Easy Sudoku

How to play

Easy grids start with 38 givens. Most cells can be found by scanning a row, column or box for the one digit that is missing.

1. Fill every row, column and 3×3 box with the digits 1 to 9, each used once.
2. Tap a cell, then tap a number. On a computer you can type digits and move with the arrow keys.
3. Switch on Notes (or press N) to pencil in candidates. Placing a digit clears it from the notes in the same row, column and box.
4. Repeated digits turn red straight away. Check marks any cell that differs from the solution; Hint fills one cell for you.

Tips for easy grids

• Look for a row, column or box that already has eight digits.
• Pick one digit, say 5, and scan where it can still go in each box.

About sudoku

Sudoku is a logic puzzle played on a 9×9 grid divided into nine 3×3 boxes. The goal is to fill every row, every column and every box with the digits 1 to 9, each exactly once. Some digits, called givens, are already placed, and the fewer givens a grid has, the harder it usually is.

The modern puzzle first appeared as “Number Place” in Dell Magazines in 1979 and is credited to the American puzzle maker Howard Garns. The Japanese publisher Nikoli popularised it in the 1980s and gave it the name Sudoku.
