123 Boom! Slot Features Explained
Wild Symbol: The Cannonball Wilds appear when a win is not achieved, destroying existing symbols and sliding in new ones from the left to potentially create guaranteed wins. These wilds can trigger additional explosions and cascades, enhancing the chain reaction mechanic during base play.
Scatter Symbol: The Scatter triggers the Free Spins bonus round, though it is described as hard to catch. Once activated, the multiplier starts at 2x and increases with each consecutive win, potentially reaching up to 99x. Wins continue to trigger explosions and sliding symbols, and wilds may re-enter from the left to ensure continued action even after a dry spell.
