The EXPANDING WILD-COLLECT SYMBOL is a mechanic where a WILD symbol lands on the 3rd reel, expands to the entire reel, and collects MONEY symbols
When 3 BONUS symbols appear on the reels during the regular game, the player enters the bonus game with FREE SPINS. In the BONUS GAME, the EXPANDING WILD symbol starting from the 5th reel with each FREE SPIN moves to the left and collects MONEY symbols. In addition, during the BONUS GAME, each new WILD landing on the reels expands, moves to the left and collects MONEY symbols. If it has landed to the right of the current WILD symbols, it gives additional FREE SPINS
