Year-Round Riches Clusterbuster

Year-Round Riches Clusterbuster by Red Tiger is a 9×9 video slot that uses a cluster pays mechanic, where wins are formed by landing at least five matching symbols connected horizontally or vertically. The grid’s centre holds a 3×3 locked block called the Clusterbuster, divided into four sectors each tied to a season—Spring, Summer, Autumn, and Winter. During base game spins, one season sector may become active at random; forming a winning cluster adjacent to that sector breaks its outer tiles. Clearing the active season sector triggers its unique feature: Spring grants a random multiplier (up to 100×), Summer transforms non-winning tiles into matching symbols, Autumn drops wilds onto the reels, and Winter sends snowballs causing ice cracks that convert symbols. If you break all outer tiles of the Clusterbuster (i.e. clear the whole core), you trigger 10 Free Spins, during which at least one season modifier is active per spin (and up to all four can be active together). Breaking all Clusterbuster tiles again during Free Spins retriggers the bonus with 7 extra spins. There is also a Feature Buy option (outside certain jurisdictions) that lets you either buy a spin with a random season feature or directly access the Free Spins bonus. The theme revolves around the four seasons, with visuals and animations reflecting Spring through Winter in a cohesive, atmospheric design.
