These bubbles can release a boom of WILDS on 5 reels with the special Fruit Match Feature.
WILD substitutes for all symbols except the STAR symbol (Scatter). FRUIT MATCH FEATURE: With every spin 5 random symbols (all except SCATTER and WILD) appear in the bubbles above the reels. If a symbol on a reel matches the symbol in the respective bubble above, it turns into a WILD. Symbols in the bubbles above the reels do not participate in winning combinations.
