Abstract
The gaming device and method disclosed herein have a plurality of reels and at least one expanding and roaming wild symbol. The wild symbol moves relative to the reels to provide additional award opportunities. When both the wild symbol and a designated trigger symbol appear on one of the reels, the wild symbol expands to form an expanded wild symbol set that includes a plurality of individual wild symbols. The designated trigger symbol determines the number of moves. For each move, the expanded wild symbol set moves to one of the reels. That is, the expanded wild symbol set enables a plurality of individual wild symbols to randomly move from reel to reel for a number of moves, wherein the number is determined based on the designated trigger symbol. After each move, the gaming device performs an award evaluation to determine whether a winning combination is displayed on the reels.
