Abstract: An electronic gaming device is provided. The gaming device includes a processor. The processor is programmed to: in response to transitioning to a feature game, cause one or more trigger symbols displayed on a reel display to transition to a credit symbol that includes a credit value wherein the credit value is determined by performing a lookup within a first award table, cause the reel display to spin causing a new trigger symbol to be displayed, cause the new trigger symbol to transition to a new credit symbol; and if a total number of credit symbols displayed on the reel display meets a first threshold value, assign a new credit value to the new credit symbol by performing a lookup within a second award table, wherein the second award table includes credit values that are greater than the credit values of the first award table.
