Have you ever played Telephone, also known as Gossip, Grapvine, Broken Telephone, or Chinese Whispers? Telesketch is played much the same way, but instead of whispering you draw pictures!
Write a sentence and send it to all your friends to draw. They send their drawings to all of their friends to caption. And so on and so forth.
Telesketch is OpenFeint Enabled. Use OpenFeint to challenge your friends to create drawings or captions. Track high scores and earn achievements.
