Daily Sudoku
A fresh Sudoku puzzle every day. Easy, medium and hard variants — same puzzle for everyone, so you can compare your time. Use the keyboard (arrow keys to move, 1-9 to place, backspace to erase) or tap.
How to play
Fill every row, column and 3×3 box with the digits 1-9 — no repeats. Tap a cell to select it, then tap (or press) a number to place it.
Use Pencil mode to jot small candidate marks in cells you're still thinking about. Press Hint to fill the selected cell with the correct value. Reset clears your work and starts the timer over.
Conflicts (a number that breaks a row, column or box) appear in red. Cells matching your selected value are highlighted to help spot patterns.
