Can this really be Sudoku? All of the regular rules apply—with a twist. You’ll start with a blank grid and some simple number clues. With logic as your only weapon, you’ll unlock the puzzle. That’s when the Sudoku rules come into play. It’s two games in one—and twice as addictive as the original.

Classic lines, simple rules, a fascinating challenge—Killer Sudoku isn’t more difficult, it’s just a more satisfying puzzle experience.
