How Daily Sudoku works
Choose Classic or Killer, then fill the nine-by-nine grid so each row, column, and three-by-three box contains the digits 1 through 9 exactly once. The given numbers cannot be changed.
Classic Sudoku
Use the given digits and the row, column, and box rules to work out each missing number. Pencil marks, Check, and logic nudges are available when you want them.
Killer Sudoku
Keep the Classic rules and solve the outlined cages. The digits in each cage add to its small printed sum and cannot repeat within that cage. Cages can cross box boundaries.
Today and the archive
New Classic and Killer puzzles appear each day. Use the calendar above to revisit available dates. Today’s two clears count toward daily progress; archive clears do not extend the current daily streak.
