About two weeks ago, I first noticed sudoku in the Washinton Post, and have been hooked ever since! Since I've started, I've been able to beat Monday-Thursday puzzles in about 4-15 minutes, depending on the difficulty; however, I've never been able to beat Friday's puzzle !
I've read some of the pointers on the great sites some of you have published, but I guess I really don't understand some of the proprietary terminology that has sprung up in entheusiast groups like this, and was wondering if someone could give me some "plain English" pointers on this dastardly Friday puzzle!
Here's the original:
|**1|*5*|7**|
|25*|***|*86|
|***|3*6|***|
-----------------
|*7*|*3*|*4*|
|1**|8*4|**5|
|*4*|*7*|*1*|
-----------------
|***|4*5|***|
|49*|***|*67|
|**6|*1*|4**|
Here's with what little progress I've made so far
|**1|*58|7*4|
|25*|***|*86|
|***|3*6|5*1|
-----------------
|*7*|*3*|*4*|
|1**|8*4|*75|
|*4*|*7*|*1*|
-----------------
|*1*|465|***|
|495|283|167|
|**6|*1*|45*|
Thanks in advance for any pointers rendered!
