harvdog You could make some progress but as this puzzle has no solutions as posted it would not be worthwhile. Is there a typo in the grid?

This puzzle came from last Saturday's Boston Globe (7/12/08). I see now that it was my mistake. I will correct it and try to finish it. Thank You for your time.

Having no idea what the original Boston Globe puzzle is, from your state I removed all unsymmetrical clues, and then removed the 9s from r1c4 & r9c6:

Code: Select all

....5.4..
4..31.67.
.6.2.....
..3..1.67
..5.8.1..
91.4..5..
.....4.5.
.34.25..1
..2.3....

This puzzle has a unique solution and is solvable by singles/pairs.

In the future please post the original puzzle as well if you don't want to waste the time of other people.

You are spot on udosuk it matches the grid on the Boston Globe site perfectly. Ranked as 5* so reasonable for a newspaper offering.

If you care ...

Boston Globe, USA Today, Seattle Times, LA Times, MSNBC, Newsweek and many others all use UClick as their puzzle source. For the lower-budget papers (Seattle Times, Sacremento Bee, Boston Globe...) they all get the same puzzles. Others get better/harder puzzles (LA Times has the best set I've found out of UClick so far).

Cheers...
