Abstract
A gaming machine comprises a symbol selector for selecting a plurality of symbols from a set of symbols for display during play of a base game, the set of symbols including a plurality of non-configurable symbols and a plurality of configurable symbols; a random number generator for generating random prize values; a value assigner for assigning a generated random prize value to each selected configurable symbol; and an outcome evaluator for monitoring play of the base game, wherein a feature game is triggered in response to a trigger event, the trigger event comprising a predefined number of the plurality of configurable symbols being selected by the symbol selector for display. During the feature game, the symbol selector is further configured to 1) hold the selected configurable symbols that comprise the trigger event on the display; 2) remove at least one of the selected non-configurable symbols from the display; and 3) replace any removed non-configurable symbol with another symbol selected from the set of symbols.
