This year, Rugby Seven is back to town and all people are longing for it.  To celebrate, we created a platform "SEFUN's in the AIR" and launched a mobile game for audiences to have fun in the stadium, catch more QR codes as they can to earn prizes through a series of video which showing in the big screen in Hong Kong Stadium, the stickers around the stadium and the QR codes which printed on the tees of a group of rugby squads.
