Interesting way of tackling it, may try that next time I take a stab at another Sudoku on my DS.
(too bad you cant "paint" on finished answers for annotation in the Brain Age Sudoku's though)
What I normally do is put possible candidates for each square in when I'm looking for a specific number, then work my way from there, problem as, as noted in the article, if I get distracted, I usually lose track of all the logic I had stored in my head. ;/
