Zip Solver — place the numbers, get the path
Recreate your board: in Numbers mode each tap places the next checkpoint (1, then 2, and so on — tap a numbered cell to remove it and renumber); in Walls mode tap two neighbouring cells to toggle the wall between them. Solve draws the full path through every square.
How to use it
Numbers go in the order your board shows them — the tool numbers your taps 1, 2, 3… automatically, and tapping an existing number removes it (later numbers shift down to keep the sequence unbroken). Walls are the thick black segments between two squares: pick the Walls tool, tap the two cells either side, tap again to remove. Solve shows every cell's step number and the direction to walk. "No path" means a number or wall differs from the real board.
