You expect a WORD Sudoku puzzle from me! But I couldn’t resist this. ABC News posted a story today on the work by Finnish mathematician Arto Inkala, who designed what’s believed to be the world's most difficult Sudoku puzzle (http://news.yahoo.com/solve-hardest-ever-sudoku-133055603--abc-news-topstories.html).
Here’s the puzzle…and the solution. Try to solve it! I agree, it’s the hardest I’ve ever done. Good luck.
