American snowboard sensation Chloe Kim produced a brilliant performance to take gold in the women's halfpipe.
The 17-year-old won with a score of 98.25 on her final run with China's Jiayu Liu taking silver and United States' Arielle Gold winning bronze.
Kim had already secured gold with her first run score but improved to win by eight-and-a-half points.
She is one of the stars of the Games and a favourite with the home fans due to her South Korean parents.
"It means a lot just being able to do it where my family is from," Kim said after her win which was watched by the biggest crowd so far at Pyeongchang's Phoenix Snow Park.
"There was a lot of pressure, but I'm happy I was able to do it here and do it for the fans and the family.
"I'm so happy I was able to land and being here is so exciting, this has been a dream of mine."
