This is supposed to be just a hard!

Postby White Knight » Tue Jun 07, 2005 11:35 am

This is a simple "Hard" from the program, started to fill in an odd 15 mins,
but it has me stumped. I have managed to get this far

*1* 9** ***
*63 *** *97
*** *6* 8*4

3** 586 9**
*** *** **8
**6 491 **5

2*5 *39 ***
69* *** 5**
*3* *57 *89

and have picked up all the obvious pairs, triplets and an X-wing or two, but can't see a way forward. I would very much appreciate a tip.

Look for where a 1 can go in row 3.

Take a look at column 4... pay real good attention to the numbers 3 and 7... after that, look at row 3.

Ahhh, the dreaded hidden pair!! It just drops out from there. Why didn't I spot that. It must be senility creeping up on me:D
Thanks for the tip
