Hi Knotwilg,welcome to this site.Please check your step 2. I aggree when a4=9,a6=4, but when a4=3,i4=8,i6=4, and a6 becomes 9. What do you think? Regards, Alfred.

Hi Alfred

We agree a4=39 and a6=49

In the ghi-456 box, the following hold
- 3 is at h5 or i4
- 9 is at h5 or h6

So, if a4=3 then i4 is not 3 then h5=3 then h6=9 then a6=4

And if a4=9, then a6=4.
So a6=4 either way.

then follows i6=8, i4=3, a4=3, a1=9 ... and UP 44.

Cheers

Knotwilg! I see you are able to work the proofs...which I am sadly not.
Hope you enjoy your time on the site.
Welcome aboard!

Thanks for stopping by, Knotwilg! I couldn't begin to do the proofs. I just look for patterns and use elimination...sometimes I'm left with guessing. I, too, have long times on the tough - don't know how some people get those fast times. Just filling in all the possibilities takes me the same time that some of those foks use to get it solved! Catch you on the pages...and welcome, again!

Hi again Knotwilg,thanks for the response.Your logic is sound as far as 3s and 9s are concerned, but there is nevertheless a contradiction with 4s.Because i4=3/8 and i6=4/8,when a4=3,i4=8 and i6=4, contradicting a6=4.What this proves is that a4 must be 9 and therefore a6=4.This is a shorter proof than mine.Maybe I misunderstood how you meant it.After a6=4,I found the rest to be UPs.Remember that f5 can,t =6 and therefore =9 and I found the triple 246 at g358 helped with the solution.Regards,Alfred.
