Masyu by Thomas Snyder

[This is a repost from our archives with new notes at the top (original post here): The first set of Masyu puzzles ends with a grid that almost has “twisted” symmetry meaning antisymmetry of white and black circles. Several less conventional steps are required to find the one true loop in this challenging Masyu.]
