Snowboard events come in two kinds. Judged events — slopestyle, halfpipe, big air — are scored by a panel, often out of 100, and in many formats only a rider’s best run counts. Racing events — boardercross and parallel slalom — are won on the course, with boardercross heats of four or six where the top riders move on.
A season series turns each event’s places into points and adds them up, usually with separate tables for each discipline and category.
