Hold on 1, then draw through every cell in number order.
Why Zip Is a Perfect Micro-Break
Zip is a quiet logic puzzle: one path, every cell, numbers in order. It takes a few minutes, rewards planning ahead, and feels satisfying when the final cell clicks into place — without noise or accounts.
What Is Zip?
Zip is a grid path puzzle (a Hamiltonian path with ordered checkpoints). You start at 1 and draw a continuous line that fills the whole board while visiting each numbered cell in sequence. Harder boards add walls you cannot cross — the same rule set popularized by LinkedIn’s daily Zip game.
How to Play Zip
- 1
Start on 1
Press and hold the cell marked 1, then drag. The path always begins there.
- 2
Fill every cell
Visit each square exactly once using up, down, left, or right moves — no diagonals.
- 3
Hit numbers in order
Pass through 2, then 3, then 4… You cannot enter a higher number early.
- 4
Respect walls
On Medium and above, bold walls block edges. Route around them.
- 5
Use Undo, Hint, Clear
Undo steps back one cell. Hint trims mistakes and reveals the next correct step. Clear wipes the path on the same puzzle.
Strategy Tips
Treat numbers as anchors
Solve segment-by-segment between consecutive numbers instead of the whole board at once.
Watch dead ends
Never seal off an unvisited region with only one entry — fill it before you close the door.
Use walls as constraints
Walls reduce options. Identify forced corridors early; they often decide long stretches of the path.
Backtrack freely
Dragging back along your line erases steps. Experiment without restarting the whole puzzle.
Daily vs practice
Daily uses a fixed seed for the calendar day so everyone shares the same board. Practice generates fresh boards anytime.
