alien invaders
Game Description:
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.

Alien Invaders Slot
Yet another fun slot from Pragmatic Play, Alien Invaders, was released in 2025, adding another interesting slot to their expansive portfolio. The Alien Invaders slot game draws inspiration from other titles in the Space theme, with gameplay set in outer space. As with all Pragmatic Play UK online slots, Alien Invaders features innovative gameplay mechanics that elevate the overall experience.
Alien Invaders Game Background
The Alien Invaders slot takes place on a 5-reel playgrid, with 3, 4, or 5 symbols appearing on each reel on all spins. The varying number of symbols in this slot game resembles Megaways slots, with each spin unique and containing a different number of symbols. Matching combinations can land if 3 or more identical symbols appear on the bottom row, making the symbol of that kind active. The matched symbols on the bottom row become ‘active,’ and all instances of the symbol on the other reel positions will be involved in the matching combination.
In all releases in Pragmatic Play’s slot portfolio, detailed visuals that effectively showcase the game's theme are present, with Alien Invaders being no exception. The gameplay takes place on an unearthly planet with a backdrop featuring hundreds of stars and a rocky surface. Given the title Alien Invaders, it is no surprise that Pragmatic Play has incorporated an alien into the slot visuals, with an animated alien figure sitting on a UFO beside the playgrid.
Many slot games have been based on the space theme, including notable titles such as the Spaceman slot and Starburst Galaxy.
Alien Invaders Slot Symbols
All symbols in the Alien Invaders slot game feature alien elements, though some align more closely with the theme than others. The lower-value symbols are depicted in classic playing card imagery commonly found in live casino games, each with unique colours and eyes embedded, many resembling faces. The higher-value symbols showcase the space theme directly, with a range of animated characters resembling outer-world creatures being the icons.
Lower Value Symbols:
- 10
- J
- Q
- K
- A
Medium Value Symbols:
- Green Alien
- Light Blue Alien
Higher Value Symbols:
- Darker Blue Alien
- Fire Alien
The space theme is further showcased in the bonus symbols of the Alien Invaders slot game, with the Wild being represented by a purple alien and a fiery meteor for the Scatter.
Alien Invaders Bonus Features
Over the years, many UK online casino slots have introduced Wild symbols, which often serve the same primary function. During the base gameplay, the Wild symbol can land on the third reel, and if it reaches the bottom row, it may act as a substitute for base game symbols to create matching combinations. Additionally, the wild symbol can appear with a random multiplier ranging from 1x to 25x, which may be applied if it's part of a matching combination.
As with many Megaways slots, the Alien Invaders title features the Tumble game mechanic, which can be triggered after all matching symbol combinations. For each matching combination, the participating symbols will disappear from the reels, and the remaining symbols will fall to the bottom of the screen. Empty positions will be left in their positions, and new symbols will fall from above to fill the reels.
The Scatter symbol in the Alien Invaders can appear on all reels, and if it appears on the bottom row, it will explode, along with all other symbols adjacent to it.
The prize multiplier feature in the Alien Invaders slot always begins at 1x and increases by +1 for every 10 symbols that explode during tumbles, or by the Scatter explosion. Additionally, if multipliers land attached to Wild symbols, their values will be added to the total multiplier value if it reaches the bottom row.
In the Alien Invaders slot, if 3 or more Scatter symbols appear on the reels in the same spin, the Free Spins feature will be triggered. In this feature, 7 free spins will be awarded, plus an additional +3 for each Scatter symbol landed beyond the third to trigger the bonus. During this bonus feature, all increases of the prize multiplier achieved will persist throughout the bonus rounds. Additionally, if Scatter symbols reach the bottom row during the Free Spins feature, an additional free spin will be awarded. In the Free Spins feature of the Alien Invaders slot, the Wild symbol can appear on reels 2, 3, and 4, and can have a random multiplier value that ranges from 1x to 100x.
Alien Invaders Mobile Play
Like many modern and classic slot games, Alien Invaders uses HTML5, enhancing its accessibility. The software has become an essential in all online slots in the iGaming industry, enabling titles to be played on various devices, including smartphones and desktop PCs.
