Killer Sudoku Productivity + Interactive
Killer sudoku keeps the familiar 9×9 and replaces the given digits with dashed cages and printed sums, with one verified solution and a matching answer key on every board. Productivity + Interactive adds Time Saver batch runs, Puzzle Book Studio Productivity, and the web play and Puzzle Slides lanes, so the same catalog prints, plays online and presents live. Free demo available.
