Cards Against Humanity is a game similar to Apples to Apples but made for adults. It has more sexual innuendos, as well as more adult humor.
The original Cards Against Humanity game has 550 cards; 460 are white cards, while the other 90 are black cards. The goal of the game is to win black cards. In each round, one person draws a black card. Other players anonymously submit a white card. The person who drew the black card reads the white cards aloud and then chooses the pairing that she thinks is the funniest of the group. The person who submitted that white card wins the black card for the round.
