Ready, set, go! At the ring of the bell, everyone plays at once. Players trade cards from their hands as they try to collect 9 of the same type of commodity. Cards feature fun and colorful illustrations of commodities such as sugar, coffee, corn, oil, and gold. Without revealing their hand, players hold up the cards and call out how many there are that they want to trade. They can trade with anyone holding up the same number of cards. Got 9 of a kind? Ring the bell to win the round. The first player to win three rounds wins the game.
