The 1930s Detective Theme

Jack Hammer 2 commits to its pulp-comic premise. The reels are framed like comic panels, and the symbols come from the story: Jack Hammer, Lady Pearl, Don Crabby, and his hired goons sit at the top of the pay scale, while lower-value icons such as microphones, barrels of fish, and speedboats fill out the "Fishy Business" smuggling plot. The game was released in 2012.

How the Sticky Win Re-Spin Works

The core feature is NetEnt's Sticky Win mechanic. If the re-spin creates a new win, those symbols lock too and the reels spin again. The chain continues as long as each re-spin adds a fresh win, stopping only when one produces nothing new, at which point every locked combination is paid together.

Because the feature triggers on ordinary wins rather than a rare bonus symbol, it fires often and shapes the base game's rhythm. A single win can roll into a short streak of locked-in re-spins, which keeps a low-volatility slot engaging between bigger moments.

Free Spins and Doubled Wins

The bonus round triggers when five or more free spin symbols land anywhere on the reels. Every bet-line win is then doubled, and the Sticky Win re-spin mechanic keeps running as in the base game. Additional wild symbols join the reels during free spins, increasing how often combinations form and lock, and landing five or more free spin symbols again awards more spins. This mix of doubled wins, extra wilds, and chained re-spins is where the session's better payouts cluster.

RTP, Volatility and Max Win

At 97.07%, the RTP is among the stronger figures NetEnt has published, implying a lower long-run house edge than the typical online slot, though it remains a statistical average rather than a per-session promise. Paired with low volatility, the game pays small wins frequently and keeps a balance ticking over rather than swinging hard.

The trade-off is a modest ceiling: NetEnt lists the maximum win at 1980x your bet, sensible for a low-volatility title but well short of high-variance releases.

Betting and Controls

All 99 bet lines are permanently active, so you control cost through coin value and bet level rather than line count. Spin handles a single round, while Autoplay runs a set number of spins. It is worth opening the paytable first to read the symbol values and confirm the free spins trigger.

Playing the Demo on Slottomat

You can load the Jack Hammer 2 demo directly. The 5x3 grid scales cleanly to phones and tablets with readable controls. The demo is the easiest way to see how often the Sticky Win mechanic fires and how the doubled free spins behave before deciding whether this low-volatility, high-RTP profile suits you.

Similar NetEnt Slots to Try

If the detective theme and re-spin pacing land well, two other NetEnt titles are worth loading next. Cash Noire shares the noir-crime atmosphere and pairs it with a cluster-pays mystery mechanic. Serengeti Kings moves to a higher-variance profile but keeps a sticky-wild feature. For the studio's full range, browse the NetEnt slots library.

Common Questions About Jack Hammer 2

It's the full NetEnt game, including all 99 bet lines and the Sticky Win re-spin feature.

The published RTP for Jack Hammer 2 is 97.07%, which sits noticeably above the 96% figure commonly cited as the industry average for online slot games. In theoretical terms, a higher RTP represents a lower house edge over a large volume of spins - it's a long-run figure, not a per-session guarantee, but it's a meaningful data point when comparing games. For a full explanation of how RTP figures translate into actual session behavior, our RTP guide covers the mechanics in detail.
Jack Hammer 2 was developed by NetEnt (Net Entertainment), one of the most established studios in the slot development industry. NetEnt is also responsible for Starburst, Gonzo's Quest, and Dead or Alive a catalog that spans low-volatility casual titles through to some of the highest-variance games available. The full NetEnt slots library on Slottomat covers their complete output across different mechanic types and volatility tiers.

The published RTP, the sticky wild re-spin mechanic, and the full paytable structure are identical across mobile and desktop platforms the experience doesn't change based on which device you use to load it.
Jack Hammer 2 is a low-volatility slot, meaning wins land relatively frequently compared to medium or high-volatility titles. The practical trade-off is that individual win sizes tend to be smaller the low-volatility profile favors session consistency over rare but large payouts. Players who prefer extended sessions without long periods of no activity will find this profile comfortable. Our volatility guide covers the full spectrum and provides a framework for comparing how different tiers affect session behavior.
Jack Hammer 2 uses NetEnt's Sticky Win re-spin feature. When a spin produces a winning combination, the symbols forming that win lock in place and the remaining reels spin again for free. If a new win lands, those symbols lock too and the reels spin once more; the chain continues until a re-spin produces no new win, at which point all wins across the 99 bet lines are paid together. The mechanic runs in both the base game and the free spins round, where every bet-line win is also doubled.
Jack Hammer 2 occupies a specific niche in the NetEnt catalog: high published RTP, low volatility, and a single well-executed mechanic as the primary feature. It contrasts sharply with high-variance NetEnt titles like Dead or Alive 2, which trades the smooth session rhythm for a dramatically higher win ceiling. It's most comparable to Starburst in terms of volatility profile and mechanic simplicity, though the sticky wild re-spin system provides more layered tension than Starburst's expanding wilds. For players building a reference point across the catalog, loading Jack Hammer 2 and Gonzo's Quest back-to-back covers two fundamentally different design philosophies within the same studio.
Jack Hammer 2 is a practical choice for players new to mechanic-driven slot design because its core Sticky Win re-spin feature is visually clear and easy to follow when it triggers. The low volatility keeps the session from swinging dramatically, which makes the mechanic easier to observe over time, and the fixed 99 bet lines mean wins are evaluated automatically on every spin. Players who want to see the full range NetEnt produces could also load a cascading title and a high-variance one for contrast.
