Polish Man Wins World Sudoku Championship

A Polish puzzle solver named Jan Mrozowski became the world Sudoku champion Saturday evening for the second time, and a team from Germany took home the national trophy after two days of tense play in Center City among about 120 of the world's best Sudoku solvers from 32 countries.

Mrozowski threw his head back in victory after finishing the last puzzle in the final play of the World Sudoku Championship – a round of 10 puzzles that took him 54 minutes and four seconds to complete.

Shortly after that, the civil engineering student from Krakow, who also won the world championship last year when it was held in Slovakia, was hoisting a silver bowl over his head and being hoisted into the air three times by the other six members of his team. The Inquirer, which sponsors the national Sudoku championships, won the bid to sponsor this world championship, which was at the Courtyard Marriott, across from City Hall.
