ABSTRACT:
A center-of-gravity-appraisal game in the form of a set of gauge indicia-marked parallelepiped blocks for stacking by players (or teams) in alternating turns until the stack tumbles, thus designating the player (or team) represented in the previous turn as winning, or until the last remaining block has been successfully balanced on top of the stack, thereby designating the winner or winners. Certain proportions of the blocks are substantially critical for balancing purposes. In preferred embodiment each block is three units high when standing on a base or oblique face of the prism shape by two units deep between rectangular faces. Included acute angles of the bases of the prism shape or oblique faces are preferably 75.5 degrees. Width may conveniently approximate depth. The gauge indicia are parallel-spaced, preferably uniformly, and run parallel with the long dimension of the parallelogram shape and the rectangular shape of the faces of the block.
