发明名称 Channeled pivoting ball game with selective hole closure
摘要 A table height rolling ball game apparatus of the type employing a freely tippable table whose upper surface has a maze defining a track on which a ball may freely roll is disclosed. The track runs circuously from an outer start position to a central end position and a number of hazard holes are provided in the track. The hazard hole and track are sized such as to allow the ball to roll past the hazard hole when rolling along one sidewall of the track, but to fall into and through the hole when proceeding along the other side of the track. At least some of the holes are placed along the side walls where the ball would naturally travel so as to require a coordinated action on the part of the player or players to avoid them. A novel hole closing system is employed to selectively close the hazard holes so that the game may be made easier or harder. Further, a restricted-movement free-wheeling wheel (to prevent torque applications) is provided for play by a team of two, wherein the pair of players must cooperate and coordinate their movements to position and move the table.
