I would like to say sorry to all the players who started to play sudoku variants between 00:00 27th September 2010 and 12:45 27th September 2010.

• Assignments are available to download (protected by passwords). The system of solving puzzles is the same as in Sudokucup tournaments.
• Results are available after solving.

It seemed that there is no strength, but finally you broke through the puzzles, finished them and fought with honor.
