Harry was in his element rushing around the court on Friday, crashing into opponents with glee and scoring tries as he launched the one-year countdown to his Invictus Games in Birmingham during his visit to the UK.
At one point he threw a blind pass over his head straight into the arms of a teammate, who crossed the try line, a move praised by TV presenter Ade Adepitan who won a bronze with the GB basketball team at the 2004 Paralympics.
The broadcaster, a member of Harry's team, who ran out 7-1 winners, said: "He did a no look pass. Did you see it? A no look pass over his head.
"I mean, he said to me at the end 'it was just a throw and hope' but I said 'style it out, style it out,' that was done on purpose."
The event was part of a series of showcase sports highlighting events that will be staged when Birmingham hosts the Invictus Games.
Missing was the Duchess of Sussex, who was scheduled to join him at the event but did not fly to the UK this week because of security concerns.
But Meghan is widely expected to travel with their children Prince Archie and Princess Lilibet in the coming days, prompting rumours of a meeting between the King and his grandchildren.
Adepitan, said about wheelchair rugby, a favourite sport among fans at past Invictus Games: "This is a fantastic exhibition, a fantastic opportunity for people who've never seen the sport and never seen these athletes compete.
"And you know, when you're on there, you've got to do it justice."
