Snowboarder Jamie Nicholls was the only Brition to make it straight through to the slopestyle finals in the first day of action in Sochi.
Fellow Brits Billy Morgan, Jenny Jones and Aimee Fuller will ride again in the semi-final to compete for a place in the first ever Olympic slopestyle final..
The 20-year-old Nicholls qualified fourth from his heat on the opening afternoon of competition.
"I can't believe what I've done," said Nicholls adding: ""My dream was to get to the final, I'm so happy to make it in my first Olympics."
The Rosa Khutor Extreme Park, subject of much controversy leading up to the games, looked in pretty good shape with most riders navigating the tricky course well.
The men came out of the gates first, led by Morgan, who produced some huge tricks and looked set for a place in the final.
The women remained a little more conservative, getting a feel for the course and posting safe but decent times.
The best scores of the day came from Anna Gasser of Austria and American favourite Jamie Anderson in the women's qualifiers while reigning Olympic halfpipe gold medallist Torah Bright of Australia qualified in second from the first heat.
The women's final takes place on Sunday while Jones and Fuller will look to make it into the top four of their prior semi-final in order to join the current eight finalists
Meanwhile, it remained close in the men's qualifiers with Maxence Parrot of Canada coming out on top while Morgan has a second chance to fight for a place in Saturday's final.
