Jack Hammer 4: Chasing the Dragon – Sticky Wins and Feature-Packed Cluster Pays

The city’s neon lights flicker like dragon's breath as Detective Jack Hammer is back on the case in Jack Hammer 4: Chasing the Dragon. NetEnt plunges us into a gritty Chinatown setting where a ruthless mastermind, 'Dragon', plays a deadly game. This high-stakes, action-packed slot is built on a large 6×6 grid and uses the thrilling Cluster Pays mechanic. With High Volatility and a maximum payout of 10,000x your bet.

The Base Game: Sticky Wins and Corner Wild Power

The core gameplay centers around two powerful mechanics that keep the action cycling:

1. Sticky Win™ Re-Spins: This feature triggers whenever you land a cluster win of 6 symbols or more, or when 3 or more Scatters appear. The winning cluster and the Scatters lock in place, and the game grants a Re-Spin. Re-Spins continue as long as new matching symbols join the cluster or additional Scatters land, creating extended win chains and rapid multiplier accumulation.

2. Corner Wild Features: The four corner positions of the 6×6 grid are the keys to unlocking explosive modifiers. These positions can only hold special Question symbols or Wilds. When a corner symbol joins a cluster win, a Wild Feature is activated.

• Expander: Adds up to 4 symbols to the cluster win.

• Upgrader: Upgrades the symbols in the winning cluster to a type with a higher payout.

• Multiplier: Awards random multiplier values (e.g., x2, x3, x5).

• Cash Prize: Awards a random cash prize (e.g., 0.5x to 2.5x the bet) added to the cluster win.

If a Question symbol lands in the corner and joins a win, it transforms into a Wild and activates an even more powerful Super version of these features.

The Bonus Round: Persistent Multiplier Action

The Free Spins round is triggered by landing 5 Scatters, which awards 3 Free Spins to start. This bonus uses a clever "streak" mechanic:

• The round begins with 3 multiplier symbols on the reels.

• Only multipliers can land during Free Spins, and every new multiplier that appears resets the Free Spins counter back to 3.

• Four special features—Unlock, Generate, Double, and Collect—appear in the corners and remain persistent for the duration of the feature. They activate when a multiplier lands next to them:

• Unlock: Expands the play area by adding a top row, then a bottom row, up to a maximum of two times.

• Generate: Places 3 random multipliers on the reels.

• Double: Doubles adjacent multipliers.

• Collect: Sums all multipliers on the reels, removes them, and applies the total value to the win.

Maximize Your Odds with the Elevate Feature

For players looking to control the action, the Elevate Feature offers several strategic buy-in points:

• Wild Activator (10x bet): Guarantees at least one Wild Feature activation, boosting your chances for base game cluster wins.

• Free Spins (100x bet): Instantly triggers the standard Free Spins round.

• Super Free Spins (300x bet): Triggers the ultimate Super Free Spins round directly.

• Lucky Draw (150x bet): Activates either Free Spins or Super Free Spins randomly.

Final Verdict: Will Jack Hammer Crack the Case? (Personal Insight)

Jack Hammer 4: Chasing the Dragon successfully blends its dark, detective theme with intense, modern slot mechanics. The true genius lies in the Sticky Win™ feature. Seeing those 6×6 clusters lock and trigger the Corner Wilds—especially the Upgrader or Expander—is incredibly satisfying and keeps the base game exciting.

However, the real action is in the Free Spins. The combination of the 3-spin reset mechanic and those powerful persistent corner features makes this bonus unique. You're not just crossing your fingers; you're actively watching the Unlock feature expand the grid, the Generate feature fill it with new symbols, and the Double and Collect features working together to smash all those multipliers into one huge payout. If you appreciate games where feature synergy and high volatility reward aggressive play, you absolutely must join Jack Hammer in his chase. It’s a beautifully designed, high-octane slot that delivers a constant feeling of being on the brink of a massive score!
