Scatter symbols pay anywhere on the reels and also trigger the bonus feature.
Wild Symbol
The Wild symbol substitutes for all regular symbols except the Scatter symbol.
Wilds help complete winning combinations throughout the Base Game and become significantly more powerful during Free Games when stacked Wild reels appear.
Scatter Symbol
Scatter Payouts
