I agree with you that the rules aren't always clear until you see the correct answer. Like # 56. I entered a correct unbroken loop, but upon seeing the answer I realised a closed loop was the object. Probably due to English not being ksolymosi's first language. Same here, where I assumed/guessed that each region was to be connected with itself (a nonomino so). But it is not to be found in the text at all. This can be frustrating if you miss ksolymosi's intention. P.S. I like your answer; creative!
