The halfpipe is almost 200 yards long, it is 65 feet wide and the high walls are 23 feet.

During the competition the halfpipe competitors go back and forth across the pipe doing a series of tricks. Shaun White's McTwist is 3 ½ rotations in the air and the McTwist adds two twists.

There are 6 judges who score on: Height in the air, difficulty, execution variety and the use of new and uncommon tricks.

The judges can take away points for small mistakes like flat landings or deck landings.

A medium mistake would be a full stop or dragging their hand on the snow. A major mistake would be a complete bail and that could knock off 25 points.

Each judge can give a maximum of 100 points per run the scores are averaged together and the highest score wins gold.

The Americans have won 19 of the 60 medals at the Olympics and those are your rules of the game.
