Draw one line from 1 to the last number, through every cell, in order. Walls block the way.
Rules
- Draw a single line that starts at 1 and ends at the highest number.
- The line must pass the numbers in order: 1, then 2, then 3, and so on.
- It has to visit every cell exactly once. No cell may be left empty.
- Walls (thick lines between cells) cannot be crossed.
- Drag from the head of the line to extend it. Drag backwards, or tap an earlier cell, to undo.
Strategy tips
- Corners and dead ends first: a cell with only one open neighbour must be an end of the line, so the path has to enter and leave everything else in one sweep.
- Count the cells between two consecutive numbers; the line has to use exactly that many, so a long gap means a long detour.
- Walls usually force a U-turn. Look for the pocket a wall creates and work out which way the line sweeps through it.
- If a region can only be entered through one cell, the line must go in and come out through the same neighbourhood: plan the whole sweep before drawing.
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.
