I was wondering whether any “World Sudoku Championship” exists. After googling, realized that the first world championship in sudoku was organized at Lucca, Italy on March 10-11 2006. The winner was a 31 year old Czech Economist, a lady called Jana Tylova.

I explored the WSC website and downloaded the Official instruction booklet. The number of Sudoku variations in the tournament is quite amazing! In total they have 27 variations…Pips, 0-9, Classic, <>, Diagonal, Sum, Odd/Even, 147, Irregular, Toroidal, Multi, Extra-Regions, Outside, Consecutive, Frame, Star, Pandigital, Mini, Product, Digital, Irregular 6x6, Multi-mixed, Irregular 12x12, Mechanical, Combined, Cubic and Word Sudoku! Huh…understanding the rules itself will take time

BTW, The World Puzzle Championship will be held at Bulgaria this year from October 7-12. If you are interested, explore the website to know the details. I am going to try out the sample puzzles given at the website during the weekend for my own pleasure!

BTW, the title is Japanese version of the word “SUDOKU” (Suuji wa dokushin ni kagiru) Source: Wikipedia
