Free Printable Medium Jigsaw Sudoku
A freshly generated medium jigsaw sudoku — irregular regions at the sweet-spot tier, ready to print.
Jigsaw SudokuFree printable medium jigsaw sudoku puzzles — the irregular-region variant at the difficulty most regular solvers prefer. Jigsaw rules: classic 9×9 sudoku (row and column uniqueness) with the 3×3 boxes replaced by nine irregularly shaped regions of nine cells each. The heavier borders on the printed sheet outline the regions.
Medium jigsaw is where the irregular shapes start to matter. Pointing pairs and naked pairs all transfer from classic, but a pattern that's obvious inside a 3×3 box can hide inside a long, snaking jigsaw region until you slow down. Sudoku247Online's region-aware verifier guarantees every printed jigsaw is uniquely solvable by pure logic — no guessing required, the deductions are all there.
Plan on fifteen to thirty minutes with pencil marks. Print full-page so the irregular borders stay crisp. Each sheet ships with a freshly generated region layout, so no two prints look the same. 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.
