Tthe rule for circled 3s could be a bit ambiguous, at least to non-native English speakers. Those cells must not have 3 walls next to them. Is it
"must (not have 3 walls)"
or
"(must not) have 3 walls"
?

Thanks for the comment Deb. I'll try making a slitherlink only with that rule and not with the corral rules.
Paul, I think a better way for me to state the rule might be that cells uncircled 3s must have 3 walls and all other cells must have less than 3 walls. Does that make sense? I'll see if I can clarify that in the rules on the puzzle sheet.

Yes it does.

These are great puzlles, I really enjoyed them. Thank you David.
I have a problem with the second puzzle (top right), though.
Should not the square (9,7) (reading across and then down, ie the square third from the bottom of the right hand column) not have an uncircled 3 in it? The combination of the two cells below it and the one above seem to force that.
Or have I misunderstood or misreasoned?

Hey there visitor - thanks for reporting that problem. You're exactly right; it looks like after fixing the puzzle once I forgot to add that 3. i will do so immediately and repost.

That would be me. I didn't realise I needed to create an account and log in.
I only just found your site by following a link from Sudoku Extra.
The puzzles are superb!
Thanks David.

That's alright Martin, and you didn't have to make an account, but it's cool that you did.
I found a bug in my comments handling that turned usernames into the name of the puzzle by mistake and have fixed it, so I'm going through the database to fix as many comments as I can now. Sorry about the trouble!

Very nice puzzles David.
I like that fact that "all 3s are marked" more interesting than the "corals"
Thanks for sharing.
