SUDOKU CHALLENGE 2007 @ Swiss Embassy

The tercentenary of the birth of the famous Swiss mathematician Leonhard Euler

To celebrate the 300th anniversary of Leonhard Euler, the famous Swiss mathematician who is also considered the grandfather of the SUDOKU puzzle, the Embassy of Switzerland in Tokyo will hold a SUDOKU competition SUDOKU CHALLENGE 2007@SWISS EMBASSY on Saturday, July 21, 2007 at the Residence of the Swiss Ambassador in Tokyo.

Born in Basel, Switzerland, Leonhard Euler spent his very productive life in St. Petersburg/Russia and in Berlin/Germany. He is considered to be the most prominent mathematician of the 18th century and may well be compared with Galileo Galilei, Isaac Newton or Albert Einstein.

SUDOKU first became popular in Japan and gradually reached worldwide fame. Euler’s work on Latin Squares laid the groundwork for today’s SUDOKU puzzles and is such creating a unique link between Switzerland and Japan. The Embassy of Switzerland celebrates the year 2007 as "Year of Leonhard Euler" and will hold a SUDOKU competition with the cooperation of NIKOLI Co.,Ltd., Tokyo.
