Game overview
Jack Hammer is a slot game developed by NetEnt that incorporates a comic book detective theme, with symbols depicting the protagonist Jack Hammer, criminals, and thematic icons. The game uses a 5-reel, 3-row structure with 25 fixed paylines.
The base game operates with standard symbol combinations forming the core gameplay. Bonus features are triggered by landing three or more scatter symbols, activating the Free Spins feature.
During the Free Spins bonus, a sticky win re-spin mechanic is applied, where winning symbols remain in place while the other reels re-spin, allowing for additional winning combinations. This enhances potential payouts and introduces increased variability.
Jack Hammer is generally classified as a medium-to-high volatility slot. Base game outcomes occur with moderate frequency, while bonus rounds introduce higher variability and opportunities for larger rewards. These characteristics are governed by the game’s internal mathematical model.
From a technical perspective, Jack Hammer uses a random number generator (RNG) to ensure each spin and feature event is independent and operates according to fixed rules.
