Big Bang Boom launches players into a vibrant, futuristic space environment on a 6-reel, 5-row grid using a scatter pays mechanic. Wins occur when a sufficient number of matching symbols land anywhere on the screen, triggering cascading wins that remove winning symbols and bring new ones into play. The game features accumulating multiplier symbols that boost payouts, especially during the free spins bonus round where multipliers do not reset between cascades. This cosmic adventure promises explosive action and stellar winning potential.
