I can't solve it with logic either - are you confident it doesn't require a little T&E?

Where did it come from?

This puzzle definitely does require trial and error, however it has a unique solution.

Code: Select all
`8.3|.29|716..6|.18|5.4...|.6.|..8-----------..5|.46|.8.7.9|.35|642.6.|.9.|1.5-----------6..|.7.|.51..1|65.|8..5..|981|463`

See where 7 can be in row 4. See what happens to (2,4) when you put 7 in either place in row 4.

I got it from the site www.sudoku.org.uk - no guarantee that it doesn't require trial and error but I assumed (probably a bad idea) that a site dedicated to sudoku and full of regular players and the like wouldn't publish puzzles that required T&E...

Anyway, thanks for the help
