How a number-path puzzle works

Start on 1 and drag. Visit the numbered checkpoints in order, pass through every cell exactly once, never cross a wall, and finish on the highest number. Drag back over your own path to undo. There is exactly one solution to every grid here — the generator proves it before the puzzle ships, so you are never guessing.

Sizes run easy 5×5, medium 6×6, hard 7×7. If you know this format as the one-line or Zip-style puzzle, this is that, with a fresh grid every day.
