  • Publication number: 20240112527
    Abstract: In one aspect, an electronic gaming system that includes at least one memory device with instructions stored thereon, and at least one processor in communication with the at least one memory device, wherein the instructions, when executed by the at least one processor, cause the at least one processor to display a game interface including a game matrix and generate a game outcome of a base game comprising a plurality of displayed symbols within the game matrix. The displayed symbols include at least a first symbol and a second symbol. If a wild symbol is displayed on a spin, a counter configured to track a number of displayed wild symbols over a predetermined period of time is incremented. If the number of counted wild symbols satisfies a threshold within the predetermined period of time, the second symbol is converted to or replaced by the first symbol.
