Unlimited Zip-style puzzles
LinkedIn's Zip gives you one puzzle a day. If one isn't enough, Rill is the same kind of puzzle — one line through every cell, numbers in order — with levels that never run out. Free in your browser, no login, no ads in the browser.
The rules you already know
- Start at 1 and draw one line through every cell, each exactly once.
- Pass the numbers in order and finish on the last one.
- The line moves up, down, left or right and can't cross itself. Fences block it.
In Rill the grid is a field and the line is water: each cell is a plot to water, each number a well. Every level has exactly one solution — a solver checks each one before you see it.
Three ways to keep going
Ladder — levels that never run out
Start on a 4×4 grid and climb. Fields grow to 8×7 and keep coming, the same for every player, with ranks from Trickle to Ocean along the way. Your place is saved on your device.
Blitz — 90 seconds
As many small fields as you can solve against the clock. Every solve adds time.
Daily — one for everyone
Like Zip, there's also a daily puzzle that everyone gets, with a spoiler-free grid to share your time.
Questions
Is there an unlimited version of LinkedIn's Zip?
LinkedIn's Zip is one puzzle a day. Rill is an independent game of the same type with a Ladder that never runs out and a 90-second Blitz. It's free, plays in the browser and needs no account.
Is it free? Do I need to sign up?
Free, no account, no sign-in. The browser version has no ads. The iPhone and iPad app is free and supported by ads: none during your first puzzles, then a small banner below the field, and full-screen ads only between levels or after a Blitz run.
Any tips for harder levels?
Corners and dead-end cells are forced, never split the empty cells into two pockets, and keep a way into the last number. More in How to play Rill.
