Summary
Sudoku is a brain-teasing number puzzle where you fill a 9×9 grid so that every row, column, and 3×3 box contains the digits 1 through 9 — no repeats allowed! It’s like a numbers party where every digit gets an invite, but no one can show up twice in the same room.
Instructions
Download and print your Sudoku puzzle.
- The board is a 9x9 grid, divided into nine smaller 3x3 boxes.
- Some numbers are already filled in.
- Your goal is to fill in the empty spaces with numbers from 1 to 9.
- Each number must appear only once in every row, every column, and every 3x3 box.
- Use logic, not guessing — every puzzle has only one correct solution.
Tip: Start with numbers that are easiest to place, and use pencil so you can adjust as you go.
Variations
Color Sudoku
- Instead of numbers, use 9 different colors. Great for kids or just a fun twist on the original!
Diagonal Sudoku (X Sudoku)
- In addition to the regular rules, both main diagonals must also contain the numbers 1–9 without repeats.
Sudoku Race
- Print two copies of the same puzzle and race a friend to see who can solve it first!
Team Sudoku
- Work in pairs or small groups and take turns placing numbers — great for classrooms or family game night.
