Cyrus the Virus Slot Review

Cyrus the Virus is a video slot from Yggdrasil Gaming with 5 reels and 5 paylines that pay both ways, giving you essentially 10 paylines. One of Yggdrasil’s earlier slots, Cyrus the Virus was released in May 2015 and can be played at online casinos such as YoYo, Shadowbet or PlayOjo.

Theme and basic information

The theme of this slot is not the only thing unusual about it, but that shouldn’t surprise us with a game from Yggdrasil Gaming. They like to create something unique and they don’t mind being quirky once in a while. Cyrus the Virus fits in quite well here. The theme is germs, bacteria, viruses – microscopic organisms that tend to make us sick. The background could potentially be the interior of a cell and we get a somewhat sickly green colour as well.

The micro-organisms show up in various colours and they get mean faces once they become a part of a winning combination. The meanest of them, a dark blue one with loads of tentacles, is worth 2,000 coins in a 5-of-a-kind combination. All the others follow far behind worth between 100 and 400 coins in such a winning combination.

Another cute feature are the little worm-like thingies that poke their heads from the holes on each side, waiting for a winning combination to show up. Imagine them acting as antibodies who destroy the evil organisms when they form a winning combination.

Basic gameplay

Cyrus the Virus is one of the simplest video slots around, not just in Yggdrasil’s portfolio but anywhere else as well. You only get 5 paylines that pays both ways, for winning combinations from left to right and right to left.

The reels stop from the outside to the middle, first reels 1 and 5, then 2 and 4, and finally reel 5 stops, determining whether you get any wins or not.

You can bet between €0.10 and €40 on this slot, making it a decent medium range option. And the auto-play feature comes in particularly handy, because nothing much is happening whilst we wait for the middle reel to bring us the only feature this game has.

Bonus feature

The name-giving Cyrus the virus in this slot appears on the middle reel only and he is one mean fella. He acts as the wild symbol and expands on the whole reel to form winning combinations with symbols from both directions. He then locks into place and we get one free re-spin, hopefully giving us another win (or the first win).

Once winning combinations have been paid out, the whole thing begins anew. You keep the reels spinning, waiting for Cyrus to show up on the middle reel.

That doesn’t happen very often, but it can be incredibly worthwhile when it does happen. A little luck is certainly handy as well, but Cyrus has brought us over 100x our bet on rare occasions.

Conclusion: A quirky slot that will keep you entertained for a while

The theoretical RTP (Return to Player) for Cyrus the Virus is 96.3%, which is good value and slightly above average. Cyrus the Virus is certainly a volatile slot. Wins are rare, big wins even rarer. Indeed, when we played this game, we were able to keep playing because of a few big wins here and there.

But that was absolutely enough. The slot is cute and quirky and manages to entertain even when no winning combinations form. You just keep watching the reels spinning and wait for Cyrus to appear or any other winning combinations for that matter.

And if you’re lucky, a few big wins are enough for you to walk away a winner. This slot can keep you hooked because of its simplicity. But the volatility might drain your budget. We recommend you walk away whilst you’re up. That’s what we did when we played 200 spins and won a total of 370x our bet in the end.
