Abstract

A cascading symbol game includes designated symbols such as wild symbols. In the cascading symbol game, a gaming device generates and displays a symbol from a plurality of symbols for each of a plurality of symbol positions. The gaming device removes at least one symbol from at least one of the plurality of symbol positions. The gaming device repositions at least one displayed symbol to another one of the symbol positions to create at least one empty symbol position. If a designated event occurred, the gaming device generates and displays at least one designated symbol, such as a wild symbol, in the at least one empty symbol position, wherein the at least one designated wild symbol is generated independent of the plurality of symbols. The gaming device displays any award associated with any winning symbol combination formed from the displayed symbols.
