No one wants cows buzzing with flies! In the card game "Cows", some cards are buzzing with flies and some are not. Try to add a cow card from your hand to the herd. If you don't have a suitable card, you'll have to take the entire herd into your barn, along with the flies... Be careful not to collect too many flies, each fly will add a bad point to your score! The player who collects the fewest flies is the winner!
