Puzzle #462: Think Three Slitherlink

In this special shotgun slitherlink, all of the clues use the number 3! It's inspired by a puzzle by the ever-talented MellowMelon.

While we're at it, I think that the first puzzle is unsolvable; you might have left out a 3.

Thanks for the message Grant. The unboxed 3's are what need 3 walls, not boxed 3's. I'll see if I can clarify the rules and repost it later today.
As for the puzzle being unsolvable, I test solved both of the two puzzles twice, but I'll check again just to be certain. If you could e-mail me what you have for the top puzzle though and point out a trouble spot, I would appreciate it.

Found the culprit Grant - a 3 I missed. Fixed the PDF now and it has better instructions. (Hopefully better anyway.)

The PDF seems to be unchanged. The "tur.n" typo is still there.

I think its still the old version of the puzzle

Sorry. I don't know what happened. Even after uploading it TWICE it still showed the old PDF. I refreshed a few times and now it should be the right one. The new version has a small sample grid in the lower left corner to distinguish it from the original.

Typo: "but tur.n before and after" has an unnecessary period in "turn".
Clarification: "Each cell with a 3 must have 3 walls around it as part of the loop." How does this rule apply to the boxed 3's, 3+3's, and 3x3's? As written, the rule says that these cells must also have 3 walls next to them, and not just the cells with non-boxed 3's. However, I don't think the puzzles are solvable that way. :)
