Dragons (2009)

Dragons is a tile placement game in which two players strive to complete sinuous loops of their colour.

Two players, Green and Red, share a common pool of 50 hexagonal dragon tiles. Each tile shows shoulders on the front and tails on the back in both players' colours.

The opening player places a tile of their choice in the centre of the playing area. Players then take turns adding a tile of their choice adjacent to at least one existing tile, such that edge colours always match.
