Abstract
A set of hexagonal or triangular pieces adapted to the playing of variants of the game of Go on a plain unmarked surface, by laying pieces down contiguously. Each piece has means for picking it up when it is surrounded by other pieces, as by having a central hole into which the stick-like handle may be temporarily inserted. Dual pieces, each shaped as two single pieces of opposite colors joined together along a common side, are also provided.
