Hello there, I'd be much obliged for some help with this especially fiendish Su Doku. I was able to complete Thursday's but have only been able to discover three numbers -- and have spent hours looking this one over! I've discovered the 6 in the bottom left box of the upper left quadrant, the 4 in the middle box of the middle left quadrant, and the 7 in the middle right box of the bottom middle quadrant.

This is as far as I've gotten (not very far at all, eh?):

*** *** 2**
*58 **6 ***
6** 3** *85

*1* 47* 6**
946 *** 5*7
**7 *** *4*

76* **8 ***
*** 9*7 81*
**9 *** ***

I've mapped out the possibilities in pencil in the other boxes, and see where some numbers can only go in one of two boxes in a quadrant, and two boxes where only 2 or 3 can go. I've also looked at the other posts on this puzzle, but have been unable to figure out how those numbers were discovered.

I'd be very grateful for some hints and suggestions on what to do next, how to go about finding the next numbers, and solving the remainder of this puzzle.

Thank you very much.

To find the number in r4c6:
look at r5c4, c5, c6

You will then be able to find the number in r6c4

You stared with the wrong clues: http://www.timesonline.co.uk/article/0,,18209-1609328,00.html

You are missing some clues on row 6.

Thanks so much! Not sure how that happened, but with those two extra clues, the rest of the numbers came like floodwater.
