Freestyle skiing includes newer events such as Slopestyle and Halfpipe, as well as the long-established Moguls and Aerials. These events differ from Alpine racing as there is a judging element which awards points for acrobatic tricks performed, based on style and technical difficulty. The outlier in the Freestyle category is Ski Cross which is a head-to-head race down a course which includes jumps and banked turns, the winner being the skier who crosses the line first.
Riders perform mid-air manoeuvres that are made up of multiple rotations by launching themselves up a 2-4m jump, propelling them up to 6m in to the air. Riders choose from one of three kickers to launch from - the first is used for single-turn backwards (more commonly referred to as a backflip), the second jump for double-backward turns and the third for triple-backwards turns.
Competitors then chose how many spins they mix in with the backward turns - this defines the difficulty of the trick, which is then given a numerical value. While performing their chosen trick points are awarded by judges for various criteria: air performance, form and handing. These scores are then multiplied by the difficulty to provide the final score.
