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.

Abstract: The user can attach a stamp without a predetermined postage to an article to be mailed. The stamp has a top layer having a visual display, middle layer having an electronics layer, and a bottom layer having an adhesive layer. The stamp is encoded such that the visual display of the stamp is altered to indicate a state of the stamp. Postage of the article is determined by a postal authority worker and payment is authorized using the unique identifier. This eliminates the need for the sender to have any personal interaction with a postal worker to ship an article and eliminating the need for the sender to estimate postal cost prior to the article being received at the postal office. Altering the adhesive layer provides safe removal of the affixed stamp which can then be reused.
