20110272887 | DIRECT PRIZE-DISPENSING GAME WITH CRANE DISPENSER - A direct prize-dispensing game dispenses prizes using a crane assembly under control of the game player. The player participates in an underlying game of the prize-dispensing game that is independent from the prize dispensing function of the crane assembly. When the player successfully achieves an object of the game entitling the player to a prize, the prize-dispensing game switches player control to the crane assembly for dispensing an associated prize selection. The player then controls the crane assembly to select a desired prize. The prize-dispensing game keeps the controls to the crane assembly until a prize is dispensed to the player. | 11-10-2011 |

20120187187 | TWO-WAY SYMBOLOGICAL COMMUNICATION BETWEEN ELECTRONIC DEVICES - Symbological communication operates to communicate information and data between mobile and electronic devices. Using certain information, an optical symbology is generated and displayed on the display screen of the mobile device. The optical symbology is read by an optical scanner coupled to the electronic device to read the optical symbology and decode the information contained therein. The electronic device uses the decoded information for different tasks, including providing authorized access to additional functionality of the electronic device by the user. After user interaction with the electronic device, it generates another optical symbology for on its display screen. The user of the mobile device would then capture the image of this optical symbology using the camera function of the mobile device. Applications operating on the mobile device decode all of a part of the additional information for local use or to communicate further to remote servers for additional use or tracking. | 07-26-2012 |

20150105130 | IMAGE MATCHING GAME - An image matching game is described that provides multiple game display elements to a user. Each display element cycles through displaying one of a plurality of images. The user provides input to stop the changing display on one image. With each successive game display element, the user tries to stop the changing images on the same image as the previous display elements. When the user successfully stops the changing display elements and matching images across the game display elements, the user receives an indicia of reward. If the user fails to successfully match the image on any one element in the series of game display elements, the game turn either ends or the user loses one of a set number of attempts provided by the game. Depending on the implementation of the game, the user may receive interim level rewards for matching fewer than all of the game display elements. | 04-16-2015 |
