About the article "Snowboarding", section "Slopestyle".

Candidate passages:
Snowboard has vertical drops between and for both men's and women's races with the course being run over a distance of to .
The course has alternating gates.
The sport is only open to standing competitors. 
Jibbing is snowboard speak for doing skateboarding-inspired tricks, like sliding on obstacles—the first mention of it came during a 1989 interview with pro snowboarder Nick Perata.
Conversations to create an invite-only event that would elevate the level of contemporary snowboarding with custom courses and obstacles first came to Nixon via Jeremy Jones, JP Walker, and Dave Downing in the late 90s.
From those early brainstorming sessions, the Nixon JibFest was born.
With the expert help of Snow Park Technologies’ Chris “Gunny” Gunnarson, the Nixon JibFest has seen its fair share of custom, one-of-a-kind and often feared features, including some of the more known features, as seen in Mack Dawg Productions' Stand & Deliver, Decade and The JibFest Documentary films.
In 2011—after an eight-year hiatus—the Nixon JibFest returned as the premier invite-only snowboarding event.
The revitalized contest brought with it a new custom course, a new crop of invited riders and a new jibbers playground.
All was documented for an web series that launched on vice.com 
Snowboard racing is a form of snowboarding where competitors attempt to obtain the fastest time down a course.
Snowboard racing can be done against the clock, or by two or more competitors racing in a head-to-head format.
The current Olympic snowboarding racing events are parallel giant slalom, parallel slalom and snowboard cross. 
In addition to the usual gameplay of a snowboarding game, "Snowboard Kids" adds "Shots" (special weapons used to attack players) and items which can help the player, hinder other players, or both.
The game has nine main courses.
Although some of the courses are snowy mountains, many are courses that would be unorthodox for snowboarding in the real world.
Such courses include an amusement park, a desert, a vast valley, a dark highway, and a Japanese village during the cherry blossom festival.
Each track has a unique shape, containing various obstacles, hazards, and short-cuts.
There were several game mechanics that were unique to "Snowboard Kids" from other snowboard games and racing games at the time.
One was the addition of the second item slot, allowing each player to carry a shooting item and support item (such as a rock, or invisibility) at the same time.
Unlike many other 'Kart style' racing games, players were required to pay 100 gold in order to collect an item during a race.
Gold could be obtained either through performing tricks or collecting coins scattered across the course.
All courses also required players to race down the hill for multiple laps.
Once a player had reached the bottom of the hill, he or she would need to pass through the lift gate to be transported back to the top of the hill, and could not be attacked by other players in this transition.
