IDEADLE

Ideadle is a free daily design game by Design Board Show, a London street show where strangers sketch a fix on a whiteboard and pitch it. Every day everyone gets the same everyday problem: 15 seconds to think, 1 minute to sketch a fix, 110 seconds to pitch it. Then Marky, the red marker, scores your idea on Fix, Sell and Build, tells you what to do better next time, and shows how you rank against everyone else today. There's no single right answer, so the more creative and convincing your idea, the higher you go. No login, one ranked try a day.
