Infective Wild (Pragmatic Play) – Review & Demo Play

Introducing Infective Wild Slot Machine

I went into Infective Wild expecting a seasonal fling and found a 5x5, 40 payline bruiser with proper teeth. It’s a Halloween setup with a pumpkin-headed host, but the real pull is the spreading wild trick that turns cats and ravens wild on contact. Stakes run from £0.40 to £240, volatility is high, and the default RTP sits at 96.09% (96.06% via the buy). Free spins come with sticky wilds, and the win cap is 5,000x, which keeps the bonus sharp and the sweat real.

Theme & Design: Eternal Halloween Ambiance in Infective Wild

A foggy graveyard, twisted trees, bats, and glowing skulls frame the reels, with a jack-o’-lantern figure fidgeting beside them. The art is clean, animations slick, and the soundtrack leans on strings and a moody piano that ramps when wins land. It’s familiar Halloween fare, yet the presentation carries a nice punch. Visual clarity helps read the grid fast, which matters when wilds start spreading across cats and ravens. The whole scene feels tight and ready for repeat spins.

Symbols & Payouts in Infective Wild

The paytable covers 11 regulars. Lows are 10–A, paying 4x to 6x for five of a kind. Premiums climb through potion 12x, tombstone 16x, cauldron 20x, hat 30x, raven 40x, and cat 60x for five. Everything can land stacked, which matters when the infective effect chains across larger groups. Lines pay left to right, and hits need three or more matching on adjacent reels from the first.

The pumpkin wild substitutes and can deliver 60x for a five-line on its own. The scatter drops on reels 1, 3, and 5 to trigger the bonus. Key detail for feature play: cats and ravens are the ones that turn wild when touched horizontally or vertically by a wild. That conversion can ripple through connected symbols of the same type, creating sudden full-line payouts when stacks line up.

How to Play Infective Wild Slot

Set your stake between £0.40 and £240, then spin or use autoplay for a set run. Wins land on 40 fixed lines with three-plus matches from the leftmost reel. Quick spin and turbo are on tap if you prefer pace. The paytable sits behind the i button and explains the conversion chains. In the base, I focus on reel clusters where cats or ravens sit near potential wild positions, since one pumpkin can flip a dead spin into a tidy line-up.

Bonus Features in Infective Wild

Infective Wild is the headline act. When a wild lands and touches a cat or raven horizontally or vertically, those symbols become wild. If the newly converted symbols connect to more of the same type, the spread continues along that chain. This can tidy up scattered reels into clean lines in a blink. It’s a simple rule with nasty upside when stacks are in view.

Free spins trigger with three scatters on reels 1, 3, and 5. Before the round, a grid of eight cells spins and reveals 1, 2, or 3 per cell, totalling 8–24 spins. During the bonus, any wild on reels 1–4 sticks until the end. Sticky wilds are infective, so adjacent cats and ravens still flip wild, though those conversions don’t stick. No retriggers, so the opening layout and early stickies matter.

There’s a buy option for 100x the stake that drops you straight into free spins at a slightly lower RTP of 96.06%. Availability can vary by region. I use it when the base turns flat, as sticky starters on reels 2–3 can carry a round, especially with stacked premiums in view. It’s swingy, but that’s the point here.

Max Win, RTP, & Variance in Infective Wild

The max win is 5,000x. Default RTP is 96.09%, with alternative settings at 95.06% and 94.02% depending on venue. Variance is high, so the game will throw blanks and then fire when the grid lines up. The published hit rate is about 25%, and free spins average around once in 225 spins. That profile fits the sticky wild plan: streaks when placements fall your way, droughts when they don’t.

The 40p minimum may feel punchy if you usually grind lower stakes, but the range to £240 suits varied bankrolls. I size for bonus shots and let the infective chains do the work, rather than forcing speed. This maths needs patience, since sticky setups in the bonus drive the top-end returns. If RTP ranges are in play, I check the info panel before starting.

Infective Wild Slot Online - Our Verdict

Infective Wild is all about repeat wins once stickies land and start flipping cats and ravens. When positions fall early, the round can snowball and feel electric; when they don’t, it bites. I’m fine with that trade, since the rules are clear and the 5x5 grid gives the spread room to work. No multipliers means the cap stops at 5,000x, but the ride there is honest. I’ll keep it in my Halloween rotation and beyond.
