Each in turn, players draw a Cow card that can feature 1, 2, or 3 animals. They must then choose a row to place the card, always adding at least one new type of cow to that row (if all cow types are already present in every row, the player may choose any row to place their card). When a player places the 6th different cow on a row, they can collect all the cards from that row. When the draw pile is exhausted, the player who has collected the most cards is declared the winner!
