Alien Invaders Demo Review

Today, we’re strapping in for a journey with Pragmatic Play, a developer that rarely shies away from a classic theme. This time, they’re dusting off the old sci-fi tropes of ray guns, little green men, and flying saucers in their release, Alien Invaders. The alien invasion theme is as old as the arcade itself, so the challenge is immense: deliver something fresh or get lost in a black hole of clichés. Let’s see if this mission is a success.

Theme and Design

From the moment Alien Invaders loads, it beams you up with a delightful dose of retro charm. This isn’t a dark, gritty sci-fi epic; it’s a playful, cartoonish adventure that feels ripped straight from a 1950s comic book. The game is set against the purple void of space, with planets and stars dotting the background. A friendly-looking UFO hovers to the left of the grid, hinting at the features to come.

The 5×4 reel set is populated by a cast of colourful characters. The high-paying symbols include a heroic female astronaut, a classic green Martian, and a couple of other quirky alien creatures. The low-paying symbols are a ray gun and a rocket ship, followed by the usual card royals. Everything is rendered in a bright, bubbly art style that is immensely likable. The sound design is the perfect complement, with a theremin-heavy, spooky-yet-funky soundtrack that perfectly captures the retro B-movie vibe. In my view, the presentation is a home run; it’s fun, vibrant, and doesn’t take itself too seriously.

Gameplay and Features

This is where the mission gets truly interesting. Alien Invaders is a highly volatile slot with 40 fixed paylines, which means it’s designed for players chasing those big, screen-clearing wins. The RTP is a healthy 96.55%, which is a great number for a game with this much going on. The gameplay is a fantastic blend of two distinct and powerful bonus features.

Let’s walk through the command console.

The Free Spins Feature: This is your more traditional bonus, triggered by landing 3, 4, or 5 of the “Alien Invaders” Scatter symbols. Doing so not only awards an instant prize of 2x, 10x, or 100x your stake, but also grants you 10, 20, or a massive 50 free spins, respectively. During the entire free spins round, the middle three reels (2, 3, and 4) are loaded with stacked Wild symbols (the UFO), dramatically increasing the potential for multi-line wins. This feature can also be retriggered, making it a very solid and straightforward bonus round.

The Alien Invaders Respins Feature: This is the heart of the game and where the biggest prizes are hiding. This feature is a unique twist on the popular “Hold & Win” mechanic and is triggered by landing 6 or more Money symbols anywhere on the grid.

When this happens, you are taken to a new screen where only Money symbols and blanks can land. You start with 3 respins, and every time a new Money symbol hits, the respin counter resets to 3. The triggering symbols stick in place, as do any new ones.

Here’s the brilliant part: as you collect Money symbols, you move them towards the UFO on the left. This UFO can unlock a variety of rewards:

• Direct Cash Prizes: Ranging from 10x to 250x your bet.
• Multipliers: A multiplier from 2x to 50x that will be applied to the Money symbols collected under that UFO at the end.
• Free Spins: A prize of 10 to 100 free spins, which will play out after the respins feature concludes.
• Jackpots: One of four fixed jackpots: Mini (20x), Minor (50x), Major (250x), and the Grand Jackpot of 2,500x your bet.

The maximum win for the entire game is capped at 2,650x, making that Grand Jackpot the primary target.

Final Thoughts

So, is Alien Invaders a successful expedition? Absolutely. Pragmatic Play has delivered a game that is bursting with character and backed by some truly engaging mechanics. By offering two distinct paths to big wins—the stacked wilds of the free spins and the jackpot hunt of the respins—they ensure the gameplay rarely feels one-note.

This slot is perfect for the player who loves feature-rich games and the thrill of the “Hold & Win” mechanic. If you enjoy chasing fixed jackpots and don’t mind the high variance, you will have a blast with Alien Invaders. Players who prefer a steadier, less volatile experience might want to look elsewhere.

When I look for comparisons, the quirky alien theme immediately brings Play’n GO’s iconic Reactoonz to mind, but the gameplay here is far more traditional. The core Alien Invaders Respins feature puts it in the same category as the Money Train series from Relax Gaming, but I feel the addition of the varied UFO prizes gives Alien Invaders its own unique and compelling identity.

In conclusion, Alien Invaders is a wonderfully fun and feature-packed slot that successfully breathes new life into a classic theme. It’s a mission I can highly recommend you accept.
