System and Method of Providing a Hold and Spin Feature Game with Iterative Awards

A method, comprising:

• determining, by a controller, a base game outcome and corresponding display symbols, the display symbols selected from a base game symbol set;
• presenting, via a display device, the base game outcome;
• determining, by the controller, that a feature game trigger condition exists when the base game outcome comprises at least a quantity of trigger symbols;
• presenting, via the display device, a feature game having a first quantity of instances;
• and
• for each instance of the feature game,
• determining an outcome and corresponding display symbols for the instance, the display symbols selected from a feature game symbol set comprising configurable symbols and non-configurable symbols;
• holding each displayed configurable symbol at its corresponding display symbol position for any remaining instance of the feature game;
• and
• based on determining that the outcome for the instance includes at least two additional configurable symbols, determining a first award amount and a second award amount, the first award amount based on values of the configurable symbols held from previous instances, the second award amount based on the first award amount and a first of the at least two additional configurable symbols.

One or more non-transitory media having software stored thereon, the software including instructions for controlling one or more devices to perform a method, the method comprising:

• determining, by a controller, a base game outcome and corresponding display symbols, the display symbols selected from a base game symbol set;
• presenting, via a display device, the base game outcome;
• determining, by the controller, that a feature game trigger condition exists when the base game outcome comprises at least a quantity of trigger symbols;
• presenting, via the display device, a feature game having a first quantity of instances;
• and
• for each instance of the feature game,
• determining an outcome and corresponding display symbols for the instance, the display symbols selected from a feature game symbol set comprising configurable symbols and non-configurable symbols;
• holding each displayed configurable symbol at its corresponding display symbol position for any remaining instance of the feature game;
• and
• in response to determining that the outcome for the instance includes at least two additional configurable symbols, determining a first award amount and a second award amount, the first award amount based on values of the configurable symbols held from previous instances, the second award amount based on the first award amount and a first of the at least two additional configurable symbols.
