Make your own Zip-style path puzzle — free.
Customize the grid size and number of checkpoints, then generate an original puzzle that has one checked solution. Play it, share a matching link with friends, or download a printable PDF with its answer key. No signup required.

More checkpoints usually provide more guidance, but overall solving difficulty also depends on the walls and route. The generated grid is not a manual wall editor.
Every generated puzzle is constrained to exactly one valid path. You can preview and solve it on the right before exporting.

How to create a number path puzzle
Step 1: Choose 5×5 for a compact challenge, 6×6 for a longer route, or 7×7 for a larger grid. Step 2: Choose 3–7 numbered checkpoints. Step 3: Click Generate new to make a random original board, or enter a seed to reproduce one. Step 4: Use Copy play link so others can open the same grid and checkpoint count, or Export PDF for a matching printable question and answer sheet.
How the puzzle is verified
Pathgrid generates a complete cell-by-cell route, places numbered checkpoints along that route, and adds blocking edges as needed. A bounded search checks whether more than one valid path remains. The board is made available for sharing or exporting only when the uniqueness check succeeds.
Can I choose the grid size and how many numbered squares appear?
Yes. The generator supports 5×5, 6×6 or 7×7 and any checkpoint count from 3 through 7. The seed and settings are included in the share URL, so your puzzle stays reproducible.
Can I place each wall and numbered square myself?
Not yet. This is a configurable automatic puzzle generator rather than a drag-and-drop level editor. It generates and verifies the layout based on your settings, which lets you make and print many original puzzles quickly.
Is this an official LinkedIn Zip puzzle maker?
No. This is an independent Zip-style number-path game maker with original deterministic boards, not a tool from or endorsed by LinkedIn.
Why unique solutions matter
Random paths alone can leave several possible solutions. A uniqueness check means the puzzle has one intended outcome and the printed answer sheet corresponds to that outcome.
Can I share and print puzzles?
Yes. Use Copy play link for a reproducible online generator board, or Export PDF for a printable sheet and answer page. You can also download larger free puzzle packs or practice unlimited puzzle boards.
