How park and pipe events work

Shown with halfpipe, slopestyle and big air, for snowboarders and freeskiers.

1. Three to seven judges score each run from 0 to 100, on an overall impression: execution, difficulty, amplitude (height), variety and progression.
2. In halfpipe and slopestyle each rider has two or more runs, and usually the best one counts.
3. In big air each rider gets three jumps and the two best scores are added, but only if the tricks are different.
4. Riders qualify through heats to a final, and the highest score in the final wins.

Cross

The other main format is snowboard cross and ski cross: four or six riders race together over jumps and banks, and the first across the line go through.
