A 16-year-old middle school student grabbed the championship title for Team China at the eighth World Sudoku Championship on Tuesday in Beijing.
It is a breakthrough for the Chinese team, and China is expected to one day become a major force in sudoku competition, said Chen Cen, chief organizer and referee of the championship.
"The Chinese national sudoku team started competing in the championship in 2007 and has made impressive progress," she said. "The young players are especially promising and we are very confident about the future of sudoku in China."
The event attracted about 300 players from 35 countries and regions.
Sudoku is a game that requires each horizontal and vertical line in a square grid to contain every number from one to nine, with no duplicates.
The winner, Jin Ce, said taking the title is something he had never anticipated.
"This was the second time I had competed in a world-class sudoku game, after last year in Croatia, where I ranked 10th," he said.
"I thought I would rank the same and make it to the top ten. I never expected to win the world champion title - sudoku is just a hobby to me."
