Printable Medium Mini Sudoku — 6×6
A medium 6×6 puzzle — compact but challenging enough to make you think.
Free printable medium mini sudoku puzzles — 6×6 grids at a difficulty that bridges quick solving and real technique. Medium 6×6 ships with roughly sixteen to eighteen given numbers out of thirty-six cells, fewer than easy, which means scanning alone is not enough — you will need to spot hidden singles, light naked pairs, and the occasional locked-candidate elimination across the rectangular 2×3 boxes that define the 6×6 format.
Medium at 6×6 takes about five to ten minutes per puzzle for most solvers. That solve time makes it the natural format for the in-between moments of a day — a coffee break that runs slightly longer than usual, a waiting room stretch, the gap between train stops. The full puzzle fits comfortably in the upper portion of a printed sheet, leaving room for any solving notes you want to keep in the margin.
The technique landscape at medium 6×6 is a scaled-down version of the medium 9×9 experience. The same fundamental techniques apply — hidden singles, naked pairs, pointing pairs across the rectangular boxes — but the smaller grid means each move resolves more of the puzzle proportionally, and the path to the unique solution is correspondingly shorter. This is a useful difficulty for solvers building fluency in mid-tier techniques without committing to a full 9×9 medium solve.
Who prints medium 6×6? Solvers who finished the easy 6×6 set and want a step up at the same grid size. Parents looking for a puzzle their early-teen child can attempt without frustration. Commuters who want something more demanding than easy but shorter than a full classic. Anyone with the kind of attention span that finds a medium 9×9 too long and an easy 6×6 too quick.
This page generates one fresh medium 6×6 puzzle per A4 or US Letter sheet at a comfortable print size. Refresh for a new puzzle at the same difficulty. Switch to four-per-page or six-per-page from the layout selector if you want a denser batch — useful for classroom sets or for solvers who like to print a week of medium minis at once.
Every puzzle is uniquely solvable by logic, no guessing required at any step. The reproduction license permits free non-commercial use; no account, no per-day limit, no watermarks. When medium 6×6 feels routine, step up to hard 6×6 at the same grid size — the hardest difficulty available at this format — or graduate to the classic medium 9×9 for a longer challenge.
Frequently asked questions
Quick answers about printing sudoku from Sudoku247Online.
- What is mini sudoku?
- Mini sudoku uses a 6×6 grid divided into six 2×3 boxes. Each row, column, and box must contain the numbers 1–6 exactly once. It's the same logic as classic sudoku, just smaller.
- Who is 6×6 mini sudoku for?
- Mini puzzles suit kids learning the rules, casual solvers who want a 3–7 minute fix, and anyone using sudoku for a short mental break. They're popular in classrooms for warm-ups.
- How long do mini sudokus take?
- Easy mini puzzles take 2–5 minutes for most solvers; hard mini takes 7–12 minutes. They're meaningfully quicker than full 9×9 puzzles at the same difficulty label.
- Can I print mini sudokus for a classroom?
- Yes — they're great for ages 6–10 and for warm-up activities. The 6-per-page layout fits six mini puzzles on one A4 or Letter sheet — ideal for a class set.
- Are mini puzzles solvable without pencil marks?
- Easy and medium mini puzzles are usually solvable by scanning alone. Hard mini benefits from pencil marks even though the grid is small.
- Are these the same as 4×4 sudoku for kids?
- No — 4×4 kids sudoku uses four 2×2 boxes with the numbers 1–4. Mini is the next step up: 6×6 with numbers 1–6, suitable for slightly older or more experienced kids.
