Abstract: A graphical user interface for providing a game of chance with upgradeable feature symbols and meters reflecting progress towards satisfaction of goals that cause such a feature symbol upgrade.

Abstract: Techniques and systems for providing games of chance with multiple levels of persistent features are disclosed. Some example systems include scatter prize indicators that are each associated with different symbol positions of a game of chance. When a scatter symbol is selected for a given symbol position, the scatter prize indicator associated therewith may be upgraded; selection of a sufficient number of symbol positions may result in a feature game mode being activated. During feature game mode play, scatter symbols are retained after each play of the game until either sufficient consecutive plays occur without any scatter symbols being obtained or until all symbol positions have scatter symbols. In the latter case, the scatter prize indicators are upgraded and play continues. In the former case, the feature game mode concludes. Various enhancements may be triggered based on the number of times that the feature game mode has been activated.
