Today we attended The Times UK National Sudoku Championship finals in London where 163 people battled to complete their puzzles as quickly as possible. The first hour long rounds saw many people fail to complete the three puzzles, with the fastest eight going through to the quarter finals.

This championship was challenging to all who attended, the super fiendish Sudoku puzzles made it a formidable contest to all who travelled to London to partake. Friday, 16th March 2007
