Sudoku archive9 games, one day at a time. Only published puzzles appear here.
One day for a deliberate puzzle completion, Monday–Sunday in UTC. Opening or restoring a solved board and Undo/Redo do not earn days. Missed days never reset milestones.
Optional, device/browser-local only. Only future completions while enabled are remembered. No account or cloud sync. Clearing browser data removes this record. Turning it off keeps earned days but stops new credit.
One of each number in every row, column and box.
