How does the pack builder work?
Everything happens on your device. When you press Generate, your browser creates each Renzoku 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 is no account. Four 4×4, 5×5, 6×6, or 7×7 grids share a sheet. Two 8×8 or 9×9 grids share a sheet. Tick Large print if you want one big grid per page. Every size from 4×4 through 9×9 comes in easy, medium, and hard. The range is Easy → 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 Renzoku packs
Print a Renzoku pack and solve it with a pencil. The board is a square. Each row and each column holds the digits 1 through N once, where N is the side of the grid. A dot drawn in the gap between two cells means those two digits are consecutive, one apart. An empty gap is a rule as well: no dot means NOT consecutive. The ends do not wrap around, so 1 and N are not consecutive. A 1 beside an N is allowed only when no dot is drawn there. Givens are printed in a heavier face and stay as they are. Empty cells are yours to fill. Pencil notes are not printed. The answer key writes every digit in a regular face and keeps every dot, so you can check both the numbers and the gaps. Each file is a black-and-white booklet. Puzzle pages show the givens and the dots. The answer key starts on its own page. Packs cover 4×4 through 9×9, each at easy, medium, and hard. The starter badge reads Easy → Hard, because every shipped size has all three difficulties. A 4×4, 5×5, 6×6, or 7×7 sheet holds four puzzles. An 8×8 or 9×9 sheet holds two. Tick Large print for one big grid per page. Seeds are fixed, so the same download always has the same grids. Each single pack has eight puzzles, and the starter pack has 18 puzzles, one of every size and difficulty that ships. The daily puzzle is 5×5 easy. To try one grid on screen first, open Renzoku and use Print or Download PDF there.
