No, an "unbroken loop" is not the same as a "closed loop". Although the latter can have two different explanations, an "unbroken loop" does not dictate the start- and endpoint to be the same. In fact, that would be weird in real life (take the Hyperloop for example). With a loop (in travel) you can traverse in both directions, that's all. I regarded that puzzle as a snake game.
So after seeing the correct (accepted) answer, I understood what the intention was. But that was too late for me, obviously. Asking a question was not in my mind, as I hadn't realized that ksolymosi might think of a loop in a different way. Also, I kinda agree that allowing questions clutters and takes away part of the fun (in other words - getting what is meant is part of it).
Having said that. It still can be frustrating when that happens. In any case, I wholeheartedly agree with the notion that ksolymosi decides no matter what.
