The board consists of five columns of eight colored marbles, the colors being arranged randomly in each game. On each turn a player takes any number of marbles, but marbles may only be removed from the top of a column and all marbles taken on a single turn must be the same color. The object is to amass the most marbles.In an optional variation (only in Take All, the Orda edition) there is a single black marble which is worth 5 ordinary marbles. - BoardGameGeek
