Chinese elements add interest to Sudoku competition
This year's Beijing International Sudoku Tournament had an exciting factor - Chinese elements.
"This is the first time that the binary system and mosaic, which are some of the concepts used in Chinese puzzles, have been used in an international Sudoku competition," says Chen Cen, the 27-year-old designer of both this year's and 2011's puzzles. The three-day annual competition ended on May 20.
Citing an example, Chen says in one of the rounds, instead of putting correct digits into the regular 9x9 grid, participants were given the Eight Diagram, a Chinese philosophical concept from Taoism. The Chinese-concept Sudoku puzzles were designed based on the creativity of the designer and not computer-generated.
