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.

Claim 1
Independent Claim
157 words
In game apparatus employing a plurality of blocks for balancing, the improvement comprising: all said blocks being respective identical oblique quandrangular prisms in shape; the proportions of each block being such as to permit stacking first and second of said blocks on the oblique faces thereof with the rectangular shape faces in-plane, without tipping over, but such as to cause tipping over of the stack when a third said block is added to the top of said stack with the rectangular shape faces thereof in-plane with those of the first and second blocks, a plurality of parallel-spaced indicia on each block parallel with one or more faces thereof but vertically inclined, said parallel spacing of the indicia being uniform; said proportions of each block being as follows: the ratio of the standing height to the perpendicular distance between rectangular faces being three-to-two, and the acute angles of the bases of the prism shape being substantially 75.5 degrees.

In game apparatus employing a plurality of blocks for balancing, the improvement comprising: all said blocks being respective identical oblique quandrangular prisms in shape; the proportions of each block being such as to permit stacking first and second of said blocks on the oblique faces thereof with the rectangular shape faces in-plane, without tipping over, but such as to cause tipping over of the stack when a third said block is added to the top of said stack with the rectangular shape faces thereof in-plane with those of the first and second blocks, a plurality of parallel-spaced indicia on each block parallel with one or more faces thereof but vertically inclined, said parallel spacing of the indicia being uniform; said proportions of each block being as follows: the ratio of the standing height to the perpendicular distance between rectangular faces being three-to-two, and the acute angles of the bases of the prism shape being substantially 75.5 degrees.
Claim 3
Independent Claim
58 words
The method of playing a balancing game consisting of the steps: a. forming a stack of a plurality of identical blocks of oblique quandrangular prism shape; b. lifting the stack by the lowermost block thereof; and c. depositing the stack upon a single said block in balance preventing the stack from toppling over; thereby playing said balancing game.
