Jack Hammer 4: Chasing the Dragon – Slot Overview
All the way back in 2011, NetEnt introduced players to Jack Hammer, a bold comic book-style slot that stood out with its innovative Sticky Wins mechanic. A sequel followed in 2013, but after that, the series went dark—until Jack Hammer made a surprise return over a decade later. Fast forward one more year, and the saga continues with Jack Hammer 4: Chasing the Dragon, bringing a fresh twist to the franchise with cluster pays and a hold ‘n’ spin-style bonus round—a first for the series.
This time, crime slinks through the streets of Chinatown, in a noir-soaked setting that NetEnt describes as an “Asian metropolis with a gritty edge.” The reels are framed by glowing lanterns and stylized calligraphy, evoking a moody, atmospheric backdrop that might remind players of San Francisco’s Chinatown—though the game stops short of naming it directly.
Despite the new setting, Jack Hammer 4 retains its iconic comic book aesthetic, with the hardboiled detective once again looking like he walked straight out of a Dick Tracy panel, trench coat and all.
Jack Hammer 4 – Game Grid & Payouts
Jack Hammer 4 unfolds on a 6×6 cluster pays grid, where players can place bets ranging from €0.20 to €40 per spin. The game offers three RTP models, with the top configuration delivering a return of 96.01%, paired with high volatility for those chasing big swings.
Wins are created by landing clusters of 6 or more matching symbols, either horizontally or vertically connected. The paytable includes:
-
Low symbols: Three stylized Chinese characters – Fortune, Dragon, and Peace
-
Mid symbols: A ceramic pot and a jade dragon statue
-
High symbols: Four character icons, including:
-
Pearl, the blonde femme fatale
-
A raven-haired mystery woman
-
The sinister elder Dragon
-
And, of course, Detective Jack Hammer himself
-
Payouts range from 0.3x to 1x the bet for 6-symbol clusters, while a full grid (36 OAK) pays between 7.5x and 40x the total stake, depending on the symbol.
Jack Hammer 4 – Features & Bonus Rounds
Jack Hammer 4: Chasing the Dragon brings back the iconic Sticky Wins mechanic and expands on it with wild modifiers, a hold ‘n’ win-style free spins round, and several feature buy options in the Elevate menu.
🔄 Sticky Wins
A signature feature of the series, Sticky Wins activate when a cluster win forms or when 3 or more scatters land.
-
Winning symbols are held in place while all others respin.
-
If the cluster grows, the new symbols are also locked and another respin occurs.
-
The process repeats until no improvements are made, at which point the win is paid.
🧨 Wild Features
The four corner positions on the 6×6 grid can contain only Question Symbols or Wilds, each with unique powers. Wilds substitute for all paying symbols.
Activated when part of a win, corner wilds can become:
-
Multiplier Wild – Adds a random multiplier (x2 to x10) to the win.
-
Upgrader Wild – Upgrades the entire cluster to a higher-paying symbol.
-
Cash Prize Wild – Instantly awards 0.5x to 2.5x the bet.
-
Expander Wild – Expands the cluster by adding up to 4 symbols.
🎲 Question Symbol
Transforms into one of several powerful super wilds:
-
x30 or x50 Multiplier Wild
-
Super Upgrader Wild – Transforms the cluster into the top-paying symbol.
-
Super Cash Wild – Awards 10x or 25x the bet.
-
Super Expander Wild – Adds up to 16 symbols to the triggering cluster.
🎰 Free Spins – Hold ‘n’ Win Style
Triggered by landing 5 scatters, players receive 3 free spins in a hold ‘n’ win format:
-
The grid starts with 3 sticky multiplier symbols (1x to 100x).
-
New multipliers reset the spin counter and stick in place.
-
Four corner modifiers are fixed throughout the round and activate when adjacent multipliers land.
🔧 Corner Free Spin Features:

-
Generate – Places 3 multipliers randomly or fills remaining positions (max 3 uses).
-

Jack Hammer 4: Chasing the Dragon – Verdict
While the leap from the original Jack Hammer to its first sequel was modest, Jack Hammer 3 took a sharp turn by introducing a scatter pays mechanic. Now, Jack Hammer 4 pivots again—ditching scatter pays in favor of cluster pays, a less trendy mechanic, but one that fits neatly into the slot’s puzzle-style gameplay.
The real connective tissue of the series, though, remains the Sticky Wins mechanic, and Jack Hammer 4 uses it well. Clusters trigger respins, locking in winning symbols and building upon them until no improvements occur—a system that feels as satisfying as ever. Adding corner-based special wilds that activate only when connected to a win is a clever touch, and their varying effects—upgrades, multipliers, cash prizes, and cluster expansion—bring a welcome strategic element.
As for the free spins hold ‘n’ win round, reactions may vary. It’s functional, layered with several modifiers, but lacks that eye-popping thrill. You’ve got multipliers, grid expansion, doubling features, and collectors—nothing wrong with it mechanically, but it doesn’t break new ground. That said, the 10,000x max win is a standout. It’s a major improvement over the underwhelming potential of Jack Hammer 3 and gives this entry a more rewarding edge.
In the end, Jack Hammer 4 feels like a step up—visually bolder, mechanically more ambitious, and with a prize cap that better matches its crime-fighting theme. It’s a solid sequel that maintains the series identity while experimenting just enough to feel fresh. Long-time fans should find plenty to enjoy in this noir-flavored outing.
