LinkedIn Zip
Draw a path that visits every cell and hits the numbers in order.
Tap or drag from checkpoint 1 to extend the path. Tap a path cell to truncate back. Walls block the line — find the only route that reaches every cell.
About LinkedIn Zip
LinkedIn Zip is a single-stroke path puzzle. You're given an N×N grid with a handful of numbered checkpoints scattered across it. The goal: draw one continuous, non-self-crossing path that visits every cell exactly once and passes through the checkpoints in numerical order.
Each puzzle ships with a hand-picked set of walls between cells — they exist purely to force exactly one valid path, so every puzzle has a single correct solution. On Ludingo we generate 1000 puzzles per difficulty, deterministically seeded so a shared URL opens the same board for everyone.
How to play
- Tap (or click) the cell marked 1 to start the path.
- Extend by tapping an adjacent empty cell — or hold and drag along the cells you want to add.
- The path must visit every cell exactly once and hit checkpoints 1 → 2 → 3 → … in order.
- Walls between cells block the path. Tap a cell already on your route to truncate back to it.
Questions about LinkedIn Zip
What are the rules of Zip?
Draw a single continuous path that visits every cell of the grid exactly once and passes through the numbered checkpoints in order (1, then 2, then 3, and so on). Walls between cells are impassable — they enforce a unique solution.
Does every puzzle have one solution?
Yes. The generator places walls until only one valid path remains. If you find a route that visits every cell and hits the numbers in order without crossing a wall, it's the one true solution.
How does difficulty work?
Easy is 5×5 with 4 checkpoints. Medium is 6×6 with 5 checkpoints. Hard keeps the 6×6 grid but adds 7 checkpoints, so you have to thread a more constrained order through the same space.
How does sharing a puzzle work?
Every puzzle has a stable id like easy_42 or hard_3 — share the URL and your friend opens the exact same board with the exact same walls. Solve times come back as a share-back challenge.
