I can't seem to get through the Tough ones and I am pretty good at deductive reasoning. I've read the advanced strategies but don't find them applicable to most of the puzzles. Invariable i get stuck in the early running (and don't want to guess). Is there anyway to send someone what I ahve saved so they can point out a next step?
 |  |
15:02 with one guess. Cs, I made it a long way before I had to guess in this puzzle, but still I get to the point where I just don't see any way to eliminate any more. Anyway, don't think I'd be much help. I am getting better about my guesses, though.

Hi Cs from usa!

Eventually, the blog at this site - the link is in the upper right corner - will deal with advanced strategies that do work on most, if not all, of the tough puzzles from this site. Please be patient as it will take a while to get to those types of strategies - but if you More...

A proof for not very tough sudoku of 12 23 06:
1) Start at 23 filled - the given puzzle. Unique Possibilities to 27 filled. (UP 27).
2) Locked 5's t c12 forbids c45=5 UP 30
3) Hidden pair 58 at h12 forbids g12=8, h1=126,h2=26 UP 48
4) Pair 16 at c35 forbids c149=1 and forbids c1249=6 More...

Today's puzzle unravels using some things already covered in the blog, pluz one technique not yet covered. Locked candidates, hidden pair and naked pair have already been covered.

Step 5 in my proof above decoded - with some clumsy notation:
For this decoding,
=> means implies
<> means does not equal.

Note the following:
1's in box e8 are limited to two locations:d8,f9
1's in column g are limited to two locations: g9,g3
1's in box b2 are More...

BTW- When I first starting visiting this site - almost exactly one year ago, I could not understand gb's proofs at all.

I struggled with the puzzles using my own clumsy logic for some time, and just sort of breezed over gb's elegant proofs.

When I finally broke down and tried to More...

This is a different view. Nice picture of a sunny day at the market.
 |  |
23:39 - with a moderate amount of guesses! Merry Christmas to all and to all a good night.
 |  |
21:50 First time I ever finished a tough without guessing. Probably an unusually easy tough? When I get a chance, I will work on understanding the information in the Blog. Thanks Steve.

Mary, Parap Markets are in Darwin - about 3 blocks from where I live. It's a great place to go for breakfast on a Saturday with lots of tropical and Asian food tastes available from laksas to satays to fruit drinks and icecreams, pacific island sweets etc - There used to be a bloke who took the More...

Have a cool yule every one!

Step 3: Is there really a 'Hidden pair 58' at h12? I see 5's other places within the box, rows and column. Thanks.
 |  |
Nevermind. I've got it now--The pair 16 solved everything. Sorry.
