• (a) selecting a plurality of sets of symbols for display on a display;
• (b) determining whether the displayed symbols include any winning symbol combination;
• and
• (c) upon determining that the displayed symbols include any winning symbol combination, repeatedly applying a modification rule to at least one of the plurality of sets of symbols until the displayed symbols do not include any winning symbol combination,
• wherein each set of symbols to be displayed is selected from a respective one of a plurality of predetermined source symbol sets, and wherein the modification rule is that a different set of symbols is selected from the plurality of predetermined source symbol sets for each of the sets of symbols to be modified.
