Bandy, played mainly in the Nordic region and Russian Federation, is similar to ice hockey but played with a small ball instead of a puck and with larger pitches and goals.
William and Kate watched the popular activity in a snow-covered park in the Swedish capital, Stockholm. "As the Duchess of Cambridge is so much in the public eye, we hope the message that the charity can help children and young people with hair loss will reach everyone who might need our assistance", said charity manager Monica Glass.
Proving she's no snob when it comes to hairspray, Kate opts for the all-time favourite, Elnett Supreme Hold Hairspray which is known for its superior holding quality, which costs just £5. William and Kate did not lace-up any skates but did take part in a shootout which the Duchess lost.
The Duchess takes a swing.
When the duke scored, the duchess matched him and raised her first in triumph - but after her husband whacked his second goal into the net, she fired wide with her final shot.
"I could see that maybe they like to beat each other", she said. "But lots of people don't fill in the paperwork and they don't feel the need to be acknowledged in that way, but we are always very grateful".
But seriously, who looks this cute while playing hockey?
Tucker snapped a private Instagram photo of all the loot she's taking to keep Middleton's hair looking picture-perfect on the upcoming royal visit to Norway and Sweden, and that post has obviously since gone viral after one eagle-eyed follower shared it for the larger masses.
Later, the British royals had lunch at the Swedish Royal Palace, hosted by King Carl XVI Gustaf and Queen Silvia and with a dozen other members of the Swedish royal family attending. "You get a lot for your money there". All the really interesting discoveries were made by accident.
