Daily Sudoku

The Daily Sudoku serves up a brand-new, fully solved-and-verifiable puzzle every single day. Choose an easy, medium, or hard challenge and fill in the 9×9 grid so that every row, column, and 3×3 box contains the numbers 1 through 9 exactly once. Sudoku is a fantastic mental workout that improves logic, concentration, and pattern recognition. This version includes helpful features — you can pencil in candidate numbers, highlight mistakes so you never get stuck, and use hints when you need a nudge in the right direction. A stopwatch tracks your time so you can try to beat your personal best. Because each puzzle is generated for the date, everyone sees the same grid that day, which makes it fun to compare solving times with friends. It runs entirely in your browser with no downloads and no account. Your best times are saved privately, and the game is completely free. Clear your mind, pick a difficulty, and solve today's Sudoku.
