  • Patent number: 6554277
    Abstract: An amusement device including a sheet of flexible material defining an opening, and a pocket defining a mouth joined to the sheet around the opening. The sheet is grasped by participants during a game in which the sheet is held substantially horizontally and selectively tilted to maneuver a ball along the sheet, through the opening, and into the pocket. In one embodiment, the amusement device includes first and second sheets of flexible material joined along their respective longitudinal edges. Each sheet defines an opening. A pocket may optionally be joined to the sheet around each opening. A game may be played by opposing teams, each of which guards the opening on its sheet, and attempts to guide the ball into the opening on the opposing team's sheet. A game including an amusement device and a ball is also provided.
