This game is best described as a 'progressive Concentration'.The deck consists of 4 animal types goat, donkey, lamb, and pig. Players take turns revealing cards from the deck. After being revealed the card is placed face down. If a player after their turn believes they can find a set of four matching animals they may try to do so. If successful the animals are collected and scored, otherwise the cards remain face up - aiding the other players. - BoardGameGeek
