Steamrunners
Steamrunners is a steampunk-themed slot developed by Hacksaw Gaming, set in floating cities filled with rogue airships. The game takes place on a 5x4 grid that uses traditional paylines. In the base game, players can land Green or Purple Gas Canisters to transform symbols into spreading or multiplier wilds. The primary free spins features are triggered by landing three to five scatters, awarding between eight and ten spins with enhancements like sticky wild multipliers or guaranteed gas canisters.
