Talk:Slitherlink

message: It would be cool to have a section on generating the puzzles; what makes them harder? I have thought about the algorithm but don't quite have it all yet.
I have another rule not listed, but no figure for it - perhaps someone could generate a figure? It's that a 2 adjacent to two or more linear 3s has a bar thus:
  _
  2   
 |3|3|
    2
    _

Where a Zero sits on an edge next to a 2, the area surrounding the zero are invalid, leading to known lines being shown.

Where two ones are next to each other on an edge, the line between them is invalid.  —Preceding unsigned comment added by 80.193.71.144 (talk) 15:30, 28 March 2011 (UTC)

message: I've had a go at tidying up some of the text, adding text where it was missing for some of the examples and adding a few images. However, I feel that some clarity and consistency is needed in the descriptions of the examples. Different people have used different terms to describe the presence or absence of lines. E.g. Line = closed = filled and Blank = open = X'd out. I found this very confusing when I first read the page. Even more confusingly, 'line' sometimes means the side of a square (whether open or closed) and 'corner' sometimes means the corner of a a square and sometimes the corner of the grid. I'm willing to edit the page so that the terminology is consistent. May I therefore make the following proposal for terminology with which to describe rules and hints:
* Corner = corner of the grid The context ought to make it clear whether it's the corner of the grid or a square.
* Edge = edge of the grid
* Point = any point, whether at the corner, edge or centre of the grid
* Segment = the interval between any two points
* Side = the side of a particular square (i.e. a sub-set of Segment)
* Closed Filled = a segment/side which has a line
* Open Empty = a segment/side which doesn't have a line
* Line = the line itself

thread_title:  Terminology 

message: I moved the pictures into the center of the wiki beneath their respective sentences, as it was horribly hard to figure out what picture went where when they were all stacked on the right side.  The only thing better than this solution would be for somebody to go to the time of putting them on the right again, and then introducing lots of blank lines so that they still are to the direct right of the sentence referring to them.

replies: text: Also, I noticed that some examples are missing pictures, but I don't have the means to add them. Sudoku424 (talk) 00:47, 9 November 2008 (UTC)
replies: text: The pics were all in the right place when I edited the page on my wife's computer at home (running IE7) but then I saw they were out of place on my computer at work (Firefox 3, in case that makes any difference). I think the answer is to turn the bulk of the page into a two-column table with the pics in the right-hand column but I haven't had time to do that. But thanks to Sudoku 424 for trying!

message: I am the author of Android Slitherlink implementation. I don't feel that I should be modifying the article myself. At the same time I think it's worth including in the video games section. Up for discussion. Thanks.

thread_title:  Android Slitherlink 

message: The image at the top of the page is currently a "Moderately difficult Slitherlink puzzle" with a link to the solution. I think it would be better to show the solved puzzle in that spot. A solved puzzle illustrates the rules ("a simple loop with no loose ends. In addition, the number inside a square represents how many of its four sides are segments in the loop"), so it makes sense to have a solved puzzle at the top of the page where the rules are. I'll probably make the change in a couple of days if there are no objections. Also, I don't think it's useful to rate the difficulty of the puzzle, since it depends on the solver, and won't mean anything to someone learning about Slitherlink for the first time. I think the caption could simply be "A solved Slitherlink puzzle." Axenicely (talk) 18:19, 18 September 2016 (UTC)

message: The rule was initially: "In a closed-off region of the lattice (from which there is no path for any lines to "escape") there cannot exist an odd number of unconnected segment-ends (since all of the segment-ends must connect to something)." 
To which this was added: "and 2) if the first condition is met, and the region contains lines, there must be at least two lines exiting the region (otherwise the segment-ends inside the region could not connect without forming a loop)."
The same rule can be expressed more concisely: "If a closed region is not empty, there must be a non-zero, even number of lines entering the region that begin outside the region." When solving a puzzle, it is only necessary to inspect the boundary of a closed region and count those lines, because the lines that begin and end inside the region will necessarily have a combined even number of segment ends. So, expressing the rule more simply also makes it easier to apply.  — Preceding unsigned comment added by Axenicely (talk • contribs) 14:12, 3 October 2016 (UTC)

message: I've just reinstated a change that removes the list of solving strategies. These seem to be out of place here -- as suggested above starting a Wiki book would be more appropriate if you'd like to keep them around. Or refer to something like Bram de Laat's Slitherlink pattern guide: https://puzzleparasite.blogspot.com/2011/11/slitherlink-pattern-guide_23.html
