The Invisible Man™ Slot Review – Free Play by NetEnt

The Invisible Man™ Slot Facts

The Invisible Man slot from NetEnt pays up to 500 times the stake at a 96.3% RTP, a 5-reel, 3-row game with 20 paylines built around the 1933 Invisible Man film and H.G. Wells’ original novel.

Police Wild and Griffin Wild drive nearly everything here, merging in the base game to open Free Spins and unlocking two very different bonus rounds along the way. Medium volatility keeps this one feeling steady rather than swingy.

The Invisible Man Theme & Design

NetEnt builds this one directly around the 1933 Invisible Man film and H.G. Wells’ original novel, with a logo that pairs a policeman alongside the bandaged, barely-visible figure of Griffin himself. Character symbols pull from the source material too, including Arthur Kemp, Flora Cranley, Mrs Hall, and the Doctor alongside the standard card values. Police Wild and Griffin Wild carry most of the visual identity, moving across the reels as walking symbols rather than sitting still, which fits a story built around a character nobody can quite pin down. The overall tone leans into mystery and detective-story atmosphere rather than horror, matching a game whose bonus rounds are framed as a chase between the policeman and the man he’s hunting.

How The Invisible Man Plays

Two Wild symbols anchor nearly every outcome: one begins on the leftmost column and creeps rightward with each respin, while the other starts on the rightmost column and drifts the opposite way. Whenever those paths intersect, the pair locks together on the spot, and once the resulting line pays settle, Free Spins kicks off with 10 rounds, adding 4 more for every extra pairing struck in that spin. Once the bonus starts, both Wild types roam freely across the whole grid rather than crawling in from the edges, and every departure from the reels ticks forward one of two dedicated trackers sitting above the action. Fill either tracker before the round wraps up and its linked bonus unlocks: one leads to three quick spins stacked with five randomly scattered Wilds apiece, the other opens Griffin’s Rage, a three-stage pick game built around banking coin prizes and stretching a multiplier as high as x4. A third Wild variety, exclusive to the five-Wild spins, behaves like any regular one once it appears.

RTP, Volatility & Win Potential

A 96.3% RTP sits a bit above the industry average of around 96%, and Medium volatility keeps that return arriving in a fairly even spread rather than long dry runs. A 29% hit frequency means a win lands close to three times in every ten spins, which is a comfortable pace that matches the Medium label well. The 500x maximum payout is modest next to today’s higher-variance releases, which fits a 2014 NetEnt title built more around steady, walking-Wild mechanics and bonus variety than a single oversized ceiling.

Our Verdict on The Invisible Man

This The Invisible Man slot review suits players who want a Medium volatility session with regular action and two distinct bonus rounds to look forward to, rather than a hunt for a massive multiplier. The walking Police Wild and Griffin Wild genuinely change how often merges and Free Spins occur, and Griffin’s Rage adds a nice change of pace from spinning reels. The tradeoff is a 500x max win that will feel dated next to newer, higher-ceiling slots. The free demo on this page is an easy way to see if the mystery-themed mechanics still hold up.

The Invisible Man™ Bonus Features & How They Work

Police Wild, Griffin Wild & Burning Wild

Whether spinning the base reels, in Free Spins, or during the five-Wild bonus, every Wild here substitutes for other symbols and counts toward whichever combination pays best. One Wild begins on the leftmost column and creeps a column over each respin, while the other begins on the rightmost column and creeps the opposite way. Whenever their paths cross, the pair locks together, and Free Spins kick off once resulting payline wins settle. A third Wild variety only shows up during the five-Wild bonus, working like a standard Wild there.

Free Spins

The pairing of the two moving Wilds during a base game spin switches this round on with 10 spins, and each additional pairing struck in that same spin tacks on 4 more. Once underway, both Wild types can land anywhere across the grid rather than only entering from the sides, and every exit from the reels advances one of two dedicated trackers above the action, each holding 8 slots. Filling a tracker before the round ends unlocks its matching bonus game, which plays out once the round finishes.

Police Spins bonus feature

Once its dedicated tracker fills up while Free Spins are active, a short bonus round of 3 spins kicks in. Each of those spins scatters 5 Wilds across freshly randomized positions on the grid, layered onto an otherwise Wild-free set of reels, so every spin guarantees a fresh cluster of 5 Wilds to build a win around.

Griffin's Rage Bonus Game

Completing this feature’s tracker during Free Spins opens a pick-and-reveal round across 3 locations, each with 5 hidden items. Every location hides 3 coin prizes, a multiplier boost, and a closing item that advances to the next stage. Coin picks add to a running total, letting the player pick again from what remains, while the multiplier item raises a starting value of 1 by one step, capped at 4. The final multiplier applies to the total once collected, and picking the closing item during the third location ends the bonus.
