🔢 This free printable sudoku prints on a single page. The answer key sits in a small strip at the bottom — fold it backward along the dotted line before you start, and you can solve honestly without ever seeing the solution. Suitable for ages 12+ — no special knowledge needed.
Fill the grid so every row, every column, and every 3×3 box contains the digits 1 through 9 exactly once.

How to Solve This Sudoku
Easy Sudoku puzzles like this one start with plenty of given numbers, which means you can almost always find your next move by logic alone — no guessing required.
Start with the fullest rows, columns, and boxes. The more numbers already filled in around a blank cell, the fewer candidates are left for it — often just one.
Scan for lone possibilities. If a row, column, and 3×3 box together already rule out every digit but one for a cell, that's your answer — no deeper technique needed.
Work in pencil for candidates. Jotting small candidate numbers in a cell's corner helps you spot when only one option survives after checking all three constraints.
This puzzle is built to be solvable through this kind of straightforward scanning alone. For the harder techniques you'll need once you move up in difficulty, see our complete Sudoku strategy guide.
About This Puzzle
