Daily Sudoku for Sep 13, 2026

The Sep 13, 2026 daily is a stable Easy classic Sudoku with 40 given digits. It is not the same grid as yesterday. Notes and hints stay available while you play.

What is different about this date

40 cells are filled and 41 are open. The puzzle seed is fixed, so Sep 13, 2026 always rebuilds this grid.

Row 5 already contains 6 digits, more than any other row. Close that row before you jump around the board.

Technique to try first

Look for a hidden single: a digit that can live in only one cell of a unit, even when that cell could hold other digits on paper.

Hint for this date

A hidden single lives where a digit can only sit in one cell within a row, column, or box—even if that cell has other candidates.
