That's good. It's a sport (game, whatever you wanna call it) some people play here. The basic principle of the game is to get the oval shaped ball from one side of the field to the other to score points. You can also kick it between the goal posts but you don't get quite as many points if you were to run it into the endzone/scoring area. You also have so many attempts to get the ball ten yards. If you make it over the ten yards within four attemps you get four more in that new ten yard section.
It's confusing when you read it and I think more enjoyable when you watch a game.
