Abstract: A gaming device includes a processor and a memory storing symbol data, trigger probability data for wager options, and instructions. The symbol data includes reel strips including positions dynamically configurable with trigger symbols associated with feature games, and trigger symbol sets including different versions of the trigger symbols and corresponding to the wager options. The instructions, when executed, cause the processor to receive a selected wager option; configure the reel strips by selecting a trigger symbol from the trigger symbol set corresponding to the selected wager option for the dynamically configurable positions; select symbols from the configured reel strips for display in symbol positions; control display of the selected symbols; and upon the selected symbols including a trigger symbol associated with a feature game, determine whether the feature game is triggered based on the trigger probability data for the selected wager option and an identity of the trigger symbol.

Abstract: A gaming device comprises a display, a random number generator, a processor, and a memory storing instructions. When the instructions are executed by the processor, they cause the processor to conduct a base game from which feature games and at least one composite feature game can be triggered, where the composite feature game comprises game play characteristics from a first feature game and a second feature game of the feature games, and the composite feature game comprises a combination of the different game play characteristics. The composite feature game is initiated in response to a composite feature trigger condition being met. The game instances are presented with one or more feature game icon, which are modified in presentation during the game instances in accordance with an associated game play characteristic for a particular instance.
