Snowboard is a sport that uses a board attached to rider's feet to speed down a slope. Snowboard was first developed as a sport in the United States in the 1960s. It was officially adopted as a formal discipline at the Nagano 1998 Olympic Winter Games. Snowboard at the Olympic Games presents a total of 10 individual events:
Parallel Giant Slalom(men and women), Halfpipe(men and women), Snowboard Cross(men and women), Big Air(men and women; newly added for PyeongChang2018) and Slopestyle(men and women)
The SBS is held on a course organized with the various objects such as rails, tables, boxes, walls, and jump pads. The athletes can select the objects they want to perform with.
The 6 judges mark the overall performance score according to the height, rotations, techniques, and the degree of difficulty with the perfect score being 100 points. It is an event in which the ranking is decided with the average of the scores of 4 judges after disregarding the highest and the lowest scores. The athletes perform twice and the ranking is decided with the higher score.
The Olympics standard course is as the following: Minimum elevation difference 150m, the slope of the slant is 12 degrees or higher on average, minimum width 30m, with a minimum of 6 or more sections (the objects + the jump), and 3 or more jumping pads.
