How the Game Plays

This canine-themed slot from Iron Dog Studio features three elite operatives—Baxter, Ronnie, and Mobi—set against an airfield backdrop. The 5x3 grid focuses on a dual-bonus structure, where symbols represent both standard play and high-stakes collection. Players aim to trigger the Hold & Win mode, where special colored coins grant unique modifiers: blue coins collect all current values, green coins transform into mystery jackpots, and red coins expand the grid area. Free Spins Explained

Triggered by landing 3 or more scatter symbols, this feature awards 8 free spins, allowing the K-9 characters to grow in size when their corresponding colored coins land.

Hold & Win Explained

Activated by 6 or more coin symbols, this feature resets the respin counter to 3 with every new coin landed. It incorporates the K-9 character modifiers, which can dramatically boost win values by collecting multipliers or triggering jackpots, including Mini, Minor, and Major tiers.
