Free maze generator: print or play online

Tricks for any maze

Every maze made here has a way through, and with "Just one" picked there's exactly one.

• Keep one hand on the wall. Follow the left (or right) wall and never let go. In a maze with no loops, it always gets you out, even if it's the long way round.
• Work backwards. Start at the finish and trace back towards the start. Mazes are often easier in reverse.
• Fill in the dead ends. On paper, shade every dead end back to the nearest junction. What's left is the path.
• Stuck? Press Solution to see the way, or Start again to have another go.

Your own maze generator

You'll describe it to a free AI assistant, paste what it writes into a file, and open it in your browser. No coding needed.

Build it in five steps

Step 1 gives you a simple version that works, and each step after it adds more. Yours will look a bit different from the one above, because the AI writes its own version each time.

1. Ask for the maze generator

   Copy this prompt into your AI assistant:

   Copy this promptCopy

   I don't know how to code. Please make me a maze generator that runs in a web browser.
   
   Requirements:
   - ONE single HTML file (HTML, CSS and JavaScript together), no external libraries, no internet needed. I will save it and double-click it.
   - Draw a square maze as an SVG picture, with dark walls on a white background.
   - Make the maze with the "depth-first search" (recursive backtracker) method, so every square can be reached and there is exactly one way through.
   - Buttons for the size: Easy (10 by 10), Medium (16 by 16) and Hard (26 by 26), and a "New maze" button.
   - Leave a gap in the top-left wall for the start and in the bottom-right wall for the finish.
   
   Please give me the complete file in one code block, then tell me in simple steps how to save and open it.

   Copy the code, paste it into your text editor and save it as maze.html. Double-click it and press New maze a few times.

2. Make it playable

   Copy this promptCopy

   That works, thank you. Please make it playable:
   - Put a mouse emoji at the start and a cheese emoji at the finish.
   - Let me drag along the paths with my finger or mouse, drawing a pink line behind me. I can only move through gaps, never through walls. Going back over my line rubs it out.
   - The arrow keys move one square at a time too.
   - Stop the page scrolling while I drag on the maze on a phone.
   - Start a timer on the first move, and when I reach the cheese show "You made it in 0:42!".
   Send me the complete updated file.

   Always ask for the complete file. Replace everything in maze.html, save, and refresh the tab (F5 or Cmd+R).

3. Add the solution and printing

   Copy this promptCopy

   Please add:
   - A "Solution" button that draws the way through in green, and hides it again.
   - A "Print" button that prints the maze in black and white, as big as fits on one A4 page, with a title and a "Name: ____" line, then the same maze with the solution on a second page.
   Send me the complete updated file.

4. Add circle and heart shapes

   Copy this promptCopy

   Please add a Shape choice:
   - Square (what we have now).
   - Circle: rings of rooms around a centre room, with more rooms in the outer rings so they stay about the same size. Start at the outside and finish in the middle.
   - Heart and Star: draw the shape on a hidden canvas, keep only the squares whose middle is inside the shape, and make the maze in those.
   Make the maze code work on a list of rooms and which rooms are next to each other, so every shape uses the same maze-making and playing code. Send me the complete updated file.

   This is the hardest step. If a shape comes out broken, paste the problem back to the AI in plain words, such as "the circle maze has walls missing in the middle ring".

5. Add a name maze and a dark mode

   Copy this promptCopy

   Please add:
   - A "Your name" shape: type a name, draw it in big bold capitals on the hidden canvas with a bar along the bottom that joins the letters up, and make the maze inside the letters.
   - A "Play in the dark" switch where you can only see the maze in a small circle of torchlight around you.
   - A choice of "Long and winding" paths or "Lots of dead ends" (grow the maze from a random room instead of the newest one).
   Send me the complete updated file.
