Pairs is a "New Classic Pub Game" by James Ernest and Paul Peterson, who also brought you Unexploded Cow. It's an extremely simple press-your-luck game featuring a deck of number cards (1 x 1, 2 x 2, 3 x 3, and so on, up to 10 x 10). There is only one loser, and the object is not to score points by colelcting a pair.

From Pat Rothfuss' child-like book that's very much NOT for children, comes Nate Taylor's "Princess and Mr. Whiffle" Pairs deck, a macabre and delightful collection of dismembered stuffed animals and other nightmare creatures. This deck is based on a series of books by Rothfuss, beginning with the Princess and Mr. Whiffle. They are charming for grown-ups, but, despite their fairy-tale look, they might or might not be suitable for your child.

The Princess and Mr. Whiffle deck will also come with a game called Stacks, which has several variations of its own.
