Object of the game: Avoid getting caught with the Old Nag at the end of the game.
Dealer shuffles the cards and deals out the entire deck one card at a time to each player. All the cards in the deck have a match BUT the Old Nag. Players place matching cards on the table. Next, the player to the left draws a single card from the dealer's hand. If there's a match, the player puts the pair in the table. No match, the offers her hand to the next person on the left. Plays continue until there is one card left in one hand. That player has the Old Nag which has no match and loses the game. But the player holding the Old Nag gets to be the dealer the next round.
