A familiar puzzle, with a hidden word.

Every row, column and 3×3 box uses each of the nine target letters once. Exactly one complete row or column spells the target in order. Easy reveals that line; Medium fills it after you identify it. In Hard, confirm the line and fill it yourself. Pro removes revealing hints.
