Puzzle Description:

Someone else made a dumbell puzzle but used a background. I wanted to see if it was solvable without it. I can't seem to get it started. Any suggestions?

For me it is not solvable without guessing.

I solved it without guessing. I took the 9 in c5 and used edge logic to eliminate most of the squares in that column. After that, the rest was fairly simple. Thanks.

Found to be solvable with deep lookahead by infrapinklizzard.

Yeah, I had to save and revert, but I can see it as deep lookahead; perhaps *someone* can keep all of those steps in their head.

No, and there may not be one. However, nonexistent proof is not proof of nonexistence. The burden on a logical solver is to prove it, and we don't have proof for that assertion.

I would be very interested in a proof if you have one.

Sheesh, moderate lookahead it is! -- but good luck finding it!

This is one where the moderate lookahead label is a teaser. (Of course, I've been guilty of a few of those, too.)

"Sheesh"?
I wasn't trying to convince you one way or the other Joe ;)
#19: Joe (infrapinklizzard) on Aug 14, 2013
Maybe "Yikes!" is a better phrasing?

This came out so smoothly after a little guess ("9s don't extend to the edge") that I forgot I had guessed at all.

Decided to accept the author's opinion and did not solve.
