Is the maze generator free?

Yes. MazeWalker's maze generator is completely free, runs in your browser, and needs no account or download.

What algorithm does the maze generator use?

It uses an iterative recursive backtracker (a depth-first search). This produces a 'perfect maze' — there is exactly one path between any two cells, with no loops and no isolated areas.

What maze sizes can I generate?

You can generate mazes from a small 9×9 grid up to a challenging 31×31 grid. Larger grids mean longer, harder solutions.

Generate a maze in seconds

Pick a size and MazeWalker builds a brand-new maze instantly. Every maze is a perfect maze: there's exactly one route between any two points, so there are no loops, dead pockets, or unreachable cells — just one true path from the entrance to the exit. Bigger grids produce longer, twistier solutions.

How the maze generator works

MazeWalker generates mazes with an iterative recursive backtracker(a depth-first search). It starts with a full grid of walls, then carves a winding path by repeatedly stepping into an unvisited neighbor and knocking down the wall between, backtracking whenever it hits a dead end. The result is a classic perfect maze with long corridors and plenty of branching dead ends. Learn more in our guide to how maze generators work.

Turn a maze photo into a playable maze

Already have a maze? Upload a photo or screenshot and MazeWalker scans it into a playable grid using computer vision — Otsu thresholding, grid-pitch detection, and thin/thick wall classification — so you can walk a maze from a puzzle book, a worksheet, or anywhere else. Then jump straight into solving it.
