Abstract: A game apparatus, comprising a body, having a rotational axis and a non-planar surface, and a support, is disclosed. The support supports the body in a starting position, whereat the axis is horizontal, a center of gravity of the body is below the axis and the surface presents upwardly, and enables the body to rotate about the axis through a range of rotation. Playing pieces are provided. The surface includes playing positions, a socket being provided at each playing position, for releasably retaining selected ones of the playing pieces in fixed position relative to the surface upon selective distribution of said selected ones of the playing pieces to respective ones of the playing positions. The body is adapted for variable pivotal displacement about the axis relative to the starting position by effect of gravity responsive to said selective distribution. A scale for measuring said variable pivotal displacement is also provided.
