Cascading wins: Hit a qualifying group and the symbols vanish, then new ones tumble in. A single spin can snowball into a chain of wins when the grid refills well.
Multiplier symbols: Multipliers can land during the base game and bonus. Values range from 2x up to 1,000x, and they boost the total tumble win when they show up together.
Power symbols: Power symbols turn to stone and destroy low-frequency symbols to force fresh drops, with different levels removing symbols that appear only once, once or twice, or once through three-of-a-kind.
Bonus Spins: Land 4/5/6 Bonus (scatter) symbols to trigger 10/15/30 free spins. During the feature, multiplier values are collected into a running global multiplier that applies to wins, and extra Bonus symbols can extend the round.
