Zip

Draw one line from 1 to the last number, through every cell, in order. Walls block the way.

How to play

1. Draw a single line that starts at 1 and ends at the highest number.
2. The line must pass the numbers in order: 1, then 2, then 3, and so on.
3. It has to visit every cell exactly once. No cell may be left empty.
4. Walls (thick lines between cells) cannot be crossed.
5. Drag from the head of the line to extend it. Drag backwards, or tap an earlier cell, to undo.

FAQ

Is this the LinkedIn Zip game?

No. It is an independent puzzle with the same rules. LinkedIn publishes one Zip a day; here you get a daily puzzle plus unlimited practice in three sizes. We are not affiliated with LinkedIn.

Does the line have to fill every cell?

Yes. A path that reaches the last number with cells left over is not a solution. Every puzzle here has exactly one path that works.
