This game is the Spanish equivalent of Oh Hell!. There is a difference in the play of the cards: in La Podrida players who cannot follow suit are obliged to play a trump. The name of the game means "putrid" or "rotten". It refers to the strategy of spoiling other players' contracts by giving them too many or too few tricks.
Rules in Spanish of an Argentinean version can be found on this archive copy of the page of the Federación Internacional de Podrida.
Rules for a Mexican variant can be found on Gonzalo Mena-Mendoza's page Juego de las Bazas.
Javier Garcia has written apps for La Podrida and the related game La Pocha for iPhone.
