Zip Puzzle Solver
Paste a screenshot of the Zip puzzle and get the path.
On iPhone: take a screenshot, tap the preview, choose Copy and Delete, then tap Paste. On a computer you can also press ⌘V / Ctrl+V or drop an image here.
How it works
Everything runs in your browser; the image is never uploaded. The page finds the grid lines and any walls, reads each number by comparing it with reference digits, then searches for the path from 1 to the last number that fills every cell, discarding any branch that can no longer reach the next number or that cuts off part of the board.
