6×6 Sudoku — balanced flow
Place 1–6 once per row, column, and 2×3 box. A medium-sized board that usually takes 3–8 minutes — ideal for practicing techniques in shorter sessions.
Why pick 6×6
- A balanced step between mini and classic Sudoku
- Finishes in 3–8 minutes — fits commutes and lunch breaks
- Great for learning Locked Candidates and Naked Pairs
- Builds confidence before tackling full 9×9
Who it's for
Choose 6×6 when 4×4 feels too short but you don't want to commit to a long 9×9 round, or when you're practicing techniques in bite-sized sessions.
6×6 Sudoku rules
Each row and column contains 1 through 6 exactly once, and each box is 2×3. It is smaller than 9×9 but still asks you to cross-check rows, columns, and boxes.

6×6 solving tips
- Count missing digits in each 2×3 box before scanning the whole board.
- If candidates in a box all sit on one line, remove that candidate from the rest of the line.
- Use notes once cells have only two candidates; 6×6 is where technique practice starts to pay off.
