Cyrus the Virus

This unusually themed online video slot from the Scandinavian sensations Yggdrasil is set inside one of the body's cells and sees a number of invading virus cells battling it out to make you sick. Don't worry though it isn't all bad news, with a top jackpot of a massive 2000x your original wager and an RTP of 96.30% you are sure to pick up some nice wins as you try and defend yourselves from these bacterial invaders. 

More about the Software Provider

Yggdrasil is an internationally acclaimed software developer who has won numerous industry awards from Best Slot Provider at the B2B Awards in 2017 to Innovator of the Year at The International Gaming Awards. They are responsible for games such as Vikings go to Hell and Reptoids and are famous for their stunning graphics and high-definition aminations. 

Appearance and Sound Effects

The reels are placed inside a cell which has an aqua green glow and is perforated with small holes at the sides. There are seven different symbols, some of them looking particularly nasty and could easily be the common cold virus or something much more sinister. You will also see a deep purple one which has tentacles which is the highest paying symbol offering 2000x your wager should you land five of them in a winning combination. Information about the symbol's multipliers is available in the paytable, and this will help you get familiar with the game's rules.

Accompanying this quirky release is a rather fitting soundtrack that complements it well, but if you prefer to play without sound, it can be easily turned off.    

Bonuses and Special Features

The games Wild symbol is a bright purple virus with some bold black eyebrows. It will substitute for all of the symbols on the reels and will only even land in the middle. When it does, it will expand the entire reel and activate a respin, giving you the chance to boost your win. Bets start from as little as £0.10 per spin ut if you fancy betting big then you can wager up to £40.


This game has a fairly standard 5x3 reel formation with a total of 10 paylines. Information about the winning combinations can be found in the paytable at the bottom of the screen.

Mobile Compatibility

Unfortunately, Yggdrasil has not yet made this game compatible with mobile and tablet devices, and so those who enjoy playing on the go may feel slightly restricted. However, we think that the game looks great on a bigger screen and will suit those who enjoy playing at home on the desktop.

Our Verdict

We really enjoyed this game, and despite some features making us feel a little queasy such as when the blue worm-like creatures come out of the sides of the cells and dart across the screen, it was a lot of fun. Slots that are different really stand out against their competitors and with a user-friendly layout and easy to grasp rules we think that Cyrus the Virus is a real winner – just remember to disinfect your screen after playing.
