Yesterday, I got my pen-pal to teach me the rules of Slitherlink. I had to use a translator to understand what she wrote though, and as a result I suspect I've misunderstood some of her points. I've tried all of the Slitherlink puzzles on this site, but I think none of them have valid solutions!
Oh well. If I can't solve others' puzzles, I'll just have to create my own.
Can you find the unique solution to the following Slitherlink I created, and tell me how I have misunderstood the rules?
