How does the pack builder work?
Everything happens on your device. When you press Generate, your browser creates each Jigsaw Sudoku grid from the pack seed, solves it to make the answer key, and lays the pages out as a PDF. Nothing is uploaded and there’s no account. Four 4×4 or 6×6 grids share a sheet, and two 8×8 or 9×9 grids share a sheet. Tick Large print if you want one big grid per page. 4×4 comes in easy, 6×6 in easy and medium, and 8×8 and 9×9 in easy, medium and hard. Each puzzle prints with its number and seed, so answers line up even when you keep them in a separate PDF. The same seed and settings always give the same puzzles. Use Copy share link to send a class or a friend the exact same pack, or press shuffle for a fresh set.

About these Jigsaw Sudoku packs
Print a Jigsaw Sudoku pack and solve it with a pencil. Jigsaw Sudoku, also called Irregular Sudoku, is a sudoku whose boxes are replaced by regions of different shapes. Every row, every column and every heavy-bordered region holds each digit once. Each file is a black and white booklet: the puzzles come first with the givens in bold, and the answer key starts on its own page with every cell filled and the region walls still drawn. Packs are split by size and difficulty: 4×4 at easy, 6×6 at easy and medium, and 8×8 and 9×9 at easy, medium and hard. A 4×4 or 6×6 sheet holds four puzzles, and an 8×8 or 9×9 sheet holds two. Seeds are fixed, so the same download always has the same grids. Each single pack has eight puzzles, and the starter pack has one puzzle from each of the nine packs. To try one grid on screen first, open Jigsaw Sudoku and use Print or Download PDF there.
