A family-friendly iOS game. It is whisper down the lane with a twist.
Even though it is so simple, it is guaranteed fun. The first person makes up a word and passes it to another player, who then has to illustrate the word on a piece of paper. He passes the drawing to the next player who guesses the pictured word, and so on.
Once you participated in a game, you're able to see all future drawings and guesses in that game. You can send messages around praising drawings or making fun of bad ones.
