Finish a daily puzzle to add your first record. Returning to a finished puzzle does not add another completion.
How the daily puzzle works
The puzzle ID includes its UTC date. Sharing it opens the same starting grid, without your answers. The timer starts when you place your first number and stops while the page is hidden or you pause the game.
Switching to today’s puzzle keeps your unfinished daily puzzles in this browser. Use the “Continue an unfinished daily” menu above the board to come back to them.
A useful daily practice
Start with rows, columns, or boxes that have several given digits. Add pencil marks when a square has more than one candidate. If you get stuck, request a hint and read its explanation before applying it.
