The Zynga Lotto is a subdomain of the Zynga.com website. This is the only way to get a Red Goat, Red Sheep, Red Cow or Red Horse. To play this game, you must sign up here (The Lottery is over) for the Zynga Lotto account. You then will receive an email to confirm your email address & account. Users are then given 1 free play. Essentially you scratch 3 of 9 of the squares on the card. If a star with a number pops up, you win the prize associated with that number.
