How to play Sudoku

1. Fill every empty square with a number from 1 to 9.
2. Each row has every number once.
3. Each column has every number once.
4. Each of the nine 3×3 boxes has every number once.

Tap a square, then tap a number below the board. Turn on Notes to pencil in the numbers a square could still hold. On a keyboard, type a digit; Shift plus a digit writes a note. Every puzzle has one answer, and you can reach it by logic alone, no guessing.

Want another one? Play an easy sudoku, a medium sudoku or a hard sudoku, or start small with a 4×4 and a 6×6.
