A calm sudoku. Fresh daily puzzle, no timer pressure, no ads, auto-saves. Pick a difficulty.
A fresh single daily puzzle is the difference between a tool you use once and a habit you keep. There's exactly one puzzle today. Everyone playing it is solving the same board. Tomorrow there's a new one. Miss it and you missed it — there's always tomorrow.
This sudoku is built for calm: pale teal palette, no flashing ads, no popups asking you to upgrade. Mistakes are gently flagged in red but the puzzle never punishes you with a timeout. Auto-saves every move — close the tab, come back, pick up exactly where you left off. Three hints per puzzle if you get stuck. Pencil mode (📓) for tentative marks.
Easy puzzles open with ~36 clues, medium ~30, hard ~24 — all generated server-side by a backtracking solver that guarantees a unique solution.
You probably need quiet focus time. Some workplaces protect it. We track 122 of them.
