In Cubu, each player starts with a hand of seven cards, with each card showing a combination of different-colored boxes and a number, or a special action. Each turn you can either play an action card by giving it to another player, who must do what the action says, or play any number of Cubu cards, as long as they continue in the sequence begun. Sequences grow by color or location, and progress either up or down – but must go in the same direction in a single turn. Box number is determined by counting from the inside out. The first player to empty his hand wins the round and scores points for each card left in opponents' hands: 5 points per Cubu card, and 10 points per action card. The first player to reach 100 points wins.
