Jack Hammer by NetEnt is a five-reel, three-row slot with 25 paylines and a comic-book theme built around the contest between Jack Hammer and Evil Dr Wuten. The game uses independently spinning symbols, creating 15 visible reel positions, with wins formed from matching symbols across paylines from left to right. The bet range runs from 0.25 to 250 per spin.
The main features are Wild symbols, Sticky Wins and a free spins round. Wilds substitute for other symbols on a payline, while Sticky Wins lock winning symbols in place and respin the remaining reels until no new win appears. Landing three or more scatter symbols can also activate this feature. A separate bonus game is triggered by five or more scatters, awarding 10 to 20 free spins depending on the number landed.
During the free spins bonus, all wins are multiplied by 3x. This page includes a demo version, so players can play for free and practice before playing for real money. Jack Hammer is designed for desktop and mobile play, with a structure centred on its paylines, scatters, Wilds and bonus rounds.
