Hosts and Olympic bronze medallists Norway got their campaign off to the perfect start with a six-end victory against Slovakia.
Kristin Skaslien and Magnus Nedregotten proved too strong for Silvia Sykorova and Marek Sykora as they earned a 10-0 win in Group D.
England, represented by Anna and Ben Fowler, swept aside Qatar 12-5 in the same group.
"We were just taking the game to figure out the ice conditions, so that was a really good game to settle us into the conditions," Anna Fowler said.
In Group E, there was no fairytale start for Saudi Arabia – one of five nations making its first appearance at the Championship – as they were hammered 12-1 by South Korea.
The tournament continues tomorrow.
