Daily Sudoku — Today’s Three Puzzles

Daily Sudoku uses one UTC day

Daily Sudoku changes at 00:00 UTC. Local midnight can be different, and a clock change does not replace an active board. All languages share the same fixed IDs for each difficulty. Choose a dated link when discussing or printing a puzzle.

Continue your daily board thoughtfully

Daily Sudoku progress and completion records belong to this browser. A hint responds to current entries; a walkthrough begins at the original. Viewing answers does not finish a board. For consecutive dates, finish at least one daily board for each relevant UTC puzzle date; older replays keep their original date.

Daily puzzles change at 00:00 UTC. The date shown in the game is the UTC puzzle date. A new day does not replace the puzzle you are currently solving. Completion and consecutive-day records are stored on this device.

Progress is saved locally in this browser. Free and daily puzzles keep separate progress for each difficulty. Pausing or leaving the active page stops the timer. Changing language does not create a different puzzle. Clearing browser data or using another device does not transfer your save.

Sudoku rules: three constraints, one certain move

Fill every row, column and 3×3 box with the digits 1 through 9 once each. Arithmetic is not required. A candidate is a possibility; a full-size entry is a number you have decided. Before placing a digit, check all three constraints.

Sudoku controls leave room for reasoning

Select a cell, then enter 1–9 or use the number pad. Notes keeps small candidates separate from entries. Erase removes an entry or note; Undo restores the previous action and the notes cleaned by that action. Check compares entered digits with the solution. A hint first shows where to look, then why the move works, before you apply it.

Take a Sudoku puzzle to paper

Choose a verified original puzzle and keep its ID with your printout. The original shows only the givens; current progress includes your entered digits. Answers are separate so you can decide when to look.
