6×6 Sudoku
A 6 × 6 grid split into six boxes of 2 rows by 3 columns. Fill every row, column and box with the numbers 1 to 6.
How to play
- Tap or click a square, then tap a number or type it on your keyboard. Arrow keys move around the grid.
- Fill the grid so every row, every column and every box contains each number from 1 to 6 exactly once.
- Turn on Notes to pencil in numbers you’re considering. If a number clashes with another in its row, column or box, it turns red.
- Stuck? Undo a move, or press Hint to fill in one correct square. Your progress is saved if you leave the page.
What it practises
- Logical reasoning
- Scanning rows, columns and boxes
- Using notes to keep track of possibilities
Level: Ages 7–10 (Grades 2–5)
Tips for 6×6 Sudoku
The boxes are wider than they are tall (2 rows by 3 columns), so check each box carefully.
Pick a number, like 6, and find every box that still needs it. Often only one square can take it.
Questions and answers
How is 6×6 Sudoku different from 9×9?
It uses the numbers 1 to 6 and has six boxes of 2 × 3 squares instead of nine 3 × 3 boxes. The rules are the same, but there’s less to keep track of.
Is 6×6 Sudoku good for beginners?
Yes. It’s a good bridge between 4 × 4 Sudoku for young children and full 9 × 9 Sudoku, and every puzzle here can be solved without guessing.
How many numbers are given at the start?
Each 6 × 6 puzzle starts with 14 of its 36 squares filled in, and has exactly one solution.
