**Edit**
to see specific proof for specific solution, you need to solve the puzzle and count the number of parallel lines (either horizontal or vertical) in the loop then add that number to the end of the solution link in order to get the correct link.

***Edit***
the above rule has been deleted
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

here're some of my puzzles, play if you have time, tell me if you have another better solution.

[jcsl17]                                                           difficulty: very hard

solution

[jcsl27]                                                   difficulty: extreme

my solution for this is extremely ugly, so hope for another better solution.

[jcsl12]                                                                   difficulty: hard

solution

[jcsl15]                                                                   difficulty: hard

solution

[jcsl25]                                                 difficulty: very hard

solution
about my solution, top cross at r1c6, top line at c5r5, top line at c4r5, both of them are explained by the relativity of symmetry.

I couldn't do the extreme one [jcsl27] on paper... just got a few lines and a cross. So I let my puzzle solver have a go at it - it took AGES but got there in the end. So there aren't any other solutions.

I like the solution to this one... That is if it is the only one.

Two solution. This pattern can form extreme puzzles, I've posted  this before,
with size 6x6 is already very difficult, I don't want to creat similar puzzles with bigger size because I don't think that's for human.

This has nine solutions.  Numbers can be added at (1,8 ) (3,1) (8,10) (10,3) (these are row, column coordinates) to make the puzzle unique.  If these new numbers are all 2s, then the symmetric solution is forced, while various asymmetric solutions can be forced by making some of these new numbers 1s or 3s.

Unfortunately, it's not unique.  There are at least several thousand solutions, but I can't say exactly how many, since my solver can't do the count in a reasonable time.  Many numbers have to be added to the puzzle to force a unique solution.

I took a few minutes to write this when I was at school today:

[jsl10+]                                                                  difficulty: easy

solution

If anybody have a difficulty in reading my solution, take a look at these:
(these are basic concepts, if you want more, try jsl10+ or read my solution)
deduce that the little "?" is a line.


If one mouth have two points, and big "?"s in each mouth (excepting r4c3) both have at least one "?" is at least "1", then both mouths must be opened, that means none of two points in both mouths can be blocked to form a corner situation. also deduce that there's one line go to r4c3 from pt.r5c3.

[jcsl36-03]                                                       difficulty: extreme

solution

In my solution, the "2" at r8c5 is partially ignored in the analysis.
Actually you can play directly with the corner 3-n2-3 extreme situation and get a line on the right of the "3" at r6c10, but it's too complicated... I think.

Edit: Kwon-Tom Wrong also: change the "3" at r6c10 into "1".

[jcslli01]                              difficulty: normal

solution

I wrote it in school today,
everything are normal BUT all numbers INSIDE the loop TELL LIES.

so sad,
bad connection lower my result today,
especially the Wrong, it loaded for about 2 minutes to send the result !   T^T

A very nice idea. However, the solution seems not to be unique. You can put the south west cornered 1  inside the loop, and all other squares as in your solution, isn't it?
