Zip Unlimited
This is Zip with no daily limit: tap New and the board below deals a brand-new path puzzle, as many as you want, free. Draw a single line that visits the numbered checkpoints in order, 1 → 2 → 3 and on, and fills every cell on the grid along the way. Every board is generated fresh and has exactly one path that works.

Endless boards, two sizes
The puzzles here are generated on demand, so New always has another board ready — no daily cap and nothing to wait for. Play one or play a dozen.
Above the grid you can switch size. 5×5 is the place to learn the corner-first, fill-everything rhythm, with the whole path in view. 6×6 — the classic Zip size — leaves longer stretches between checkpoints, so keeping the unused area connected matters much more.
How to solve it
Start in the corners. A corner cell has only two neighbours, so the path through it is nearly forced — and since the line must cover every cell, corners are the safest place to commit.
Never strand a cell. The moment your line cuts the empty area into two pieces, one of them is unreachable and the board is dead. Before drawing, glance at what the line leaves behind.
Work between checkpoints. The stretch from 3 to 4 has a fixed number of cells to absorb; if the direct route is too short, the detour has to go somewhere, and there are usually only one or two places it can go.
Prefer one a day — or a different path puzzle?
Tap Daily on any board for the shared puzzle of the day, the same one everyone else is solving, with a streak to keep. Then come back here when one is not enough.
For more single-line logic, Masyu routes a loop through white and black pearls, and Slitherlink builds one closed loop from numbered clues. Both run on the same fair-by-design principle: one solution, always reachable without guessing.
Zip Unlimited: FAQ
Is Zip unlimited here?
Yes. Boards are generated on the spot, so tapping New deals a brand-new puzzle as many times as you like, at either size. No daily cap, no sign-up.
What are the rules of Zip?
Draw one continuous line that passes through the numbered cells in ascending order and covers every cell on the grid exactly once.
Does the line have to fill the whole grid?
Yes — every cell must be part of the path. That is what makes stranding an empty cell fatal, and why corners are the safest place to start.
Is there still a daily Zip?
Yes — tap Daily on any board for the shared puzzle of the day, identical for every player.
Do I need an account?
No. It plays free in the browser on phone, tablet and desktop, with no download and no sign-up.
