Same board for each date
All players in the same mode and on the same date receive the same difficulty and the same Sudoku board.
One fixed board each day for every player. Complete it to save your score, build a streak, and compare results.
Jump to the board9×9 Sudoku board. Use the arrow keys to move between cells; Home and End go to the start or end of a row; Ctrl or Command + Home/End goes to the first/last cell on the board. Keys 1–9 enter a digit in the current mode; Shift + 1–9 adds a quick Note without turning Notes on; 0, Delete, or the numpad decimal key clears a cell; N toggles Notes, A toggles Auto Candidates, and Space pauses the game.
Select an empty cell to see valid candidates.
Auto candidates and Notes mode are remembered separately for Classic and Killer. Pause state and game progress are not synced as preferences.
All players in the same mode and on the same date receive the same difficulty and the same Sudoku board.
Each attempt is recorded separately, but the daily leaderboard keeps only the best result by score and then time.
A game opened before midnight is still submitted to the previous date. After that, you can switch to the new day's challenge.
