Abstract: A constrained puzzle device including a housing formed with a radial crescent gutter; one or more slots providing an opening from an outer edge of the housing toward a centerline of the housing; a cartridge wheel nested within the slot and rotatably coupled to the housing, the cartridge wheel having multiple channels passing therethrough. The constrained puzzle device further includes one or more dials rotatably coupled with the housing, the dials configured with structures extending at least partially over the crescent gutter to create one or more pocket regions. Puzzle objects can be disposed within a channel of the cartridge wheel and the slot of the housing, or within the crescent gutter of the housing and a pocket formed by at least one arm member of the dial. The puzzle objects can be moved around in the constrained puzzle device as a user rotates the dials and/or the cartridge wheels.
