Chromino is a 2001 board game designed by Louis Abraham, for 2 to 7 players. The game is similar to the classic game of dominoes, but uses colours instead of numbers. Five colours are used: red, blue, purple, yellow and green. Each Chromino piece contains three coloured squares, and all 75 distinct combinations of colours are used. There are also five "wild card" pieces, with a yin-yang symbol in the middle, where the middle square may be used as any colour.
Each piece has eight square edges. At least two edges must touch a piece already on the board, and squares of different colours may not touch each other. The game begins with a randomly chosen piece placed on the board. On their turn, each player places a piece on the board. If they cannot place a piece, they must take a new one. The first player to run out of pieces wins.
