Objective: Draw a single loop along grid lines so each numbered cell has exactly that many edges used.

Controls: Click edges to toggle. Use mark mode (✏️) for pencil marks (X). Press Check to validate.

Rules: Each number indicates how many of its four sides are part of the loop. The loop is single, closed, non-branching.
