Abstract
Abstract A numerical manipulation board game, with: a game board ruled with at least two generally rectangular grid cells of uniform size; at least two playing tiles of uniform size, each being a block having at least two faces upon which the respective block may rest; each block being so shaped that, when both rest on one such face thereof on the game board, the two grid cells are both substantially filled and that, when both rest on another such face thereof and adjacent one another on the game board, one of the grid cells substantially contains both of the playing tiles; indicia on the playing tiles, so located that the indicia is apparent to observers regardless which of the two faces either playing tile rests upon. When the board includes a plurality of cells arranged in a rectangular grid the board game may be used with additional sign tiles to construct interlocking mathmatical equations vertically, horizontally and diagonally on the grid.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
198 words
A numerical manipulation board game, comprising: a game board ruled with a plurality of generally rectangular grid cells of uniform size; a plurality of playing tiles each constituted by a generally rectangular block having a plurality of mutually perpendicular adjacent sides, some ones of said sides being substantially as long and substantially as wide as individuals of said grid cells and the remainder of said sides being substantially as extensive in one dimension as the comparable dimension of individuals of said grid cells and so inextensive in the other dimension that more than one such block may rest side-by-side on such remaining sides within individuals of said grid cells; at least one of the first-described sides and at least one of the last-described sides bearing an item of numerical indicia, whereby the block may rest in a grid cell upon a firstdescribed side, substantially fill the cell and have an item of numerical indicia presented upward for viewing, and the block may rest in a grid cell upon a last-described side beside at least one other such block so disposed, together substantially filling the cell and having a multiple character item of numerical indicia presented upward for viewing.
Claim 2
Dependent Claim
198 words
A numerical manipulation board game, comprising: a game board ruled with a plurality of generally rectangular grid cells of uniform size; a plurality of playing tiles each constituted by a generally rectangular block having a plurality of mutually perpendicular adjacent sides, some ones of said sides being substantially as long and substantially as wide as individuals of said grid cells and the remainder of said sides being substantially as extensive in one dimension as the comparable dimension of individuals of said grid cells and so inextensive in the other dimension that more than one such block may rest side-by-side on such remaining sides within individuals of said grid cells; at least one of the first-described sides and at least one of the last-described sides bearing an item of numerical indicia, whereby the block may rest in a grid cell upon a firstdescribed side, substantially fill the cell and have an item of numerical indicia presented upward for viewing, and the block may rest in a grid cell upon a last-described side beside at least one other such block so disposed, together substantially filling the cell and having a multiple character item of numerical indicia presented upward for viewing.
Claim 3
Dependent Claim
29 words
The board game of claim 1 wherein each such block is substantially half as thick as it is long and wide and each such grid cell is substantially square.
Claim 4
Dependent Claim
91 words
The board game of claim 1 further comprising: an additional plurality of game board playing tiles each constituted by a block sized to fit in individual ones of said generally rectangular grid cells, each such block having at least one face whereupon the block may rest in individual ones of said generally rectangular grid cells and at least one other face provided with an item of mathematical instruction exemplified by an instruction to ''''add'''' an instruction to ''''subtract'''', an instruction to ''''multiply'''', an instruction to ''''divide'''' and an instruction to ''''equate''''.
Claim 5
Dependent Claim
79 words
The board game of claim 3 wherein the grid cells are Compactly arranged in a rectangular grid of columns and rows thereof, alternating ones of the individual grid cells in alternating rows and columns of the grid being of sensibly different appearance 30 than the remainder 32 of the individual grid cells to establish a definite pattern for construction of physical representations of mathematical equations on the game board using the first-described and second-described playing tiles in mutual conjunction.
Claim 6
Dependent Claim
168 words
A numerical manipulation board game, comprising: a game board ruled with at least two generally rectangular grid cells of uniform size; at least two playing tiles of uniform size, each being a block having at least two faces upon which the respective block may rest; one such face of each block being of substantially said grid cell uniform size and another such face being as long or wide as said one face thereof, but of half said uniform size; two of said grid cell playing tiles, when both rest on one such face thereof on said game board, substantially filling two said grid cells and, when both of said playing tiles rest on said other such face thereof and adjacent one another on said game board, both being substantially contained within one of said grid cells; means providing indicia on at least two faces of each of the playing tiles, so that the indicia is apparent to observers regardless which of the faces either playing tile rests upon.
Claim 7
Dependent Claim
168 words
A numerical manipulation board game, comprising: a game board ruled with at least two generally rectangular grid cells of uniform size; at least two playing tiles of uniform size, each being a block having at least two faces upon which the respective block may rest; one such face of each block being of substantially said grid cell uniform size and another such face being as long or wide as said one face thereof, but of half said uniform size; two of said grid cell playing tiles, when both rest on one such face thereof on said game board, substantially filling two said grid cells and, when both of said playing tiles rest on said other such face thereof and adjacent one another on said game board, both being substantially contained within one of said grid cells; means providing indicia on at least two faces of each of the playing tiles, so that the indicia is apparent to observers regardless which of the faces either playing tile rests upon.
Claim 8
Dependent Claim
37 words
The board game of claim 5 wherein each tile has at least two additional faces respectively generally parallel to the two first-recited faces; the indicia being constituted by a single character provided on each said additional face.
Claim 9
Dependent Claim
28 words
The board game of claim 6 wherein the characters on the two additional faces on the blocks are of identical denotation for each individual one of the blocks.
Claim 10
Dependent Claim
81 words
The board game of claim 5 wherein the characters are each one digit numbers so that when both blocks have the respective one face thereof face down on the game board, both grid cells are filled with tiles indicating one digit numbers and when both blocks have the respective other face thereof face down on the game board so that one grid cell substantially contains both blocks so that such grid cell is filled with tiles indicating a two digit number.
