Printable Medium Mini Sudoku — 6×6

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.
