I tried to use the hint for the following code
| Code: | . 6 1|7 . .|. . 2
. 7 .|. . .|6 . 1
4 . 2|. . 1|. 7 .
-----+-----+-----
. . 5|8 . .|. 1 .
. 1 4|. . .|2 . 8
. 2 .|1 9 4|7 . 5
-----+-----+-----
. . 7|4 1 .|9 2 .
2 4 3|. . .|1 8 7
1 . .|. . 7|. 5 . |

I will try to update the documentation a.s.a.p.
This is how the hints work:
when solving the puzzle, the solver writes entries into the log. Only those entries that bind a digit to a cell are used as hints. The log entry contains a reference to that cell.
When you ask for a hint, the program scans the log for hints, and shows you the first one that references an empty cell.
When you remove a candidate, you still haven't placed a value into that cell, so it will persist in giving you the same hint, until that cell is filled.
To move on to the next hint, just do as the hint says. |

This log entry was incorrectly flagged as a hint. I have fixed the problem.
The fixed version can now be downloaded from my homepage. |

 release 1.1.0
The new update is now available and can be downloaded here.
No charge, no ads, no nonsense, just fun.
This version now supports tabling, 3 ways to copy a grid to the clipboard, does all 4 uniqueness tests.
A very useful feature is control-click a candidate in Ultracolor mode. It does a little tabling and applies green/red colors to all the true/false states of each candidate found in the implication chain. The tabling function only takes the candidates into account that you have enabled/disabled in the user interface. Now you can solve these fiendish puzzles without writing your own tables.
I have replaced the off-worldly bar/stack implementation with common Line-Box interactions, making the interactive log a little more readable.
If you encounter any problems, please notify me here or by the e-mail address on the site. Other comments are also welcome. No more request for source code please...
Enjoy.
Ruud.

I had some time to spend, so I made a few more improvements.
The log does now speak the same language as the people here on this forum. It can also be copied to the clipboard.
The analyzer dialog shows a count of all solving techniques it has used to solve a puzzle, including the number of placements for which it needed the backtracking solver.
However, the best improvement is the one you don't see. The entire maintenance of candidates takes place with the data structures (nodes) that are also used by the DLX routine. This gives the DLX solver a head start because it does not require separate initialization. It allows me to merge logical solving techniques into the DLX process at any point, finding shortcuts that may cut out complete branches in the solver. This looks very promising.
I've put a few links on my site. If you want to exchange links, I'm happy to do so. Just send me a PM or e-mail.

Had a lot of building this one:
The Dancing Links Visualizer.
This is how you do it:
-. Get the latest verion 1.1.2
1. Menu/Tools/Options tab Solver, disable all solver options except dancing links
2. Menu/View/DLX
3. Put up some music
4. Open one of the top870 sudokus
Don't forget to reenable the solver options.
Have fun,
Ruud. |

Rudd,
The explanation of DLX is super.  Even I may be able to implement it 
I believe the program does not update the other candidates when it automatically updates singles (only candidate).
Is it necessary when Marking candidates is on to refresh them manually?

This is an optional setting in the options dialog: "Automatically update for direct blocks".
| Quote: | | Is it necessary when Marking candidates is on to refresh them manually? |
That is the default setting. There are 2 alternatives:
All solver results (disable the most advanced solver techniques, otherwise you will only see the solution)
Singles only. ("direct blocks" setting).
Personally, I like the "manual + auto update direct" combination best.
