How to Play Sudoku
Sudoku is a logic-based number placement puzzle. The objective is to fill a 9×9 grid so that each column, each row, and each of the nine 3×3 boxes contains all of the digits from 1 to 9.
- Each row must contain the numbers 1-9 exactly once
- Each column must contain the numbers 1-9 exactly once
- Each 3×3 box must contain the numbers 1-9 exactly once
Use the number pad below the grid to fill in cells. Tap a cell to select it, then tap a number. Use hints if you get stuck!
