A 14-year-old Math wizard fought 150 players in an international sudoku competition in Singapore last week.

Sarah Jane Cua, a sophomore student at the Pangasinan Universal Institute, won first place in Brand’s Asia Pacific Open 2008 held at Singapore’s Vivo City from July 11-13.

Cua told GMA News that she overwhelmed her competitors not only with her mathematical genius but also with her speed.

Sudoku is a logical puzzle played by filling in the game board so that the numbers 1 through 9 occur exactly once in each row, column, and 3×3 box.

The Filipino sudoku champion brought home $10,000 cash prize, in addition to a trophy and certificate.

Cua returned to Singapore yesterday to compete in the International Mathematics competition.
