Maze Generator

Welcome to the Maze Generator, a powerful tool for creating unique, solvable mazes instantly. Whether you need mazes for puzzles, games, education, or print materials, this generator offers full customization of size, entry/exit points, colors, and export formats.

Key Features

• Custom Dimensions: Create mazes from 5×5 to 101×101 cells. Odd dimensions recommended for optimal structure.
• Flexible Entry/Exit: Place start and end points at corners or random positions along any edge.
• Guaranteed Solvable: Every maze has at least one solution path from start to end.
• Color Customization: Personalize walls, paths, markers, and solution line colors.
• Multiple Export Formats: Download as PNG (raster), SVG (vector), or animated GIF (solution visualization).
• Animation Controls: Adjust GIF dimensions and animation speed for optimal file size and quality.

How It Works

Why Odd Dimensions?

The DFS algorithm operates on a grid where cells and walls alternate. Odd dimensions (11, 21, 31, etc.) ensure proper wall placement around the maze perimeter and produce cleaner maze structures. If you enter an even number, it will automatically adjust to the next odd value.

Usage Instructions

1. Set maze Width and Height using presets or custom values (5-101, odd recommended).
2. Select Start Point and End Point locations from corners or edges.
3. Customize Colors for walls, paths, markers, and solution line.
4. Optionally configure GIF Width and Animation Speed in advanced settings.
5. Click Generate Maze and view results in the tabbed output section.
6. Download your maze in PNG, SVG, or animated GIF format.

Export Format Guide

• PNG: Raster image ideal for printing and web use. Fixed resolution based on cell size.
• SVG: Vector format that scales perfectly to any size without quality loss. Best for large prints.
• Animated GIF: Shows the solution path being drawn step-by-step. Great for presentations and sharing.

Frequently Asked Questions

What algorithm does this maze generator use?

This maze generator uses the Depth-First Search (DFS) algorithm with recursive backtracking for maze generation, which creates perfect mazes with exactly one path between any two points. For solving, it uses Breadth-First Search (BFS) to find the shortest path between start and end points.

Why are odd dimensions recommended for mazes?

Odd dimensions (like 21x21) are recommended because the DFS algorithm works on a grid where cells and walls alternate. Odd dimensions ensure proper wall placement around the maze perimeter and create cleaner maze structures. Even dimensions are automatically adjusted to the next odd number.

What image formats can I download the maze in?

You can download mazes in three formats: PNG (raster image, good for printing), SVG (scalable vector graphics, perfect for any size), and animated GIF (shows the solution path being drawn step by step). Each format has specific use cases depending on your needs.

Can I customize the colors of the maze?

Yes, you can fully customize five color elements: wall color (maze barriers), path color (walkable areas background), start point color (entry marker), end point color (exit marker), and solution path color (the line showing the route through the maze).

What affects the GIF file size and animation speed?

GIF file size is affected by maze dimensions, target width setting, and animation speed profile. Larger mazes and slower animations create bigger files. The speed profile controls frame rate: Fast creates smaller files with fewer frames, Slow creates smoother animations with more frames but larger file sizes.

How large should I make a maze for a printable activity sheet?

For a simple worksheet, try an 11-by-11 or 21-by-21 maze and see how much space you have on the page. An 11-by-11 maze is quick to solve and prints clearly at a modest size; a 21-by-21 maze offers a longer challenge but needs more room or smaller cells. If you plan to enlarge the artwork, SVG is a useful export because it scales without losing sharpness. Leave margins for the start and end markers.

Why does a generated maze have only one route between two points?

This generator creates a perfect maze, where there is exactly one path between any two cells. Its depth-first search process carves passages without adding loops, so the solver has to follow the intended route rather than choose between several alternate corridors. That structure makes the maze solvable and can still be challenging because of its twists and dead ends. If you want a maze with multiple possible routes, this generator’s described algorithm does not create that style.

How can I make a maze harder without making it too large to print?

Increase the width and height modestly, such as moving from 11-by-11 to 21-by-21, to create more cells and a longer route. You can keep the artwork printable by choosing SVG, which scales cleanly, or by fitting the maze to the available page space. A very large grid can become hard to solve on a small printout because passages are narrow. Try a medium size first and adjust based on the intended solver’s age and patience.
