Jack Hammer 4 takes the detective noir series to Chinatown with a 6x6 grid and cluster pay mechanics. The Sticky Win feature locks winning clusters and Scatters for re-spins until nothing new lands. Corner positions hold special Wilds that trigger four different features - Expander, Upgrader, Multiplier, and Cash Prize.

Free Spins are triggered by 5 Scatters and start with 3 multipliers on the reels. The corners transform into four feature triggers (Unlock, Generate, Double, Collect) that activate when multipliers land adjacent to them. Unlock expands the grid vertically, Generate adds random multipliers, Double does what it says, and Collect totals everything up.

The game offers five Elevate Features ranging from doubled Free Spins chances to guaranteed Super Free Spins. RTP sits at 96.03% with high volatility and a max win of 10,000x your bet.
