Jack Hammer 2: Fishy Business is NetEnt’s 2012 sequel to the original Jack Hammer, keeping the comic-book detective and swapping the villain’s lair for an underwater crime scene. It expands the format from 25 fixed paylines to 99 win lines and carries over the Sticky Win mechanic that made the original a slow-burning favorite.

Jack Hammer 2 runs the same Sticky Win mechanic as the original: any symbols forming part of a winning combination lock in place while the rest of the grid re-spins for free, and the chain can continue as long as new wins keep appearing. The difference is scale — with 99 win lines instead of 25, a single Sticky Win chain has far more paylines to connect through, which is part of why the sequel’s RTP (97.07%) and max win (800× bet) both edge out the original. The underwater “Fishy Business” theme adds new high-paying symbols but doesn’t change the core formula.
Pros
- 99 win lines give Sticky Win chains more paths to connect
- Slightly higher RTP (97.07%) than the original Jack Hammer
- Low-medium volatility with frequent chained wins
- Familiar Sticky Win mechanic for returning fans
Cons
- No dedicated free spins round or multiplier trail
- 800× max win is still modest by current standards
- Same core mechanic as the original — limited novelty for series fans
