Singles starts with a grid full of numbers. Shade selected squares until every row and column has no repeated numbers. Shaded squares cannot share an edge, and the remaining squares must all stay connected. Circle a number to mark a square you know should stay clear. James Harvey adapted Nikoli’s Hitori for Simon Tatham’s collection.
