Kate, who is pregnant with her third child, was beaten in a penalty shootout by her husband when they joined a group of young Swedes playing the game on an outdoor ice rink in downtown Stockholm.
Decked out head-to-toe in warm winter gear, Kate opted for a warm, double-breasted, 100% lambskin Burberry black coat.
Fifteen-year-old Lucas Tinseau was on hand with questions for Kate; he quizzed her on her knowledge of rap music: "I asked her if she knew J Hus", Tinseau told the Daily Mail. They cost between £84 and £120 and are still available now. The dress doesn't appear to be on the website, which suggests it is a previous design or it has not yet come been released on sale.
What Kate wore: Choosing green again, Kate cosied up in a green Catherine Walker fur trimmed coat and alpaca hat, which she wore on Christmas Day too.

Kate has also given a nod to her household furnishings in a turquoise and orange floral midi dress, which she wore to visit the Princess Diana Memorial garden in August. Middleton kept her accessories the same, simply adding a pair of gloves to combat the chilly weather.
The Duchess turned to Erdem when she needed an ensemble fit for the grand Trooping of Colour parade in 2012 and the designer didn't disappoint, creating a bespoke powder blue dress with a rolled scoop neckline and attractive embroidery. Kate's a long-time fan of the London-based designer. Prince William and Catherine, the Duchess of Cambridge might be British royalty, but clearly, they aren't immune to a good bargain like the rest of us.
Hiding her baby bump with the bold print, the duchess matched a burgundy quilted Chanel handbag to her favorite Tod's fringed leather loafer pumps. Further accessorizing, she completed her look with earrings by Swedish designer In2Design.
