Stuck on my first hard puzzle

Postby carpenter » Sun Jun 19, 2005 1:25 pm

Guess I'm not as smart as I was hoping I might be.....

this is the start

Code: Select all
*** *3* *5*
3** *** 7*6
*87 *21 4**

*** **6 *29
*** *** ***
24* 9** ***

**8 76* 13*
1*3 *** **4
*5* *8* ***


and where I am at:

Code: Select all
*** *37 25*
3** *** 7*6
*87 *21 493

*** **6 *29
*** *** *4*
24* 9** ***

**8 76* 13*
1*3 *** **4
*5* 183 ***


I have a pair (18) in block 3 cols 8 and 9 but without guessing cannot work out which goes where.

Where should I be looking?

thanks

Take a really good look at box 4.

Thanks, but I still don't 'see' it.

Is this to do with pairs or triples as there are multiple candidates for each cell, or am I missing something much more basic?


cheers

My mistake... I seem to have left some words out of my post...

You have two options:
a) take a good look at box 8
b) take a good look at number 4
