摘要： A crane game with a vacuum head adapted to pick up objects with a smooth extraction surface is disclosed wherein the objects, or targets, include perturbations such as bead shaped projections or dimples that present a more challenging target by reducing the available extraction surface. Disk shaped, spherical, or other shaped targets include one or more perturbations that may prevent a seal from being formed with the suction head, denying extraction of the target by the vacuum head. Values may be assigned to the targets based on the number of perturbations, or the targets may encapsulate prizes of a value directly related to the available extraction surface on the target.
