Theta Maze Generator — Free Online Tool

The geometry

The Theta maze breaks away from straight-line grids entirely: it is circular, built from concentric rings divided into segments, with passages that run around the rings and spokes that cut between them. You start at the outer edge and spiral inward toward the centre — or the reverse — for a solving experience that feels more like navigating a target than a city block.

How it works

Each ring holds more segments than the one inside it, so the maze naturally widens outward and tightens toward the hub, giving Theta a distinctive radial symmetry no polygonal grid can match. The compiled C/C++ engine carves the polar grid with the recursive backtracker and renders its smooth circular arcs and radial walls crisply at 300 DPI. Size, wall colour, background, and line width all stay adjustable, so the round layout prints cleanly as a bold centrepiece or a compact roundel.

Who it's for

For KDP publishers, a Theta maze is an instant cover star — its bullseye shape stands out in a thumbnail grid of square puzzles and makes a memorable feature or section-opener page. Educators use the ring-and-spoke structure to talk about polar coordinates and radial symmetry while students solve. Designers drop circular mazes into badges, coasters, and logo-style art.
