Both the men and women's Great Britain curling teams will have the chance to compete for medals after qualifying for the semi-finals.
The men's team had a deeply impressive round robin stage and had already assured their semi-final spot ahead of their 5-2 win over Canada on Thursday.
Beth Muirhead's women's team had to endure far more tension though with them heading into their final match against ROC relying on other results.
They won their match 9-4 after nine ends, but needed at least two of the other three results to go in their favour.
Thankfully for them, Switzerland beat Japan and Sweden beat South Korea, meaning it was Canada who missed out on a medal chance.
Britain will now play Sweden in the last four, with the winner guaranteed at least a silver medal.
"We had to win that game today and that was the first thing we went out there to do," Muirhead told BBC Sport.
"We fought our hearts out, nothing was in our control apart form our own game. Of course, we maybe had one eye on the other games but I see we managed to get a semi-final spot from a centimetre on the draw shot."
Muirhead reached the last four in Pyeongchang four years ago but is aiming for her team, as well as the men, to go further this time out.
"I was in this position in 2018 as well, in the semi-final, and I want to do one better," she added.
"I'm very proud of this team, we have got a great chance out there, as a team we have payed well all week.
"I can't wait to get out there tomorrow night and of course we will be supporting the boys tonight in their semi-final and lets hope we can all do Great Britain proud."
Bruce Mouat's men's team must meet the United States, the reigning champions and the only team to get the better of them so far.
However, Mouat is in no doubt his side have moved on since their 9-7 loss last Friday, and believes the setback in what was only their second game in the competition will not prove a decisive factor.
Mouat said: "We've learnt a lot about the ice in the last four or five days. We know what kind of throws we need to make shots.
"The second game that we had was against the USA, which we did lose, but we've learnt so much from that point that I'm really confident we can come out and play better.
"We will just have to relax into the game and try and not feel the extra pressure that the semi-finals is going to put on and just try and enjoy ourselves which is when we play our best."
Mouat and his team-mates Hammy McMillan, Bobby Lammie and Grant Hardie came into the tournament as the world's number one-ranked team and runners-up in last year's World Championship to Sweden.
The Swedes, skipped by veteran Niklas Edin, whom Mouat's men defeated earlier in the competition, face Canada in the second semi-final.
