Daily Brain Challenge
Monday, November 2, 2026Medium
Today's 9×9 Sudoku is the same for everyone and changes at midnight (your local time). Solve it to keep your streak alive. Your time and streak are stored only in this browser.
How the daily challenge works
Each day we generate one Sudoku from that day's date, so every visitor gets an identical puzzle with a single valid solution. Fill every row, column and 3×3 box with the digits 1 to 9.
- Streaks: solve on consecutive days to grow your streak. Missing a day starts it again from one.
- Hints: you can use them, but solving without hints counts towards the “Unassisted” achievement on Hard Sudoku.
- Fair play: there is no public leaderboard, so there is nothing to gain by rushing. Play for the satisfaction.
