Abstract
Abstract Six-sided cubic blocks with interfitting and repelling sides have selected representations on each side according to predetermined patterns of relationships between side structures and representations. The blocks are assembled in horizontal and vertical arrays to achieve numerical goals of representations on faces of the arrays. Two persons work on the vertical array from opposite sides seeking to attain their own goals, while preventing opposite persons from attaining their goals.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
166 words
Comprehension enhancing apparatus comprising plural cubic blocks having six side faces and engagement means mounted on the blocks on all faces, the engagement means comprising first attachment means and second attachment means selectively positioned on different faces of the blocks, the first attachment means and second attachment means being mutually conjunctive when juxtaposed on faces of adjacent blocks and the first attachment means being repulsive to first attachment means and the second attachment means being neither conjunctive nor repulsive to second attachment means when juxtaposed on faces of adjacent blocks, and a plurality of representation symbols on each block, the representation symbols and the attachment means being organized in a predetermined arrangement, and a base having attachment means for individually holding the first attachment means while not repelling the second attachment means, whereby rows of blocks with interengaged first and second attachment means are arranged on the base with the base attachment means holding the rows by engaging with the first attachment means on individual blocks.
Claim 2
Dependent Claim
166 words
Comprehension enhancing apparatus comprising plural cubic blocks having six side faces and engagement means mounted on the blocks on all faces, the engagement means comprising first attachment means and second attachment means selectively positioned on different faces of the blocks, the first attachment means and second attachment means being mutually conjunctive when juxtaposed on faces of adjacent blocks and the first attachment means being repulsive to first attachment means and the second attachment means being neither conjunctive nor repulsive to second attachment means when juxtaposed on faces of adjacent blocks, and a plurality of representation symbols on each block, the representation symbols and the attachment means being organized in a predetermined arrangement, and a base having attachment means for individually holding the first attachment means while not repelling the second attachment means, whereby rows of blocks with interengaged first and second attachment means are arranged on the base with the base attachment means holding the rows by engaging with the first attachment means on individual blocks.
Claim 3
Dependent Claim
53 words
The comprehension enrichment apparatus of claim 1 wherein the first attachment means comprises a convex spheroidal lug positioned in a center of a face, and wherein the second attachment means comprises a complementary concave spheroidal depression in a center of a face, and wherein the base attachment means comprise uniform concave circular depressions.
Claim 4
Dependent Claim
58 words
The comprehension enrichment apparatus of claim 1 wherein the blocks are arranged in square arrays having interengaging first and second attachment means on juxtaposed faces and wherein the blocks are organized with equal numbers of blocks in sides of the array and wherein blocks are positioned in the array according to predetermined numerical limitations of the representation symbols.
Claim 5
Dependent Claim
27 words
The comprehension enrichment apparatus of claim 3 wherein the blocks are arranged in horizontal arrays with single faces of the blocks revealing representation symbols in the array.
Claim 6
Dependent Claim
25 words
The comprehension enrichment apparatus of claim 3 wherein the blocks are arranged in vertical array with representation symbols exposed on opposite sides of the array.
Claim 7
Dependent Claim
21 words
The apparatus of claim 3 wherein the blocks are disposed on the base having spaced depressions arranged rectilinearly in square configuration.
Claim 8
Dependent Claim
32 words
The apparatus of claim 3 wherein the blocks are arranged so that first and second attachment means are juxtaposed and so that second and second attachment means on different blocks are juxtaposed.
