I've been working on solving puzzles in my Soduku puzzle book for about a year now. I got through the Novice section, no problem. Then got through the Master section with challenge, but not too much. Now, I'm in the Guru section and can't solve them on my own for anything! Urgg. Are any of you Suduku masters?
And, just by the way, how DO you spell Soduku? I find it spelled differently all over. My book shows it as "Sudoku". The internet shows it as "Soduku". I've seen it with varying o's and u's. Hmm.
