Make a printable maze puzzle

The job

Printed maze packs repeat themselves; a generator gives a fresh one every time at exactly the difficulty a grid size implies — more cells, longer path.

Generate it

Set columns and rows — 20×14 is a comfortable sheet — and generate. The maze is a perfect maze: entry top-left, exit bottom-right, exactly one route between any two cells.

• Show solution overlays the unique shortest path — print it separately as the answer key.
• Bigger isn't just harder: a 60×40 maze is also a pain to print at A4.

Worked example

30×20 cells at 20 px each fills an A4 landscape PNG nicely for a worksheet. For a little kid, drop to 10×8 — the same rules but a puzzle solvable in a minute.

Limits

2–100 cells per side and 10,000 cells total. PNG download or direct print; the rendering is monochrome because it has to survive any printer.
