Abstract
Abstract A kit-type game or amusement device having a foundation board, building blocks and connector rods. The board and blocks have holes formed therein adapted to frictionally receive the rods, and the spacing between adjacent holes on both are related. The relationship makes possible the construction of an almost limitless variety of free-form structures.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
116 words
A construction amusement device of the character described comprising: a foundation board having a plurality of holes formed therein, said holes being arranged in rows and columns with unit spacing between adjacent holes; a plurality of blocks having one or more holes formed in at least two sides thereof, adjacent holes on any one of said sides being spaced apart one-half unit or a whole number multiple of said unit; and a plurality of connector rods each adapted to be received at either end thereof in any of said holes, whereby said blocks with a plurality of holes in their sides may be connected with two or more rods to the board or to another block.
Claim 2
Dependent Claim
116 words
A construction amusement device of the character described comprising: a foundation board having a plurality of holes formed therein, said holes being arranged in rows and columns with unit spacing between adjacent holes; a plurality of blocks having one or more holes formed in at least two sides thereof, adjacent holes on any one of said sides being spaced apart one-half unit or a whole number multiple of said unit; and a plurality of connector rods each adapted to be received at either end thereof in any of said holes, whereby said blocks with a plurality of holes in their sides may be connected with two or more rods to the board or to another block.
Claim 3
Dependent Claim
71 words
The construction amusement device of claim 1 and comprising further additional holes formed in said board and arranged in a second set of rows and columns with unit spacing between adjacent holes, the holes of said second set of rows and columns being positioned so that the spacing between each of them and an adjacent hole in the first set of rows and columns is equal to one of said units.
