A gaming system comprises a processor and memory storing a) multiple feature game trigger probability states including a lowest feature game trigger probability state and a highest feature game trigger probability state; b) a current feature game trigger probability state of the multiple feature game trigger states; and c) instructions. When the instructions are executed, they cause the processor to receive a player selection in respect of play of a game with a base game from which a feature game can be triggered, generate a base game outcome for display, evaluate the base game to determine whether to make an award in respect of the base game, and control a probability of the feature game being initiated (e.g., select the current feature game trigger probability state if the player selection has a first characteristic, or the highest feature game probability state if the player selection has a second characteristic).
