Abstract: The present invention is directed to a three-dimensional game board that can be built by a player. The three-dimensional game board may include a plurality of building components having at least one integrally formed hexagonal element, wherein adjacent hexagonal elements share a common side. The hexagonal elements may include a raised hexagonal surface having an edge extending upwardly from a top surface of each hexagonal element. The edges of the hexagonal surfaces of adjacent hexagonal elements may define a channel therebetween. A sidewall may extend downwardly from a peripheral edge and may be defined by the integrally formed hexagonal elements. The sidewall may be configured to be received into the channels formed by the hexagonal surfaces of a building component disposed below. Portions of the sidewall may engage corresponding hexagonal surfaces of the building component disposed below to maintain the building components in substantial vertical alignment.
