Cards Against Humanity is a party game for adults in which players create outrageous, dark, and often hilarious combinations using question and answer cards. One player reads a black card containing a question or sentence with a blank space, while the other players submit their funniest or most shocking white card to complete it. The reader then chooses the answer they find most entertaining.

The game is known for its crude humor, satire, and unpredictable combinations, making it popular for parties and game nights among adults. It is easy to learn, quick to play, and focuses more on creativity and humor than strategy.

Cards Against Humanity is designed for groups and works best with players who enjoy edgy comedy and improvisation. The game has also inspired many themed expansions and special editions that add new cards and jokes to keep gameplay fresh.
