Hong, named after a two-headed dragon in Chinese mythology, is a tile-laying game of asymmetrical goals for two players, invented in December 2012 by Néstor Romeral Andrés. Two players – MORE and LESS – share a common pool of identical squared pieces depicting two dragon heads and one dragon segment. A hong is a straight line of one or more segments with a dragon head on each end. The MORE player must create as many hongs as possible, while the LESS player must prevent that many hongs from being created.

Note that open-ended dragons or pairs of heads with no segments in between them are not hongs.
