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.
