From the Publisher:

This is a new 3-in-1 card game deck. Old Bill is a quick little bluffing game set in the universe of Caper. You’ll work to make trades with a mixture of open and hidden information. Be sure to bring your best negotiating face to the table. You'll need it to squeeze out the points in this game. You can also pull this box out for a classic game of Old Maid (with ole' Bill) or Memory with family.
