Zipper - Connect the Numbers

120 hand-crafted puzzles. No ads, no sign-ups, no internet - just one line to draw through every cell.

How fast can you crack the path?

Zipper is a beautifully simple one-line puzzle: draw a single unbroken path that connects the numbers in order and fills every square on the board. Sounds easy? The walls, the corners and the clock will test you.

Trace from 1 to 2 to 3 and beyond, winding through every cell exactly once. No square left empty, no line crossing itself, no wall in your way. When the whole grid lights up, you've cracked it.
