Gaming machine with symbol enhancements based on winning outcomes

摘要

A wagering game in a gaming machine includes symbols that are associated with multiple payoff levels. The symbols may have their payoff levels incremented and decremented based on certain predefined criteria. The criteria may be based on a winning outcome, random selection, the position of the symbols, the configuration of the symbols, and the like. As some symbols have their payoff levels incremented, other symbols have their payoff levels decremented. Each symbol may be graphically rendered in a manner to distinctively indicate the particular payoff level currently assigned to that symbol. In this way, the wagering game maintains a dynamic mix of symbols having different payoff levels and graphical renderings.
