From Briggsy Interactive:
In Greedy Piggy two players reach 100 points. Players take turns rolling two dice, if neither of the dice are a 1, their sum is added to the turn total. If a single 1 is rolled, the player scores nothing and the turn ends. If two 1s are rolled, the player's entire score is lost, and the turn ends. Greedy Piggy lets you play the great pig folk game anywhere.
