Abstract: A system, method, and gaming machine for implementing an optimized nudge operation. The gaming machine includes a processor for executing a set of instructions to implement a game, a memory for storing the set of instructions, nudge logic for determining an effect of all possible nudge operations on initial results of the game when played by a user, and two hardware nudge buttons for selecting among the nudge operations for the game to change the initial results to a final outcome for the game.

Abstract: A location-based marketing method includes steps of providing at least one first computing device including at least one memory operatively coupled to at least one processor, the at least one memory storing at least a listing of participating vendor geographical locations. At least one second computing device is in computing communication with the at least one first computing device. The method further includes steps of displaying to a user on a display screen of the second computing device a rotatable three-dimensional navigational interface including a plurality of faces, and by a geolocator module of the second computing device, providing to the at least one first computing device a geographical location of the user. The user geographical location is compared to the stored listing of participating vendor geographical locations. On determining a match, the first computing device initiates a user check-in procedure specific to the matching participating vendor.

Abstract: A method and apparatus of selecting derivative strategies, where candidate derivative strategies are selected from a set of essentially all possible derivative strategies available for an underlying, based upon a user's market sentiment for an underlying, to perform favorably under the foreseen conditions being most appropriate to the user's strategic intent and the choices afforded by the relevant markets.
