Abstract: A portable controller accessory that is usable in various states is disclosed. The controller accessory may have an idle (closed) state where the upper case element is closed relative to the lower case element. The controller may have an active (open) state wherein the lower case element is partially slid out from the upper case element to expose the controller's control elements for gaming and place the control elements in a location suitable for a user's hands/fingers to operate the control elements during gaming. Additionally, the controller can be placed in a detached state where the upper and lower case elements are completely detached from one another. In the detached state, the lower case element with its gaming controls can be used with another gaming system, or it can be used with the phone at a distance from the controller.
