Our take
Yggdrasil's arcade-style slot features expanding wilds, bidirectional paylines, and 96.30% RTP across a 5-reel, 3-row grid.
Cyrus the Virus is a colourful arcade video slot from Yggdrasil Gaming that eschews traditional left-to-right paylines in favour of a bidirectional model—five lines pay left-to-right, five pay right-to-left, and the middle reel stops last for added tension. This design creates an unusual cadence that some players find refreshing.
The slot's theme is bacteria and viruses rendered in a cartoonish, almost comical style rather than grotesque. Bright greens and exaggerated animations dominate, and the soundtrack emphasises important events: wins, near-misses, expanding wild triggers, and re-spins. The game uses stacked symbols, which allow full-reel fills to land and create cascading wins.
The key feature is the expanding wild on the middle reel, which triggers a re-spin when it lands. Given the middle reel stops last, landing the expanding wild mid-spin creates genuine excitement, though the mechanic remains relatively simple. The 96.30% RTP is solid, and high volatility pairs well with the 2000× max-win cap, positioning this as a game for players with steady nerve.
Pros
- Bidirectional paylines (left and right) create gameplay variety
- Middle-reel-stops-last mechanic adds suspense to each spin
- Expanding wild re-spin feature triggers frequently enough to remain engaging
- 96.30% RTP is competitive in the high-volatility category
Cons
- Theme may feel dated compared to modern slot aesthetics
- Max win of 2000× is conservative for modern high-volatility slots
- Bidirectional paylines can confuse new players unfamiliar with the mechanic
- Limited feature depth beyond expanding wild re-spins

FAQ
- How do the bidirectional paylines work?
- Five paylines pay from left to right, five pay right to left, so wins can form in either direction.
- Why does the middle reel stop last?
- The delayed middle-reel stop is designed to build tension, often creating near-miss animations or last-second wins.
- Does the expanding wild re-spin guarantee a win?
- No; the re-spin is a free additional spin, but wins depend on symbol alignment as usual.
