Infectious 5 xWays (Nolimit City) RTP review: 96.02% (configurable)
The Infectious spread, from 1,024 ways to 110,592
The mechanic on the box is the reason to be here. Ordinary xWays symbols expand into stacks of a revealed pick; Infectious xWays go further, spreading their transformation to neighbouring positions so a single seed can convert swathes of the board. On a base grid of 1,024 ways, a well-placed infection chain can balloon the count to 110,592 — a two-orders-of-magnitude explosion in live ways, mid-spin. The game's superhero-horror framing (five afflicted “heroes”, each tied to game features) feeds four distinct bonus modes, and the escalation logic is consistent: the more infectious activity in the trigger, the deeper the mode. The 55,555x cap officially lands about once in 28 million spins, a disclosed rarity worth internalising before chasing it.
The mathematics of an outbreak
A 31.34% hit frequency keeps the base game visibly alive — infections fizzle more often than they cascade, but they fizzle entertainingly. The certified story is short by studio standards: a 96.02% default, one 94.27% rung below it, and the standout figure at the top — Infectious Spins: Mayhem Mode, the premium bonus, carries a database-sourced effective return around 96.81%, which puts the bought route (outside Great Britain, per the blanket ban) among the best formal deals Nolimit offers anywhere. Volatility is Very High (5/5) despite the friendly hit rate, because ways-explosion games pay their debts in rare avalanches, not steady instalments.

Verdict: the best host for the virus
Skip if: a documented 1-in-28-million cap chance reads as discouragement rather than transparency
Infectious 5 xWays takes one strong idea and gives it room: watching an infection chain convert a 1,024-way board into six figures of ways is a spectacle no other mechanic in the catalogue matches, and the four-mode bonus structure keeps the spread meaningful rather than cosmetic. The commercial layer is simpler than most stablemates — two builds to distinguish, one clearly-superior premium mode where buying is lawful. It remains a 5/5 machine whose cap is a statistical event, and it says so out loud; that honesty, plus the Mayhem math, is why it rates as one of the smarter picks in this weight class.
