PostForum: General discussion   Posted: Wed Dec 14, 2011 1:01 am   Subject: Interest in Sudoku?
It's been a while - but out of curiosity I revisted this forum and was interested in the comments about declining interest.

For a few years I was an avid participant of the sudoku forums.
I can r ...

I used ERs to remove the 4 and 9 from R1C6 then an xy wing on 147.

OK, give it a name.

My last word- I promise. If it's a Hidden Unique Rectangle call it a HUR
(or BEN).

Marty: Sorry for being pedantic - but if it doesn’t need an xy wing and always works with just strong links – it deserves better than a “Type of Hidden” or an “Almost” Type 6 UR. Evil or Very Mad

Technically that's not a Type 6

Marty: I always thought Type 6 URs had diagonally positioned pairs with only two of the numbers in any row or column. Thus, one can remove that same number from the ...

My very clever solution was a Type 6 UR for 35.

There are only two 3's in C3 so remove the 3 from R4C7. There are only two 5's in R5 so remove the 5 from R4C7 - leaving a single 2.

For a wingless two-step solution, I used a Type 4 UR (89) and an ER on 5.

I used a Type 6 UR (79) and a Type 4 (47) and an ER on 7. Probably more than needed.

Don't know what a sis is short for. I assume it's not a sibling or a girlie guy.

I guess that dampens my clever two-step solution – colouring on 9 and 157 xyz wing. Sometimes the advanced steps are easier to spot than the triples.
Anyway – Happy Victoria Day !

ERs remove the 9 from R7C8 and the 2 from R7C5 - and Bob's your uncle !

R7c1 was a given.
Yes - I wasn't thinking straight. Don't remember seeing many singles in a row.

Marty: The only way I see to get rid of the 8 is a UR on 78. And then I don't see a triple. A quad maybe (though not really needed).

a twostepper: An x-wing on 9 revealed a triplet 124

I also used an ER using the 4s in Box 3 and the two 4s in C3 to eliminate the 4 in R9C9.

cgordon, I agree with you. The Daily VHs really lack variety - and finding a "different" solution often involves "unnatural acts"!

I agree with you too Peter J - though it's bee ...

Thanks Ted and Peterj - I appreciate the detailed responses - but to be honest, for me, these solutions go from fun to painful. In fact after 4 years I’m even wondering whether the Daily Sudukos even ...
