There are three different types of event in the snowboarding - half-pipe, parallel slalom and cross.
The cross is a relatively new event in the Games and can look a bit strange.
Riders compete over a course of jumps, bumps and turns to get into the final 32. then they go off in groups of four until there are only four left, when the medals are won and lost.
The half-pipe is more the kind of boarding event we're used to, where riders launch into a big tube cut into the snow and perform tricks after launching themselves into the air from it.
Loud music is played to get the crowd going, and five judges decide who's scored the most points.
Parallel slalom sees two riders at a time on the mountain, racing on courses which run parallel to each other, while skiing through a series of gates.
Each rider has a go from each of the two starting points. The one with the quickest time wins and gets through to the next round, until a final decides the Olympic champion.
