Unlur, the winner of the 2002 Unequal Forces Game Design Competition (sponsored by About Board Games, Abstract Games Magazine, and the Strategy Gaming Society), is an abstract strategy game played on a hexagon-shaped tessellation of hexagons with eight hexagons on each side.
Unlur is also a game of unequal forces -- each player has a different objective. Black wins if 3 non-adjacent sides are connected, white if 2 opposite sides are. Thus black's goal is harder; to compensate, black will begin with some pieces already on the board. Initially, players do not yet have assigned colors; they take turns each placing a black piece on an empty hex. Either player may instead pass to become black (when they feel black has enough pieces on the board); the other player becomes white and places a white piece, and they continue alternating turns placing their own color. Black wins by forming a Y (connecting 3 non-adjacent sides) but loses by connecting 2 opposite sides without a Y. Likewise white wins by connecting 2 opposite sides but loses by forming a Y without connecting 2 opposite sides.
