A pool type game apparatus which has a base structure having a playing surface over which balls or the like may be propelled, with bumper rails surrounding the playing surface. A ball receiving pocket is disposed generally centrally of the playing surface, and a cue stick or other ball propelling device is provided. An arcuate blocking flange protrudes upwardly through the pocket and is selectively movable about a central axis for blocking only a part of the pocket to change the available angles of approach for successfully propelling a ball into the pocket. A polygonal mobile bumper device is positionable on and manually movable bodily over the playing surface to any desired position for directing a ball which is propelled thereagainst, away therefrom at an angle defined by the straight side bumper surfaces of the mobile bumper device.
