How To Play

Shade cells so that no number appears more than once, unshaded, in any row or column. Shaded cells can never touch each other horizontally or vertically (diagonal is fine). Every unshaded cell must stay connected to every other unshaded cell in one single group. Every puzzle here has exactly one valid solution.
