Animated skill-based competition

I want to launch a competition that uses a basic game to engage with users. We are launching a TV ad and want to get people excited about. I work for a UK [login to view URL] and we want to create a viral, online game along these lines: The graphic is a house, which when someone's mouse hovvers over parts of it, triggers a sounds. So people can play the house and make music. So point at the window and the sounds of it closing is played. The competition is this: after opening the game, the player is invited to listen to an audio clip of our ad (which includes distinctive house sounds) and then play the noises on the house in the right order. If they complete this correctly then a redirect takes them to a registration page on our site, where they input their email to enter a prize draw. if they don't then they are invited to try again. This game would be hosted off our site on a specific URL. We will organise this. Many thanks.
