Saddle up and embark on a dusty trail to riches with 'Fuel the Mule', Yggdrasil's rugged and spirited slot that plunges you into the heart of the Wild West gold rush. The reels are carved into the red rock of a sun-baked canyon, with rickety mine shafts and ancient cacti dotting the landscape, all under a vast, azure sky. A twangy, harmonica-laced soundtrack conjures images of tireless prospectors and the promise of hidden gold. Symbols include weathered prospectors, gleaming gold nuggets, dynamite sticks, and the titular, determined mule, who proves to be an invaluable companion on your quest for fortune in this unforgiving frontier. This western adventure is driven by the innovative 'Hold & Win' Respins feature, ignited when enough 'fuel' symbols – typically gold nuggets or special collectibles – land, locking into place as you spin for even more valuable treasures. Each new fuel symbol resets the respins, intensifying the hunt for the ultimate jackpot as the screen fills with shimmering gold. The Free Spins round unleashes even greater potential, perhaps with expanding wilds or increasing multipliers, turning barren plains into fields of gold. 'Fuel the Mule' masterfully captures the relentless spirit of the frontier, where perseverance and a touch of luck transform arduous prospecting into an exhilarating haul of riches, making every spin a step closer to unearthing a mother lode of wins.
