Abstract

An improved vacuum crane game and method. Multiple prizes are provided on a rotating turntable. A player may control horizontal movement of a vacuum pick-up device positioned above the prize area. The pick up device includes a vacuum head that may be raised and lowered relative to the turntable in a z-direction. The vacuum head is used to pick up one of the prizes using a suction force that is provided by a vacuum pump coupled to the vacuum head by a hose and located away from the vacuum head. In one embodiment, a vacuum sensor in the vacuum head may sense whether a prize is picked up. The pick-up device is moved to a dispenser area and the suction force is removed to allow the prize to fall to a conveyor device, which moves the prize to a dispenser where it is delivered to the player.
