Printable Expert Sudoku — 4 Per Page

Four freshly generated expert sudoku puzzles on one A4 or US Letter sheet — a multi-week solving ration in a single print. At forty-five to ninety minutes per typical expert puzzle, a full four-up sheet represents three to six hours of focused work. Not the layout for impatient solvers, but exactly right for the advanced solver who likes a stack of paper-based work waiting on the desk.

Expert at four-per-page is a stretch on cell width. The grids print at roughly seven to eight millimetres per cell — wide enough for the full 3×3 candidate notation that expert puzzles demand, but only just. Solvers who write very small candidate marks find this comfortable; solvers with broader handwriting often prefer the one-per-page layout for expert and reserve four-per-page for easier difficulties where less candidate notation is required. Try a sheet and see which side of that line you fall on — there is no harm in switching.

The four-puzzle batch suits the rhythm of expert solving naturally. Where easy and medium are dip-in-dip-out formats, an expert grid is usually a one-sitting commitment, and a four-up sheet gives you a clear sequence of four such sittings. Time-tracking solvers print the sheet on a Sunday and tick off one puzzle per evening across the week. Puzzle journalers like the format because each of the four IDs goes neatly into a record book. Travel solvers like it because the sheet folds into a notebook and survives a three-leg flight without battery anxiety.

Every puzzle on the printed sheet is uniquely solvable by logic at the same expert difficulty. The four puzzles are independent — generated from four different seeds — so there is no pattern repetition across the sheet. Each puzzle carries its own ID under the grid and a QR code in the corner; scan the code to load that specific puzzle in the on-screen solver if you want to verify a solution or pass the puzzle to a friend.

Four-per-page printable expert sudoku is free with no account gate, no per-day generation limit, and no watermarks on the sheet. The reproduction license permits free non-commercial use in classrooms, care homes, religious settings, and personal contexts. If you want a denser batch on one sheet, switch to six-per-page from the layout selector; if you prefer the largest possible cell size for full candidate notation, switch to one-per-page.

Four-per-page expert is the format we recommend for solvers who want a batch but value cell width — slightly more legible candidate notation than six-per-page, with twice the puzzles of one-per-page.
