RTP Year-Round Riches Clusterbuster™ by Red Tiger Gaming is a seasonal cluster slot built around locked tiles on the reels. Winning clusters formed next to the inactive cluster unlock outer tiles, which are split into four sectors: Spring, Summer, Autumn and Winter. During a spin, one sector can become active, and breaking all tiles in that section triggers its seasonal feature.
The bonus features vary by season. Spring can reveal a random multiplier of up to 100x. Summer sends a tidal wave across the reels and turns random non-winning tiles into the same symbol. Autumn causes symbols to transform into wilds. Winter launches snowballs at random symbols, then creates ice cracks that spread vertically or horizontally before turning affected tiles into the original symbol.
The game also includes a free spins round. Clearing the whole Clusterbuster™ awards 10 free spins, with 1 to 4 seasons active on each spin. Clearing all Clusterbuster™ tiles during the bonus retriggers 7 additional spins. A demo version is available to play for free and practice before playing for real money.
