Concentration number board game apparatus

Claim 1

A concentration number board game apparatus comprising: a game board having a flat top playing surface, a flat bottom surface, opposed longitudinally extending side edges, and opposed transversely extending end edges; the game board being divided in half along its longitudinal axis between said end edges into two separate portions to provide identical opposing game playing portions for two individual players of the game; hinge means connecting together the two separate game board portions along said dividing line to permit folding of the game board onto itself for ease of storage and transportation; a first row of twelve side-by-side squares extending completely along the associated side edge of each half of said game board top surface between opposite end edges of the game board; a second row of twelve squares extending adjacent to said first row between opposite ends of each half of said game board top surface with each square of said second row in transverse alignment with an associated square of said first row; a set of four penalty squares provided on each half of said game board top surface adjacent one end of said second row of squares thereon; a longitudinally extending set of six squares disposed on each half of said game board top surface extending parallel to said associated first and second rows of squares and disposed intermediate said opposite end edges of said game board top surface and spaced transversely from said associated second row of squares; the grouping of playing squares on each half of the game board top surface being identical when that particular half portion is viewed from the associated side edge thereof; a first set of playing pieces; a second set of playing pieces distinguishable from said first set of playing pieces; each of said playing pieces in said first and said second sets of playing pieces being identical in size and configuration with each of a size to be completely received within the boundary of an associated square on said playing surface when the playing piece is placed thereon; each playing piece being of a flat circular configuration having a flat face surface, a flat back surface, and a circular peripheral edge surface; each set of playing pieces including a total number of 12 playing pieces therein; each playing piece of each set of playing pieces being numbered with the numerals 1 through 12 respectively on said face surface thereof for clearly identifying each playing piece of each set from each other playing piece of the same set; the back surface of each of said playing pieces of each set being identical in appearance to each other so as to be non-distinguishable when said playing pieces are rested in a face down manner on said game board to conceal said numeral marked thereon; and the playing pieces of said first set of playing pieces being of a different color than the playing pieces of said second set of playing pieces to provide ease of readily distinguishing the first set from the second set.
