DaySudoku

DaySudoku

One Sudoku a Day.

Find the Key9. Place 1–9 before 9 misses.

Today’s Key9 Misses 0/9 00:00

How to Play Key9

  1. Fill the 9 highlighted cells.
  2. Use today’s fixed tiles, 1 through 9.
  3. Unlock today’s Sudoku before 9 misses.
  4. Continue and finish the full board.

Correct tiles lock into the board. Wrong tiles return to the tray and count as misses. Unlock the Key9, then finish today’s Sudoku.

Why DaySudoku is different

DaySudoku is not an unlimited Sudoku portal. It is a short daily Sudoku unlock puzzle designed for a clean, focused break.

Sudoku Tips

Look for rows, columns, and boxes where today’s tiles have fewer possible places. The best Key9 puzzles have one clear starting point and a clean finish.
