Aha! the image is in layers. here is what I got!
TUBES!! The game is going to be a seris of tubes!
My point: there is no way anyone is going to figure out this clue, all we got is a black 5, a diamond plate circle, and some crazy blue background. Its not much to go on. I dont mean stop trying, but some of these sugesstions are getting ridiculous. Water? there is no way it would be allowed on the field. there is too many room for things to go wrong with water near elecrical equipment.
