In Animal Duet, players aim to collect pairs of cards. The game uses a mechanic where players choose to either reveal a card from the deck into a row and then take another turn, or collect all revealed cards. If a revealed card matches a card already in the row, a player busts and takes only the newest revealed card, ending their turn.
In Animal Duet, all face cards and jokers are treated as jokers and when taking cards from the row, if there is a joker present, the player takes all cards on either side of the joker and the joker itself (rather than the entire row.)
