How Bounded, Torus & hints work
Bounded: every pipe end must meet a neighbor and no pipe may point outside the board.
Torus: the left and right edges connect, and the top and bottom edges connect. The finished network is connected and loop-free.
Lock only what you know. Right-click or use Lock selected as a pencil mark. Hints respect those locks and mark the run Assisted.
Hint semantics: when propagation proves one orientation, the hint says it is forced. If a Torus position still has multiple valid completions, the preview is labeled a valid continuation rather than a unique answer.
