I'm watching Aussie Rules Football right now, and I have no idea what is going on.
Basic rundown of the rules (I'm not Australian but understand the basics):
1) You can run with the ball, but have to dribble it off the ground kinda like in basketball every few steps or so (don't understand specifics).
2) You can move the ball by either punching it with a closed fist, or kicking it (kicks are usually punts, but you can kick at a loose ball too).
3) If you get tackled, you have to release the ball and the tackler has to release the tackled player (similar to rugby here, but there's no "ruck" that forms afterwards - in fact "ruck" refers to something else in Australian football, it's a free-for-all dogpile).
4) If you catch a kicked ball that travels a certain distance (10 meters I think) before it hits the ground, you get a free kick from where you caught it. The ball could have been kicked by either a teammate or an opponent, hence tactics usually revolve around trying to get "marks" whether defensively or offensively.
5) There are four posts at either end of the field (and extend upwards indefinitely like goal posts in football). Punching the ball is legal in general play, but you may only score by kicking the ball. If you kick it "cleanly" (untouched by any player on either team) through the middle posts, it's a "goal" and worth 6 points. If you kick it through one of the outer posts, it's a "behind" and worth 1 point. A deflected (by either team) kick that goes through either set of posts (or is sent through either set of posts through the defending team) is also only worth 1 point. A kick that hits one of the inner posts is not considered a goal, and is worth 1 point even if it it caroms through the inner posts. A kick that hits one of the outer posts is considered to have gone out of bounds (even if it caroms through anyway).
6) Illegal play is generally penalized by a free kick to the non-offending team, such as physically interfering with attempting to catch a kicked ball, similar to pass interference in football.
