Daily Sudoku challenges

Use the Daily Sudoku calendar to open today’s puzzle or browse past daily Sudoku puzzles by date. Switch between available months, select any published date from January 2025 onward, and start that puzzle from the Play button. Today, playable dates, future dates, puzzles in progress, and completed puzzles have distinct calendar states. Completion and progress are stored locally on the device you are using.

Future dates are unavailable. To return from a historical puzzle, use its calendar link, or go directly to today’s Daily Sudoku. You can also practise at a steady level with Medium Sudoku or review solving concepts in the Sudoku strategy library.
