Clusterbuck is a 6x6 cascading slot built around the fast-paced Cluster Chase system. Symbols can appear as singles, doubles, or quads, creating chain reactions and increasing Tier Pays as clusters grow. Each winning symbol adds to the Cluster Bar, unlocking higher-tier rewards. Bomb symbols explode to reshuffle the grid, sparking fresh cascades. Padlock symbols hold clusters in place for extended combinations. In Free Spins, Wilds can split into doubles and quads for larger cluster formations. The Chest Bonus can add extra Wilds, and the Jackpot Wheel offers the chance to land one of four jackpots. Vivid visuals and energetic sound design keep the pace high from the first spin to the last.
