The game is simple to play, and based on the old spot-the-ball competition. Below is a picture taken at my wedding. There were five hats in the picture, but I blotted them out. All you have to do is, using your skill and judgment, say where the hats are. Then, you send me an email with your answers, and I reply to tell you how many you got correct.
If I'm bored / keen I'll post the names of the people who sent the best and worst entries (but not their email addresses - I hate spam, particularly being vegetarian).
To help you, there is a picture taken before the key one, and also one after. The picture taken beforehand gives an important piece of information: the names of the hat wearers. Your email should give a co-ordinate for each of the names, corresponding to where you think that person's hat is.
Send me an email with where you think they are. Don't forget: 5 names, each with a co-ordinate. The top-most row and left-most column of the grid are valid areas, so the hats might be there...
