Abstract

Abstract A mathematical game for play by two or more persons comprises a playing board divided into a series of squares, arranged in rows and columns, each square bearing a number indicia, and a set of playing pieces for each player. Each player piece in a set is marked with at least one number or a non-numeric symbol, at least one playing piece in each set having a non-numeric symbol. Each set of playing pieces is identical to every other set with respect to the number and marking of pieces. The playing pieces are moved from one numbered square to another in a competitive manner, a piece being able to land only in those squares numbered with an integer multiple of at least one of the numerals on the playing piece. The playing piece containing the non-numeric symbol is free to land on any square. Pieces are captured when either: (1) the piece of another player located in the same row or column as the captured piece is moved to the square occupied by the captured piece; or (2) the captured piece was sought to be moved to a square whose number is not an integer multiple of a number on the captured piece, and the incorrect move is challenged by another player.

Claims Analysis

Total Claims: 4
Claim 1
Independent Claim 143 words
A numerical game comprising a game board having a series of demarcated areas arranged in horizontal rows and vertical columns, each of said demarcated areas having a separate, distinct number marked thereon, with said marked numbers each being different from the others and said numbers being organized in said rows and columns; at least two sets of a plurality of playing pieces each piece of a set having indicia marked thereon, each of said sets of pieces having means for distinguishing one set from all other sets; said indicia for a majority of said pieces being at least two identification numbers, which identification numbers each match a symbolically designated number on a selected demarcation area having a number which is a multiple of said identification number; and the other pieces having non-numerical indicia which may be said to match any symbolically designated number.
Claim 2
Dependent Claim 143 words
A numerical game comprising a game board having a series of demarcated areas arranged in horizontal rows and vertical columns, each of said demarcated areas having a separate, distinct number marked thereon, with said marked numbers each being different from the others and said numbers being organized in said rows and columns; at least two sets of a plurality of playing pieces each piece of a set having indicia marked thereon, each of said sets of pieces having means for distinguishing one set from all other sets; said indicia for a majority of said pieces being at least two identification numbers, which identification numbers each match a symbolically designated number on a selected demarcation area having a number which is a multiple of said identification number; and the other pieces having non-numerical indicia which may be said to match any symbolically designated number.
Claim 3
Dependent Claim 34 words
A numerical game as defined in claim 1 wherein said symbolically designated number is designated with a selected color for each integer below a selected integer which forms a multiple of said designated number.
Claim 4
Dependent Claim 14 words
A numerical game as defined in claim 2 wherein said selected integer is 10.
