuristic alien invasion concept. The highest-paying symbol is the flaming alien leader. Other alien characters offer mid-to-high payouts. Lower-paying symbols include a set of futuristic gadgets: a glowing capsule, a control panel, and an alien scanner. All symbols pay only when three or more matching ones land specifically on the bottom row, which then collects any identical symbols stacked above for payout.
