I looked at other people's answers for the first four grids, and got the solutions from those. However, here's what I think the fifth grid is (minor spoilers for the other four grids): It has a unique solution:

I've found four slitherlink solutions, but I'm not certain how to construct the fifth...

As in many grid-deduction puzzles (and for that matter well-posed logical deduction puzzles of all kinds), you can usually deduce the solution by pure logic from the given initial conditions. The fact that you can deduce it shows that it's unique, otherwise you'd find more than one possibility. If such a puzzle doesn't have a unique solution, then it's ...

I believe this is the intended solution. (Black lines are part of the loop, while red lines were deduced not to be.) Here's how I did it (I got lucky because of the assumptions I did):

I think I have got the Answer to all 5:-

The solution: Not sure if it's supposed to be something... Anyway, really fun puzzle!

The solved grid looks like this: Path to solution Bonus question:

I think I got the crossword part: But I'm puzzled as for what to do next...

Solved it! It was a lot of fun!

In the picture below, the green line is the unique solution. When the puzzle was first posed, one clue was missing, which allowed a second solution shown in blue.

Nice Puzzle... solved both (edit to merge solutions to clear clutter)

I'd like to point out that there are actually two answers, so this Slitherlink is not solvable through pure logic: and: differing in this little region: To fix the problem, I think it is possible to:

Multiple solutions to the larger puzzle.

The answer is Proof: (This was very well done, although it's a shame that the methods I used were taught to me by my Slitherlink Master - i.e, they were not new to me) Method of solution: Firstly, Next, Now, fill in some obvious stuff and do another chain, one below this one (a blend of twos chained diagonally, with 0 entrances on one end - if we have ...

My solution is: First step: start from mid of top row Second step: Third step: Last step: Combine the ends. One of the solution on my page: that explains possibilities for top 2 and bottom 3's, when i was stuck on second 2:

http://www.janko.at/Raetsel/Slitherlink/index.htm got some puzzles up to 45x31. You can sort them by size (Größe) or difficulty (Schwierigkeitsgrad). http://www.nikoli.com/en/puzzles/slitherlink/ got some hard ones, but only a few free samples. https://www.chiark.greenend.org.uk/~sgtatham/puzzles/js/loopy.html can generate puzzles of any size, limited only ...

Well, look what I found. Another shot at a Slitherlink! Answer: Explanation:

I didn't get any contradictions, but up to here was uniquely solvable (at least by my reasoning, if I didn't make a mistake) using the clues in the demarcated region. Hope this helps!

Meerkat gave the answer but I just had some additional observations: The removed twos follow some oddly specific rules. The first one, I think, is fairly obvious to anyone who solved the question. The second rule is stranger and I can't really claim to understand it. Using those two rules it doesn't always get you a solution, but all solutions follow ...
