Interstellar Attack Review

Raise your hand if you loved retro shoot ‘em up games as a kid. Hits such as Space Invaders were pretty fun when we were kids, and they still have merit today. High 5 Games had that nostalgia in mind when creating the Interstellar Attack slot, which feels more like a Space Invaders clone than a slot game.

Recently, High 5 Games has been among the most innovative studios on the market. If you needed more proof of its capabilities, the Interstellar Attack online slot would provide it. A 25-payline slot with unique gameplay and 6 reels, Interstellar Attack is a retro shoot ‘em up-slot hybrid that will certainly tug your nostalgia strings.

Available for free and real money in any High 5 Games casino, Interstellar Attack is a slot, retro gamers should absolutely play.

Interstellar Attack Slot Setup and Paytable

The Interstellar Attack slot game is unique from any angle you look at it. For example, it has 6 reels, but if you count vertically, not horizontally as per the usual. Those are set in a pixelated galaxy, with both the setting and symbols as retro as they can be.

In terms of symbols, you get all kinds of space rocks and shooters as well as unique high-tech Modifiers. There are no classic sets of low and high-paying symbols. Instead, some of the space rocks have a value attached to them and shooting them scores a win.

You’ll get the highest payouts when you fill the red metre to the right, which adds Modifiers to the grid. These are not temporary – they will stay on the grid until destroyed. These include Multipliers and other boosters that can spice up your wins pretty nicely.

Interstellar Attack Slot Mobile Availability

The Interstellar Attack slot is developed on the HTML5 platform, which means it’s available on Android and iOS devices. You can play it on the go easily, thanks to the simple and effective layout and design.

How to Play the Interstellar Attack Slot Game?

To start this pixelated retro adventure, you’ll need to place a bet first. Your options go between €0.20 and €40 per spin. The higher your bet, the higher the Multipliers in play. Max your bet out, and you’ll benefit from great Multipliers that can spice your spins up.

While it looks like a retro arcade game more than a slot, the mechanics are deeply rooted in slot games. You spin the reels by hitting the big button on the right. The sixth reel from below will then spin to reveal the different space crafts that shoot the rocks on the screen. There are various types – some shoot only once, others shoot 3-4 beams that can destroy several rock symbols. The most powerful are the white/red ones that shoot a blast that clears a reel in full, which can be handy if there are Modifiers on the reel.

The base game action mostly revolves around the two metres that flank the reels. On the left, you have a green metre that fills whenever a double rock symbol is destroyed. The red one on the right fills in the same way. Once full, the green metre will permanently update your fleet. There are 4 space crafts in it – the ones that shoot only one beam are most common, while those that clear full reels are less common. If you’re lucky, the green metre will add another one of the less common spacecraft in your fleet, increasing your chances at clearing reels easily and delivering better rewards.

When the red metre is full, it will add a unique Modifier to the grid. It can be a Multiplier or another kind of Modifier that aims to improve your wins.

Interstellar Attack Slot Free Spins

The Interstellar Attack doesn’t use Scatters to trigger the Free Spins Round. Instead, you need to shoot at the alien spacecraft that hovers above the reels and moves one position to the right with each spin.

This spacecraft can appear randomly on the first reel. You then have 5 chances to hit it until it drops off the reels. If you hit it, you get 10 free spins. They are played on a special set of reels with special rules with Multipliers up to x6 in play. Shots fired by some of your spacecraft will award additional free games, so with a bit of luck, you can end up with dozens of extra free spins.
