Claim 1

A GAME COMPRISING A PLURALITY OF IDENTICAL SIZE BALLS; A CIRCULAR, HORIZONTALLY ARRANGED BASE HAVING AN UPSTANDING CONTINUOUS ANNULAR RIM ALONG ITS UPPER PERIPHERAL EDGE TO FORM A CIRCULAR, CONTINUOUS OUTER WALL; THE UPPER SURFACE OF THE BASE FORMING A PLAYING SURFACE WHICH IS UNIFORMLY SLOPED UPWARDLY IN ALL RADIAL DIRECTIONS FROM ITS CENTER UP TO THE OUTER WALL; A CIRCULAR INNER WALL FORMED ON AND EXTENDING UPWARDLY FROM THE PLAYING SURFACE AND ARRANGED WITHIN THE CIRCUMFERENCE OF AND PARALLEL TO THE OUTER WALL AND BEING UNIFORMLY SPACED FROM THE OUTER WALL A DISTANCE WHICH IS ONLY SLIGHTLY GREATER THAN THE DIAMETER OF A BALL SO THAT A BALL MAY ROLL BETWEEN THE WALLS ON A CIRCUMFERENTIAL PATH RELATIVE TO THE CENTER OF THE BASE AND WILL COME TO REST IN ONE OF THE DEPRESSIONS IN ITS ROLLING PATH; AN OUTER SERIES OF EQUALLY SPACED APART HEMISPHERICALLY SHAPED DEPRESSIONS FORMED IN THE PLAYING SURFACE, EACH DEPRESSION BEING EQUALLY SPACED BETWEEN THE TWO WALLS, THE DEPRESSIONS TOGETHER FORMING A COMPLETE CIRCLE COMPOSED OF REGULARLY RADIALLY SPACED APART RECEPTACLES FOR RECEIVING BALLS; AN INNER SERIES OF HEMISPHERICALLY SHAPED DEPRESSIONS FORMED IN THE PLAYING SURFACE CLOSELY ADJACENT TO BUT WITHIN THE CIRCUMFERENCE OF THE INNER WALL AND TOGETHER FORMING A COMPLETE CIRCLE OF REGULARLY RADIALLY SPACED APART BALL RECEIVING RECEPTACLES PARALLEL TO THE OUTER SERIES CIRCLE AND THE INNER WALL, WITH EACH OF THE DEPRESSIONS OF THE INNER SERIES BEING LOCATED ON A RADIUS WHICH IS EQUIDISTANTLY SPACED BETWEEN THE TWO RADII ON WHICH ARE LOCATED TWO ADJACENT DEPRESSIONS OF THE OUTER SERIES DEPRESSIONS, THERE BEING THE SAME NUMBER OF DEPRESSIONS IN EACH SERIES; THE INNER WALL BEING FORMED WITH RADIALLY DIRECTED GAPS FORMING OPENINGS WHICH EXTEND UPWARDLY FROM THE PLANE OF THE PLAYING SURFACE TO THE UPPER EDGE OF THE INNER WALL, EACH GAP BEING RADIALLY ALIGNED WITH AN OUTER SERIES DEPRESSION AND BEING OF A WIDTH WHICH IS ONLY SLIGHTLY GREATER THAN THE DIAMETER OF A BALL SO THAT A RADIALLY DIRECTED BALL MAY ROLL THERETHROUGH; A MANUALLY ROTATABLE SPINNER, HAVING A SERIES OF SPACED UPRIGHT EDGES, ARRANGED FOR MANUALLY ACTUATED ROTATION AT THE DEPRESSED CENTER OF THE PLAYING SURFACE FOR STRIKING THE BALLS AND DIRECTING THEM TO ROLL INTO VARIOUS OF THE DEPRESSIONS, THERE BEING LESS BALLS THAN THERE ARE DEPRESSIONS; IDENTIFICATION MEANS IDENTIFYING THE DEPRESSIONS INTO GROUPS, AND INCLUDING INDICIA INDICATING A MATHEMATICAL VALUE AND MATHEMATICAL FUNCTION FOR EACH OF THE DEPRESSIONS IN EACH GROUP, FOR COMPUTING THE MATHEMATICAL VALUES OF THE DEPRESSIONS WHICH RECEIVE A BALL IN ANY ONE GAME INTO A GAME SCORE.
