World Sudoku Championship
The World Sudoku Championship is an annual international puzzle competition organised by a member of the World Puzzle Federation. The first one was held in Lucca in 2006. National teams are determined by local affiliates of the World Puzzle Federation. The competition typically consists of 100 or more puzzles solved by all competitors over multiple timed rounds, including classic sudoku, variations and other puzzle types, followed by a playoff for the top qualifiers to determine a champion. Examples of rounds include the Relay round, where an answer from one puzzle contributes digits to the start of the next sudoku, and the "World Record" round, in which solvers competed to set a Guinness World Record for fastest sudoku solution.
Of the 12 championships held so far, Thomas Snyder of United States (2007, 2008 and 2011), Jan Mrozowski of Poland (2009, 2010 and 2012) and Kota Morinishi of Japan (2014, 2015, 2017) have been the most successful winners with three individual titles each, they succeeded to Jana Tylova of Czech Republic (2006) who won the first individual championship.
From 2007 there has also been a team competition. Japan is the most successful team, having added the title won this year (2015) to those won in 2007,2012 and 2014; Germany (2010 and 2011) have won this title twice; Czech Republic (2008), Slovakia (2009) and China (2013) also won a title each.
Currently, 34 countries are official members of the World Puzzle Federation. Individuals may also take part if their country is not already represented by a national team. In the latest WPC in 2016 Senec Slovak Republic the number of participants exceeded the magic limit (213 contestants from 33 countries).
