At the start of the game each player has a hand of 14 tiles. The object is, by drawing and discarding tiles, to form sets of equal numbered tiles, and runs of consecutive tiles of the same color. These groups of the tiles are moved from the hand to the table. Additionally it is possible to add tiles one-by-one to the existing series on the table. The less tiles will remain on the hand at the end the better.
