You Lying Sack is a first-of-its kind collaboration with Penn Jillette of the legendary magic-duo Penn & Teller.

To play, reach into the Lying Sack and secretly grab Good or Bad Things, then go around the table and offer your closed fist. You will need to bluff, double-bluff, and do whatever 8 overlapping bluffs is called to outsmart your opponents. The odds change each turn, so your strategy should too. Will you outsmart your opponents? Or will you get caught?
