For the details, the rules, the winner selection and the prize, go to the original/Day 1 contest post. The forms for Days 1, 2, 3, 4, 5 and 6 are now closed, so please do not enter any answers there, as they will be disqualified anyway.
I would highly recommend that you read everything in the Day 1 post if you haven't already, before submitting an answer. Also, if you are a new follower (HI!), you might want to get all the previous clues by going to the post of that particular day (:
