Snowboard halfpipe is a snowboard competition in which the competitors starts individually from the top of a halfpipe. The half-pipe is a semi-circular ditch or purpose built ramp (that is usually on a downward slope), between 8 and 22 feet (6.7 m) deep. Competitors perform tricks while going from one side to the other and while in the air above the sides of the pipe. The halfpipe discipline is scored by judges with one overall impression score based on the following criteria: execution of tricks, variety of tricks, difficulty, pipe use, and amplitude.
Major multi-sport competitions
