Bah! Humbug! and the 12 Games of Christmas is a collection of 13 original holiday card games by 13 designers, reimplementing and expanding Bah! Humbug!: A Twelve Days of Christmas Bluffing Game by Emily Willix into a versatile box of games for 1-12 players. At the heart of the collection is a 78-card "12 days of Christmas" deck featuring Victorian-inspired animal art. The box also contains 34 wooden pieces, a detailed rulebook, and several additional card sets which may be combined with the base deck in various ways.
