Play set for game of skill with pieces formed by cubes

Claim 1

A play set consisting of: eleven fixed configuration pieces (A-N) each made up of five rigidly connected identical cubes lying in a common plane with common top and bottom surfaces, said eleven fixed configuration pieces comprising, one piece (A) having four cubes in a row and a fifth cube connected to a side of an end cube in the row and said fifth cube being out of alignment with respect to said row, one piece (B) having four cubes in a row and a fifth cube connected to a side of an intermediate cube in the row, one V-shaped piece (C), one piece (D) having four cubes connected to form a square and a fifth cube connected to a side of one of said cubes that form a square, one U-shaped piece (E), one S-shaped piece (F), one piece (G) having three cubes in a row with a fourth cube connected to a side of an end cube in the row and a fifth cube connected to an opposite side of an opposite end cube in the row which is opposite from said fourth cube and said fourth and fifth cubes being out of alignment with respect to said row, one piece (H) having three cubes in a row with a fourth cube connected to a side of an intermediate cube in the row and a fifth cube connected to an opposite side of an end cube in the row which is opposite from said fourth cube, one T-shaped piece, (L), one cross-shaped piece (M), and one W-shaped piece (N); one fixed configuration piece having four identical fixedly connected together cubes lying in a common plane with common top and bottom surfaces and forming a square; and one variable configuration piece comprising five identical cubes and connecting means connecting said five identical cubes together for permitting varied configurations for said variable configuration piece, each of said five identical cubes of said variable configuration piece always having common top and bottom surfaces and lying in a common plane, all cubes of each variable configuration piece comprising a cube having a central slot in one end thereof extending from said bottom to said top surface and a central hole extending through an opposite end thereof and into communication with said slot, said means for connecting said cubes of said variable configuration piece comprising an elastic band extending through each hole of each cube and through each slot of each cube; said cubes of said fixed and variable configuration pieces all having identical outside dimensions so that said fixed and variable configuration pieces can be mated together to form a variety of combined configurations.
