A compact, easy-to-use and space-saving case for a main unit of a palm-size game that provides the combined functions of a retractable handle, a storage tray, and a protection case, and is essentially comprised of a lower lid and an upper lid with the main unit fixed between; the upper lid is removed and the case can turn 180 degrees in reverse direction while the lower lid serves as the rail and the groove on the upper lid serves as the track to create a drawer type storage tray for accommodating a game cartridge while both lids and the main unit define a retractable trapezoid handle.
