The title Pájaros en el Alambre means Birds on the Wire. The game consists of cards with ten different birds, all armed with guns.
At the beginning of the game, a wire with 10 different birds is laid out on the table. During their turn, a player may choose to either exchange a card from their hand with a card on the wire; or move a card on the wire to the left or right (as stated on the card). Each kind of bird has a requirement as to how many of them must be adjacent to another to form a set. When a player creates a set, they take out those birds as score cards and replace them with cards from the pile. When the wire cannot be refilled, the player with most points is the winner.
