Daily Sudoku

How to Play

Every day, a new Medium-difficulty puzzle is generated for all players. Fill in the grid so that every row, column, and 3×3 box contains the digits 1 through 9 exactly once.

Use the Notes button (or press N) to toggle pencil-mark mode for tracking candidates. Click a number to place it, or use your keyboard. Conflicts are highlighted automatically.

New to sudoku? The How to Play guide walks through your first puzzle step by step, and the Sudoku Tips page covers scanning habits and what to do when you’re stuck.
