The short version

Daily Sudoku is free, plays in your browser with no account, and refreshes every day at midnight US Eastern. Pick a difficulty, the clock starts when you do, and your time is your score. Play today’s Sudoku.

01 How daily Sudoku works

Sudoku is a 9x9 grid split into nine 3x3 boxes. The rule is simple: every row, every column, and every box must contain the digits one through nine with no repeats. A handful of digits are given to start, and the rest is pure deduction. Tap a cell and type a number; switch on Notes to pencil in the candidates you are still weighing, and the grid flags a conflict when a number breaks the rules.

02 Free, and new every day

Like every game here, daily Sudoku is free, needs no account, and works on your phone or desktop with nothing to download. A fresh set of puzzles is published each day, the same grids for everyone, and they reset at midnight US Eastern. The timer only runs while you are playing and pauses when you step away, so your score reflects solving, not interruptions.

03 A difficulty for everyone

Every day ships four separate puzzles: Easy, Medium, Hard, and Very Hard. Easy is a gentle warm-up you can clear over coffee; Very Hard asks for the trickier chains and forces you to slow down. They are timed independently, so you can race your own best Easy time or settle in for a long Very Hard solve. For more deduction after you finish, try our other daily logic puzzles or the star-battle forest of Shrooms, and browse the full lineup on the Greatest Games homepage.
