White earned 97.75 points in his last run of three to win the 100th Winter Olympic gold medal for the United States, beating Ayumu Hirano of Japan to the second place with 95.25. Scotty James of Australia took the bronze with 92.00, reports Xinhua news agency.
White said: "I knew I did a great ride and I was proud of that and I could walk away with my head high, but when they announced my score and I'd won, it crippled me."
"Honestly it's one of the most challenging runs I've ever done. Three gold medals. My fourth Olympics. Thank you, I'm feeling blessed," White said.
The four-time Olympian injured his wrist in a fall in slopestyle and fell on his final run in the halfpipe, finishing fourth in the 2014 Sochi Olympics.
"I just have to thank my team. They were always there to support me and reassure me that what we're doing is on the right track and they believed in me. That really helped me." White added.
