Nailed It! Games brings the raw power of North American wildlife to life in Unstoppable Bison, a high-energy slot that introduces an innovative sticky movement mechanic. This 5×4 grid slot combines classic casino elements with modern gameplay features that center around the majestic bison symbol.
The game operates on a 40-payline structure where winning combinations form from left to right. What sets this slot apart is its dynamic RESPIN! feature, which activates when four Bison symbols stack to cover an entire reel. These mighty beasts then demonstrate their unstoppable nature by charging to the leftmost available positions on their respective rows, while remaining sticky throughout the feature. The respins continue until either no new Bison symbols appear or the entire grid fills with these powerful symbols.
The game introduces a unique Stars Collection system where Bison symbols may appear with special star markings. This progressive collection mechanism increases players’ chances of triggering the Bonus game, with collection progress saved separately for each bet level. When triggered, players face an exciting wheel divided into colored segments, offering four different jackpot tiers: Mega (5,000x), Major (200x), Minor (40x), and Mini (10x).
Landing three or more Free Spins symbols unleashes a special bonus round where the reels transform to feature only Bison symbols and blank positions. The number of free spins awarded scales with the trigger symbols: 5 spins for three symbols, 6 for four, and 7 for five. During this feature, the Bison movement mechanic remains active, with all Bison symbols shifting to the leftmost available positions and staying sticky throughout the bonus.
Strategic Wild symbols appear exclusively on reels 2, 3, and 4 during the base game, substituting for all symbols except Free Spins and Bison symbols during feature triggers. While these Wilds don’t offer direct payouts, they play a crucial role in completing winning combinations across the game’s 40 fixed paylines.
Drawing inspiration from the majestic landscapes of North America, Unstoppable Bison’s visual design captures the raw beauty of the western frontier. The game’s 5×4 grid is framed by an ornate wooden structure adorned with Native American-inspired decorative elements, while the background showcases dramatic red rock formations against a vibrant blue sky. The color palette expertly blends warm sunset tones with cool mountain hues, creating an immersive atmosphere that transports players to the untamed wilderness.
The symbol set features a carefully curated selection of North American wildlife, each rendered with exceptional detail. The high-paying symbols showcase the region’s most iconic creatures: the mighty bison rendered in rich browns with a fierce expression, the alert fox with its distinctive russet fur, the majestic bald eagle portrayed with striking white head feathers, and the noble elk with its impressive antlers. These premium symbols are complemented by the classic card royals (A, K, Q, J) styled with a western flair.
Experience the raw power of nature in Unstoppable Bison, where mighty beasts charge across the reels in this innovative slot featuring sticky respins, progressive star collections, and multiple jackpot opportunities through an exciting wheel bonus.
