Jack Hammer is a 5-reel, 3-row video slot from NetEnt with a comic-book detective theme, first released in 2010. It runs on 25 fixed paylines and is built almost entirely around one feature — Sticky Win — which locks winning symbols in place and re-spins the rest of the grid, letting a single spin snowball into a run of consecutive wins.

Sticky Win is triggered on every winning spin: any symbols that formed part of a payline win stay locked in place while the remaining positions re-spin for free. If the re-spin produces another win, those symbols also stick and the process repeats, so a lucky spin can chain through several consecutive wins before the reels finally come up empty. There’s no separate free spins round or multiplier trail — Jack Hammer’s entire pace and payout curve is built around how long a single Sticky Win chain can run, which keeps the low-to-medium volatility gameplay feeling more active than the stats alone suggest.
