Jack Hammer™ 4: Chasing the Dragon

Jack Hammer™ 4: Chasing the Dragon by Netent is a video slot that uses a 6-column by 6-row grid and "Cluster Pays" mechanics. It is set in a stylized neon-noir Chinatown, featuring a comic book aesthetic and a detective, Jack Hammer, on the trail of a villain known as Dragon. In the base game, there is the Sticky Win™ feature, which activates re-spins when a winning cluster of at least six symbols appears or when three Scatters emerge; the winning symbols and Scatters remain fixed, and the re-spins continue as new symbols are added to the cluster or more Scatters appear. The corners of the board can hold question marks or Wilds; if a corner Wild enters a winning cluster, it activates one of several special features: Wild Expander, Wild Upgrader, Wild Multiplier, or Wild Cash Prize. The question mark symbols can transform into super versions of those features, such as Super Expander or Super Cash Prize. The Free Spins round can be triggered by obtaining five Scatters, which awards three free spins; during this round, only multipliers drop, and each new multiplier resets the spin counter to three, with special features in the corners that activate if a multiplier lands next to them: Unlock, Generate, Double, and Collect. Additionally, there is the Elevate Feature (available in some regions), which allows the player to purchase enhancements such as increasing the chances of Free Spins, activating Wild guarantees, directly accessing Free Spins, or even Super Free Spins. The maximum possible prize reaches up to 10,000 times the bet; total bets can vary between established minimum and maximum amounts per spin depending on the casino.
