Intro: Game Theme

Part of the reason why space occupies the minds of so many people is the promise of the unknown. There are no guarantees what we might find above the clouds. Maybe we find a whole lot of nothing. Alternatively, we find a galaxy teeming with life waiting to welcome us! Until we know for certain, we will have to make due to with Alien Antix! This intergalactic journey has packed all the important things: cascading reels, Wilds with multipliers, colossal symbols and free spins!

While the graphics are good, they are not the most impressive we have seen from Blueprint Gaming slots. Parts of it do look incredible. We really enjoyed the smooth animation of the galaxy to the right of the reels slowly spinning. However, the rest of the background is much more limited. Despite that, we do like the art style the team has gone for. We see a variety of planets and moons, all floating above a massive world we see beneath the reels. The actual icons are designed to be friendly and goofy. If you want scary aliens, you are playing the wrong game.

How it Works

You play this release on an eight-reel board. There are no paylines in Alien Antix. Instead, payouts are granted using the cluster pays system. Here, we have a sixty-four symbols total on the playing field. In order to form a winning combination, we need at least five matching icons to appear in adjacent positions. The identical symbols have to touch horizontally or vertically to form a winning cluster. Through the control panel, we can spin the reels, set up Auto Play, change our total bet and look at the paytable. We can bet between £0.20 and £20 on each spin.

Icon designs are unique to this slot. There are no playing card royals in play, or any other generic symbol we are used to. No, all standard icons in this game are aliens! There are happy aliens, tired aliens, nervous aliens, cute aliens. If you can think of an alien type, they probably have it! Furthermore, all the different aliens come in different colours to make it easier to tell them apart. There are no Scatters. Instead, the only special symbol is the Wild, which is designed to resemble an atom.

Bonus Rounds

After each win, icons that were part of that winning combination are removed from the playing field. First, existing symbols will fall down to take up any empty spots. After that, brand new icons will fall from the top until the playing field is full of symbols again. This allows players to score several wins for the price of a single spin. It also plays quite well with cluster pays and can create incredible chain reactions! Especially when it is combined with the Wild.

See, Wilds in this Blueprint Gaming release come with win multipliers. When a Wild helps complete a win, it does not disappear. It moves by one position in a random direction, and its multiplier is increased by one. This continues as long as cascading reels keep producing more wins for the Wild to help complete. When the winning streak inevitably ends, the Wild will disappear from the playing field.

Furthermore, getting three Wilds on the playing field at the same time grants eight free spins. There are no sticky, multiplier Wilds for the duration of the free spins round. Instead, every spin will have a guaranteed Colossal icon! Colossal symbols can appear randomly during normal gameplay as well. If one is about to land, you will see the screen shaking before they appear on the reels. Any symbols that were in that position before are replaced, with the exception of Wild icons.

Last, but not least are the progressive jackpots! Currently, Alien Antix is exclusive to William Hill, where the Vegas Millions progressive jackpots can be found. The slot is hooked into that network, and can grant one of those five progressive jackpots on any spin. Which one will it be is determined at random! Unfortunately, we do not know if this is a timed exclusive or not. We are relatively certain that if this game launches outside of William Hill, the progressive jackpot will be removed.


We did enjoy the time we spent playing this release, though the exclusivity deal did leave a sour taste. We are not big fans of online casinos limiting where we can play our favourite titles. Still, if we disregarded that, Blueprint Gaming have done a phenomenal job with Alien Antix. This is an excellent cluster pay slot that will keep you spinning for hours on end!
