Printable Master Sudoku — 4 Per Page

Four freshly generated master sudoku puzzles on a single A4 or US Letter sheet — a multi-week batch for the advanced solver who lives between expert and evil. Master grids typically run sixty to ninety minutes per puzzle, so a full four-up sheet is four to six hours of focused work. The right layout for a vacation that overlaps with bad weather, or for the solver who likes a paper-based work-in-progress waiting on the desk.

Master puzzles need the full nine-candidate notation in most empty cells before the solve opens up, and the cell width on a four-per-page sheet (around seven to eight millimetres per side) is the lower bound for this kind of dense pencil-mark workflow. Solvers with small, precise handwriting find this comfortable; solvers who prefer larger pencil marks often print master at one-per-page and use the four-up sheet for easier difficulties. Either way, the puzzles themselves are identical to the one-per-page variant — only the print size differs.

Four-per-page master is also the format puzzle clubs reach for when they want a uniform set distributed to four solvers at the same difficulty. The four grids on the sheet are independent, drawn from four different seeds, and arranged so each can be cut out and handed off without losing context. Each puzzle prints with its ID number and a QR code that links to the same puzzle in the on-screen solver — handy for verifying a solution at the end of a club session or passing a puzzle mid-solve.

Master grids reuse the techniques you already know from expert — X-wing, swordfish, hidden triples, XY-wing — but combine them in longer chains and tighter eliminations. A four-up batch lets you build pattern recognition across multiple grids without resetting the difficulty between solves. Time-tracking solvers find this useful: the master tier is where individual solve times vary the most based on which specific patterns appear, and a four-puzzle batch averages out the noise.

Four-per-page printable master sudoku is free, with no account gate, no per-day download limit, and no watermarks on the sheet. The license permits free reproduction for personal, classroom, care home, religious-community, and other non-commercial settings. Refresh the page for a new four-puzzle batch at the same difficulty. Switch to six-per-page for a denser layout (less cell width per grid) or one-per-page for the largest possible cell size.

For most advanced solvers the four-per-page master layout is the practical sweet spot — a meaningful batch on one sheet without the cell-width compromise that six-per-page introduces at this difficulty.
