Eton Field Game

For thoughtful child sponsors
The Field Game is one of Eton’s two brands of football, the other being the famous Eton Wall Game. It is like soccer in some ways — the ball is round and you are not allowed to pick it up — but the off-side rules are more in keeping with rugby and there is also a small scrum or ‘bully’. You score goals much as in soccer (although there is no goal-keeper), and you can also score ‘rouges’ (which are something like tries) and attempt to convert them.

It is the only game at Eton that virtually every boy plays, at least for his first three years in the School, and it occupies prime position in the games programme throughout the Lent Half. The boys representing J M Noakes' House have arguably been the most dominant force in recent years.
