How to Play Easy 6x6 Sudoku

Fill the grid so that every row, every column, and every 2×3 box contains the digits 1 through 6 exactly once. The boxes are rectangles — two rows tall and three columns wide — marked by the thicker lines after row 2, row 4, and column 3. Start with the rows, columns, and boxes that already hold the most digits: where only one digit is missing, it places itself. That technique, the obvious single, carries you through most 6×6 puzzles.

If 6×6 still feels like a stretch, warm up on 4×4 Mini Sudoku first — it teaches the same rule on a smaller board and is the format we recommend on our Sudoku for Kids page. And when hard 6×6 stops slowing you down, take the leap to a full easy 9×9 Sudoku — the logic is identical, just bigger.

Frequently Asked Questions — Easy 6x6 Sudoku

How many clues does an easy 6x6 Sudoku have?
Our easy 6×6 puzzles start with around 22 of the 36 cells already filled. With that many givens, most rows, columns, and 2×3 boxes are missing only one or two digits, so you can solve the whole puzzle by simple scanning and elimination.
What is the best way to start an easy 6x6 Sudoku?
Look for rows, columns, or boxes that are already nearly full. If a row contains five of the six digits, the empty cell must hold the missing one. These obvious singles are usually enough to finish an easy 6×6 from start to end.
How long does an easy 6x6 Sudoku take?
Most players finish an easy 6×6 in two to four minutes. It is noticeably more substantial than a 4×4 Mini puzzle but still far quicker than a 9×9 grid — ideal for a short break or a daily warm-up.
Is easy 6x6 Sudoku good for beginners?
Yes. If you have never played Sudoku, start with 4×4 Mini Sudoku to learn the rule, then move here. Easy 6×6 introduces the rectangular 2×3 box without overwhelming you with candidates.
