How the Game Plays

Jack Hammer 3: Diamond Affair brings the iconic comic-strip detective back in a noir-inspired 1930s New York setting. Unlike its predecessors, this installment utilizes a scatter pays engine where winning combinations are formed by landing eight or more matching symbols anywhere on the 5x6 grid. When a win occurs, the Sticky Wins mechanic locks those symbols in place while the remaining positions respin, continuing as long as new matching symbols or special features appear. The aesthetic maintains the classic hand-drawn art style, accompanied by a moody jazz soundtrack that fits the gritty urban atmosphere.

Free Spins Explained

Landing five or more snake scatter symbols triggers the bonus round, with the number of spins scaling based on how many scatters appeared (up to 20 spins for 10+ scatters). During this feature, any Mystery Multipliers accumulated do not reset between spins, allowing them to grow throughout the duration of the round. Additional scatters during the feature can grant extra spins.

Jack Hammer and Mystery Multiplier Explained

The Jack Hammer symbol acts as a modifier during the Sticky Wins process. If he appears alongside a low-value win, he upgrades all symbols in that combination into higher-value character symbols. If he lands during a high-value win, he activates the Mystery Multiplier bar at the top of the grid. This multiplier increases based on the number of character symbols present, reaching up to 5x or more, and applies to the total win at the end of the respin sequence.
