In a first embodiment the pivot axis is substantially centered between adjacent edges of the door and walls with an inner face of the hinge being in the same plane as the door and wall to fill a gap therebetween. The first embodiment has a base portion that extends into a hollow wall support and fastens to the inside thereof. A second embodiment has a base portion that fastens to a wall fin substantially centered in the gap and forms a part of the playing surface. A third embodiment has a base portion projecting rearwardly of the stationary second leaf portion, attaches to the back side of a support fin and utilizes a notch in the wall.
