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.

The 2023 boxed edition includes rules for these original games:

Animal Menagerie (2 players) a card-drafting and set collection game by Emily Willix & Clark Willix
Christmas Parade (2 players) a card manipulation game by Felix Falk
Deckbuild the Halls (3-4 players) a trick-taking and deckbuilding game by Duncan Hecht

Bah! Humbug! and the 12 Games of Christmas is also a growing online collection of games and variations—including solo games, party games, puzzles, Victorian parlour games, and original submissions—which can all be played using the cards and components included in the box. There is a BGG thread for contributing new and existing compatible games, and Small Furry Games also plans to release new original games each Christmas season.
