Used orphans

Orphans not needed, unique rule solves it again

One small chain

Chris +1

no orphans necessary
chris, please explain the unique rule

no orphans but a chain.
Same question as Joe for Chris.

also waiting for rule. Took a guess where the 4 where the 4 went on top then it filled in

6:16 with orphans and a chain

4:48 My understanding of the unique rule is that there can only be one solution which eliminates some possibilities where more than one solution could be possible. In this puzzle the 17 down has to be an 8 and 9 and to have a unique solution the 19 down must be 3 with a 7 and 9 as 2 with 8 and 9 would provide 2 possible solutions for 35 and 26 across. Hope this helps!

No orphans. I think the unique solution rule puts a 6 in the bottom row, otherwise you have more than one solution with the 789 combos. Having said that, it didn't fall into place for me. Had to try chains.

Used orphans. Thanks for the explanation of the unique solution rule. Not sure I understand it, but I will work with it.

Christ + 2

Chris even!

8:05 with orphans (but didn't calc them)

small mental chain to resolve 10A.

11:57

7:22 without orphans but with a chain

It took me 3:25 from the saved point to do the 4 elimination in 10A & and 3:44 to finish using the right cell for the 4 (right after the previous)
