## Abstract

A game or puzzle including a plurality of polyomino assembly pieces and a support base. The support base may comprise a polygonal bottom member, one or more towers, and side walls. The support base aids the user in visualizing the shape of the puzzle to be assembled and provides support to the assembly pieces during puzzle assembly.

## Claims

### Claim 1

An assembly puzzle comprising:
a three-dimensional, symmetrical figure consisting of interfitting assembly pieces and a support base;
the support base comprising a shape equivalent to:
a flat, horizontally-oriented, polygonal bottom member possessing an upper surface and edges;
the upper surface being divisible into a whole number of identically-sized, edge-connected squares;
the upper surface having an area;
at least one vertical tower having a height;
the tower being facially attached to at least one upper surface square;
at least four vertically-oriented side walls having top, bottom, and side edges;
the side edges of adjacent side walls contacting one another;
the bottom edges of the side walls contacting the bottom member;
the side walls being divisible into a whole number of identically-sized, edge-connected squares;
the assembly pieces and vertical tower having a shape equivalent to a whole number of identically-sized, facially-connected cubes;
the symmetrical figure being at least two cubes in thickness;
the volume of the symmetrical figure being defined by the area of the upper surface multiplied by the height of the side walls; and
the shape of the symmetrical figure conforming to the shape of the support base and the height of the side walls.

### Claim 2 (depends on 1)

The puzzle of claim 1 wherein the volume of the symmetrical figure, minus the volume occupied by the tower, is sixty cubes.

### Claim 3 (depends on 2)

The puzzle of claim 2 wherein the assembly pieces have a shape equivalent to five facially connected cubes whose centers all lie in a single plane, the pieces being:
one piece having a shape equivalent to five adjacent cubes aligned in a row;
one piece having a shape equivalent to four cubes aligned in a row and a fifth cube connected to a side of an end cube in the row and the fifth cube being out of alignment with respect to the row;
one piece having a shape equivalent to four cubes in a row and a fifth cube connected to a side of an intermediate cube in the row;
one piece having a Z shape;
one piece having an S shape;
one piece having a V shape;
one piece having a T shape;
one piece having a W shape;
one piece having a shape equivalent to 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 the fourth cube;
one piece having a shape equivalent to four cubes that form a square and a fifth connected to one side of the four cube square;
one piece having a cross shape;
one piece having a U shape.

### Claim 4 (depends on 2)

The puzzle of claim 2 further comprising colored assembly pieces.
