I know that I'm more than a year behind schedule, but I wanted to practice my Area 51 a bite more :-) Is it possible that the last puzzle (bottom right) doesn't have a unique solution? According to my solution two fields could be either inside or outside the loop and still give a correct solution : (2nd row, last column) and (last row, last column). Am I missing something ... ?

Hey Tanfasie. That page has an extra rule that every possible 3 clue is given. If you apply that added constraint, the puzzle solves uniquely.
