Times Superior Soduku 29 - Cant see how to progress

Postby Tumbleweed » Thu Mar 02, 2006 10:00 pm

This is the original

6xx x9x xx4
x91 3x4 28x
xxx xxx xxx

x5x x2x x9x
x2x 8x7 x5x
x8x x1x x4x

xxx xxx xxx
x14 9x2 57x
9xx x4x xx3

Which I can resolve as far as;

6xx 29x xx4
x91 3x4 28x
x4x xxx 9xx

15x 42x x9x
429 8x7 x51
x8x 519 x42

xxx xxx 4x9
x14 9x2 57x
9xx x4x xx3

And then I'm stumped. Now there are a few squares which only have two solutions, for example 1,6 is 3 or 7, by guessing on one of these I can then do the rest, however I cant see a logical way of choosing for that or any other square at this point.

So, I've completed it, but Id welcome something which says how to do it logically without a pure guess. Did I miss something obvious or is it difficult?

TIA

Cheers
Joe

Hi Tumbleweed.

You have a X-Wing on "6" in rows 2 and 8.

Doh!!! talk about obvious. I must have spent 30 minutes staring at the bloody thing on a train yesterday and couldn't see it!

Thanks
