The Invisible Man online slot review
The Invisible Man draws on H.G. Wells’ classic 19th-century novella and also references the hit 1933 film. Its reels feature free spins and powerful Wilds, with possible outcomes that include multipliers and cash prizes.
Theme and story
Newcomers to The Invisible Man can watch the introductory video for some background on the story. In brief, the police are pursuing Griffin, a dangerous, deranged scientist who has developed a secret formula to make himself invisible.
Two distinct Wilds, Police and Griffin, are central to the game. They can unlock free spins and larger prizes, with further bonus rounds available during the main feature. Their movement keeps outcomes uncertain and provides much of the slot’s entertainment.
Graphics, sound and animation
Griffin’s secret laboratory sets a shadowy, mysterious scene. Bubbling formulas and potion bottles fill the background, while low-contrast symbols keep the screen subdued. When a prize lands, the symbols glow bright green, drawing attention to the winning payline.
The base-game music adds to the mystery and speeds up when a feature begins, building momentum. Animations throughout the features further contribute to an engaging playing experience.
Top Casinos to Play The Invisible Man:
How the Gameplay Works
The Invisible Man uses five reels and three rows, with 20 paylines for matching symbols inspired by the classic film and book. Low-value symbols are the standard card ranks from 10 to Ace. Higher-value symbols depict Mrs Hall, Mr Hall, Dr Cranley, Arthur Kemp, and Flora Cranley; Flora offers the biggest base-game prize at 500x your stake.
Police and Griffin work as a pair of Wilds: both substitute for every symbol during play and unlock free spins and later bonus games. Police Wild lands on the first reel, then moves one reel to the right after each re-spin, disappearing past the far-right reel. Griffin Wild follows the same pattern from the fifth reel, travelling left. Together, they can create larger payline combinations.
When the Police and Griffin Wilds move towards each other and merge, they award 10 extra spins. Finding the merging Wilds again can add another four spins.
Bonuses and free spins
Two meters above the reels track the Police and Griffin Wilds collected during free spins. Filling either 8-space meter triggers that Wild’s special round: Police Spins Bonus or Griffins Rage Bonus.
Police Spins Bonus features random burning Wilds that remain active for each of the three free spins. Griffins Rage Bonus takes you to three separate locations for a “pick and win” feature with cash prizes and multipliers of up to 4x. The game’s largest listed prizes are here: 188x your stake in the Griffin bonus and 1,000x your stake in the Police bonus.
Bet size, RTP and variance
The Invisible Man accepts total bets of $/€0.20 to $/€100 per spin. Its stated RTP is 96.30%, and its variance is medium to high. RTP is a theoretical long-run return, not a prediction of an individual result. Standard payouts may occur, while bonus rounds activate from time to time for players pursuing the game’s top prize.
Final thoughts
Overall, The Invisible Man is a detailed movie-themed slot with several bonus rounds supporting its reel play. Its features and animations add variety to the base game, while the listed top prize of 1,000x your stake may interest players considering NetEnt’s title.
