BLUE is a game from the RED, BLUE, GreenGreenerGreenest trilogy. BLUE is a three-coloured tile-laying game for three players. It is a crossbreed of the games RED and Hong, by the same designer. The three colours in the game are white, gray, and blue, and each player will be a different colour. The tiles have the same design as in Hong, but combining those 3 colours in a black background. So there are 3 types of tiles in total. A row is a straight line of one or more aligned segments of the same colour with a semicircle of that colour on each end. A spot is a circle made of 2 semicircles of the same colour with no segments in between. Players place tiles on the table trying to create as many rows and spots of their colour as possible.
