Sack of Lies, a card game for liars, the box cover shows a wolf, fox, vulture and cobra competing for the pot! You must clear your hand of 10 cards, by placing successive cards face down on the deck, bluffing as necessary. So the deck is started by a player laying 1s, the next player lays 2s, one by one and so on. At some point, your bluff is called. If you were false, draw more cards. If you were true, your opponent draws. There are action cards, including a sack of lies which has no value and so you must lie when playing it. - BoardGameGeek
