In You Lying Sack, you want to be the final player in the game, with everyone else having been removed because they were terrible liars.

Each player starts the game with two "bad things", these bad things being made of foam. A sack is filled with made more bad things, along with one good thing, which is made of hard rubber.

Whatever you draw, hold your clenched fist (or fists) out to the player on your left and say, "My hand is full of bad things. Will you take them?" If they decline, ask the next player. If everyone declines, then you keep any bad things in your hands; if you had the good thing, however, give away to other players as bad things from your pile as the number shown on the die, then return the good thing to the sack.

If you ever have at least ten bad things in your pile, you're eliminated from the game. When only one player remains in the game, they win.
