44 tiles, each having three coloured spots are shuffled and placed face down. There are four different colours of spots. Two tiles of each colour are 'triples' and have three spots the same. The remaining tiles are all unique, and each colour has exactly 33 spots. Each player picks three tiles and a player is chosen to start the game. Play is simple, place a tile to the table on either side of an already placed tile. Once a row of 11 tiles is formed, a new row must be started. The player then draws to refill his hand to three. Whenever three or more spots of a colour exist, a player scores one point for each spot, diagonal lines count double. A player who plays a 'triple' automatically gains at least three points. The game ends when four rows have been completed... all 44 tiles are played. The player who scored the highest total wins. In the German/Dutch/French/Nordic versions of Domingo (published by Ravensburger), there are 48 tiles, but the game otherwise appears to be identical.
