The rules are pretty simple:

1.   Each thrower will have 3 throws, taken in turn with the others within their allocated group.

2.   The thrower must use one of the phones provided for them.

3.   The thrower can use any method of throwing.

4.   The throw must land within the side-lines marked out on the grass.

5.  If you step over the line at the end of the runway, the throw will not stand.

7.   The length of throw is judged from where the phone first hits the ground, not from where it ends up.

8.   The stewards decisions are final!
