Slitherlink Puzzle Challenge

I recently discovered a really excellent puzzle in the newspaper - it's called Slitherlink or Loop the Loop.
Here's a challenging puzzle. It's only a 6x6, but it'll take a while
https://ibb.co/RSkfcr2

Rules of Slitherlink:
1. You have to make a full closed figure, where the numbers signify the number of lines around it.
2. Empty squares can have any number of lines (or links) around them.
3. There should be no overlappings or branchings of the lines.

I recommend

Re: Slitherlink Puzzle Challenge

hi CurlyBracket

I've seen these in newspapers too, and I agree, great puzzle. I'm working on it.

I'm only seeing the picture; not the rules; so for anyone who hasn't seen these before this is what I think is the correct rule:

Join the dots with one continuous line, back to where you started.  The numbers indicate how many line segments surround that number.

Re: Slitherlink Puzzle Challenge

Hi Bob,

Yes, I've added a slightly detailed rule list (only three rules, there aren't many) to the main post.

P.S: I've changed the signature. How is it now?
