Sudoku championship
The Independent has this week begun its second UK sudoku championship. To enter you need to send in nine completed championship sudokus grids. These are being printed daily and yesterday’s was the first of fourteen. As last year, everyone who submits nine correct puzzles will be invited to a regional heat where they will compete against the clock. The top 100 will then go through to the final and the chance to succeed Ed Billig as the champion.
