Printable Medium Mini Sudoku — 4 Per Page

Four freshly generated medium mini sudoku puzzles — 6×6 grids — on a single A4 or US Letter sheet. Medium 6×6 takes five to ten minutes per puzzle, so a full four-up sheet represents twenty to forty minutes of solving in print. The right format for an afternoon coffee break, a long commute, or a quiet evening where four short puzzles outperform one long one.

The four-per-page layout for medium 6×6 works particularly well because the underlying grid is small. Cell widths print at roughly twelve to fourteen millimetres per side, which is significantly more generous than the four-per-page 9×9 layout. That extra cell width matters at medium difficulty, where light pencil marks (one to three candidate digits per cell) start to be useful. The format gives you room for the marks without forcing a switch to one-per-page.

Who prints medium 6×6 at four-per-page? Solvers who want a multi-puzzle session at a difficulty that requires real thinking but not a long time commitment. Commuters print these for the train. Office workers print them for lunch breaks. Puzzle clubs at the intermediate level use them as a uniform set for a small group. The four-distinct-seed property means no two puzzles on the sheet are the same, even though they share difficulty.

Medium 6×6 reuses the techniques you would deploy on a medium 9×9 — hidden singles, naked pairs, locked candidates — but the rectangular 2×3 box geometry of the 6×6 grid changes the way some of those patterns appear. The eliminations propagate faster on a smaller grid, which means each move resolves a higher fraction of the puzzle than the same technique would on a 9×9. Useful for solvers building fluency in intermediate techniques.

Every puzzle on the sheet is uniquely solvable by logic. Each carries its own puzzle ID and a corner QR code linking to the same puzzle in the on-screen solver.

Switch to six-per-page for a denser layout or one-per-page for a full-size single-puzzle format.

Medium 6×6 at four-per-page is a particularly good format for learning intermediate techniques. The smaller grid means each elimination resolves more of the puzzle, so the feedback loop from move to next move is faster than on a 9×9. Solvers who want to internalise hidden singles and naked pairs often work through a batch of four medium 6×6 puzzles in a single sitting — long enough to see the patterns repeat, short enough that fatigue does not set in before the techniques stick.
