Classic Hitori

Each puzzle consists of a square grid with numbers appearing in all squares. The object is to shade squares so:

• No number appears in a row or column more than once.
• Shaded (black) squares do not touch each other vertically or horizontally.
• When completed, all un-shaded (white) squares create a single continuous area.
