NetEnt’s top detective is back in action. This time, his investigation takes him to a nameless Chinese city, where a sinister secret remains hidden. With your help, our hero might just crack the case and discover the whereabouts of the dragon.
However, this is no easy investigation, and plenty of risk awaits you if you choose to tackle this problem. That’s why we’ve put together this article, exploring everything there is to know about Jack Hammer 4: Chasing the Dragon.
Jack Hammer 4: Chasing the Dragon Visuals & Sounds
The background image is on the simpler side, with most of the space being taken up by tall buildings and neon signs. Chinese lanterns and letters are prominently displayed everywhere, making it clear where the game is taking place. The lanterns and wires sway in the wind, which is a nice touch. Triggering the bonus feature also changes the backdrop, now showing the interior of the home where the dragon statue is kept.
Available icons include Chinese letters, women in traditional Asian dresses, an elderly man smoking a pipe, and our brave detective. The Jack Hammer 4: Chasing the Dragon slot also features the word Wild as Wild symbols and golden coins playing the role of Scatters. On top of that, you’ll find quite a few bonus icons tied to specific bonuses.
The latest release from NetEnt has a solid music track, although it tends to blend into the background compared to the sound effects. The team makes it clear whenever you’re close to activating a feature or have just scored a big win, which is a nice touch.
Jack Hammer 4: Chasing the Dragon Gameplay & Features
The game uses a 6×6 playing area with cluster pays instead of paylines. This makes it slightly simpler to form winning combinations, as the winning combinations don’t have to follow a set path. Instead, you’ll need six or more matching icons in adjacent positions to get a payout.

Sticky Win
Getting a winning cluster or at least three Scatters activates the Sticky Win feature. The triggering symbols lock in place while the rest of the reels spin. If the cluster grows or more Scatters land, you get more re-spins. Otherwise, the bonus ends.
Wild Features
The four corners of the reels can unleash additional features if the correct symbols appear. Each corner can display Question icons or corner Wilds. Both can transform into symbols with special effects, whose effects unlock when a cluster pay connects to one of these corner icons. Available bonuses include:
- Wild Multiplier transforms Wilds or Question icons into multiplier symbols. Wilds get up to a 10x multiplier, while Question icons can appear with a 30x or 50x multiplier.
- Wild Upgrader upgrades symbols to a higher tier. Wilds bump up icons to a higher-value symbol, while Question icons can become Super Upgraders, boosting to the top-tier symbol on the paytable.
- Wild Cash Prize awards random cash prizes. Wilds can grant payouts from 0.5x to 2.5x your bet. Meanwhile, Question icons can award 10x or 25x your stake.
- Wild Expander adds more Wilds to the grid. Wilds will add up to four extra Wilds to the cluster, while Question symbols will flood the reels with up to 16 new Wilds.
If multiple of these bonuses activate simultaneously, they will take effect following this sequence: Wild Expander, Wild Upgrader, Wild Multiplier, and Wild Cash Prize.
Free Spins
You’ll need at least five Scatters to win the Free Spins feature in the Jack Hammer 4 slot. This unlocks three free spins and places three multipliers on the reels. While the feature is active, only the multiplier icon can show up on the reels.
New corner bonuses are available during this feature and activate when multipliers land beside them.
- Unlock expands the grid up to two times. It adds a top row first and then a bottom row if you trigger it again.
- Generate drops three random multipliers and can trigger up to three times.
- Double lives up to its name, doubling the value of nearby multipliers. It can activate up to three times.
- Collect adds up all active multipliers and adds their sum to your total win.
If several corner features unlock at once, they’re awarded in the following order: Generate, Unlock, Double, and Collect.
Elevate
NetEnt’s release lets you spend money to make specific bonuses more likely or to trigger them outright. In Jack Hammer 4: Chasing the Dragon, you have the following options:
- Free Spins Hunt doubles your chance of triggering free spins and costs 2x your bet.
- Wild Activator guarantees at least one Wild feature and increases your odds of winning the Free Spins feature tenfold. It costs 10x your stake.
- The Free Spins option lets you buy free spins outright for 100x your wager.
- Lucky Draw activates either the regular or the Super Free Spins feature. This will add three or four Wild bonuses, followed by five Scatters that guarantee three no-cost rounds. It requires you to spend 150x your bet per spin.
- Super Free Spins guarantees the more valuable version of the feature for 300x your stake.
Jack Hammer 4: Chasing the Dragon RTP and Payouts
The slot has an above-average RTP of 96.01% and a 10,000x top prize. It is a highly volatile game, so don’t expect the jackpot to come easily. You’ll need lots of luck on your side to get close to it, so cross your fingers before you start spinning.
