Sci-Fi Invasion Slots

Created by the inimitable and highly talented team at OpenBet, Sci-Fi Invasion is yet another jewel in the crown of a company that has been producing consistently excellent video slots and standard slots games for a very long time now.

As is standard for the company, the game is leased out to individual real money online casinos and games room platforms and not actually hosted by the OpenBet brand itself. As a direct result of this, the house edge information cannot be sourced from the game’s developers directly but is accessible via each of the casinos and houses that stock the slot.

With this out in the open, let’s get down to dispelling some of the more important info, shall we?

Invasion of Opportunity

Set upon the all too familiar (and incessantly exciting!) theme of an invasion from another world, the Sci-Fi Invasion slot is sure to tick all of the boxes for any lovers of just about any work of fiction that follows this trajectory out there. Whether novels, comic books or movies about this kind of business float your boat, this slot is a must try if you’re into a little bit of competitive wager gaming on the side!

Traverse through the excitement and utter chaos of an otherworldly invasion as you work to defend the planet from those pesky little green men. Packing a standard 5 reels with a not so standard 9 active paylines, there is plenty about this game that works to create a unique feel and playing experience, aside from all of the intergalactic acquaintances you’ll make!

Intergalactic Bonuses and Extras

The game carries itself very well and packs a standard wild which can be utilised to bring into effect an entire range of additional avenues for winning. Perhaps the most notable of these is the one and only bonus round features within the game.

Now, usually when a game possesses just one bonus round, it is immediately marked as being less desirable than its peers. There’s usually nothing to back up this logic other than the view that the more bonus rounds that are available, the more opportunity there is within the game for a nice big juicy win. It’s hard to argue with this school of thinking, especially when the singular round available within the game is typically uninspired and unworthy of praising on account of its bespoke or unique nature.

In this instance, it pains me to inform you that whilst entertaining, the bonus round up for grabs within Sci-Fi Invasion is far from ground breaking in nature. Accessible once a player has received 3 or more of the bonus symbols on their reels, a new screen is presented which shows a solar system orbiting a sun. From here, the player must select which of the planets they would then like to invade with their very own intergalactic force. With the completion of each successful invasion, the player will be afforded the opportunity to choose another planet to try their luck with and is awarded a prize for each territory successfully taken. If unsuccessful at any point, however, the bonus round ends and its back to the trenches.

Standard Practice

The overriding motif taken from even the briefest spell within this game is that it offers relatively little in the way of fresh energy or concept. Though this doesn't necessarily mean to say that it’s not worthwhile, the more seasoned gamers out there; or for that matter those players who like to push the boundaries where possible, may find little joy in going through the motions here.

Going back to our aforementioned point, however, Sci-Fi Invasion is most definitely worth the time of anyone who enjoys the odd shootout with alien species!
