Free Printable Expert Jigsaw Sudoku
A freshly generated expert jigsaw sudoku — the hardest tier, irregular regions, full A4 sheet.
Jigsaw SudokuFree printable expert jigsaw sudoku puzzles — the deepest irregular-region workout we generate. Jigsaw rules: classic 9×9 sudoku (row, column) plus nine irregularly shaped regions of nine cells each.
Expert jigsaw ships with 29–32 givens. Almost every placement comes from technique — swordfish, XY-Wing, Unique Rectangle, and chains all appear, often forced through the irregular region geometry rather than the rectangular 3×3 boxes you'd see in classic expert. Expect 40–80 minutes for a clean solve, sometimes split across two sittings.
Sudoku247Online runs every expert jigsaw through the same region-aware uniqueness checker as the lower tiers — the answer is always pinned to a single legal solution, no guessing required. Print full-page so the regions and pencil-mark space have room. Each sheet ships with a freshly generated region layout, so no two prints look alike. Free, no account, no watermark, freshly generated every load.
Frequently asked questions
Quick answers about printing sudoku from Sudoku247Online.
- What is jigsaw sudoku and how does it differ from classic?
- Jigsaw sudoku uses the same 9×9 grid as classic, but the nine 3×3 boxes are replaced by nine irregularly shaped regions of nine cells each. Each region still must contain the digits 1–9 exactly once; row and column rules are unchanged. The heavier borders on the printed sheet outline the irregular regions.
- Are the regions the same on every printed puzzle?
- No — Sudoku247Online generates a fresh region layout for every printable jigsaw. Two puzzles printed back-to-back will have different region shapes, which keeps every solve genuinely new.
- How do I read the region borders?
- Every cell belongs to exactly one region. The borders between cells in different regions are drawn heavier than the borders between cells in the same region — trace the heavy lines with your eye to see each nine-cell region as a connected shape.
- How long does a jigsaw sudoku take to solve?
- Easy jigsaw takes 10–20 minutes, medium 15–30, hard 25–50, expert often 40–80 minutes. The irregular regions make box-based scanning slower at first; the time settles down once the region shapes feel familiar.
- What techniques are essential for jigsaw sudoku?
- Naked singles and hidden singles work identically to classic — they just operate on irregular regions instead of 3×3 boxes. Pointing pairs, naked pairs, and X-Wing also transfer directly. Box-line reduction adapts naturally once you treat each irregular region as the unit. See /strategies for technique guides.
- Are the solutions printed with the puzzle?
- Not on the standalone jigsaw printables yet — solving online at /jigsaw-sudoku reveals the solution on completion. A 'Print with solutions' option for jigsaw is on the roadmap alongside the killer follow-up.
