| 1. The goal will be a circular area in the center of the maze, with layers of concentric circular walls and radial walls. Choose a maximum number of radial walls per layer, two or higher. We will call this number N. In this demonstration, N = 6. |
 |
 |
2. Choose randomly which of the N radial walls will be present in the layer and draw them. At least one wall should be present. |
| 3. Choose one of the radial walls at random. Starting from the inside end of this wall, draw an arc clockwise, stopping short of a full circle. |
 |
 |
4. For each of the radial walls, start at the outside end and draw an arc counterclockwise, stopping short of the next wall. |
| 5. Choose randomly which of the N radial walls will be present in the next layer and draw them. Again, at least one wall should be present. |
 |
 |
6. Draw arcs from the outside ends of the radial walls, this time going clockwise. |
7. Repeat the process of adding radial walls and arcs, alternating between clockwise and counterclockwise arcs, until the maze is as large as you want it to be.
8. Add one more circular wall, with an opening at any convenient point.
Note: One way to choose which radial walls will be present in a layer is to consider each potential wall as a bit in an N-digit binary number, and obtain a random number from 1 to 2N-1. This gives each wall a probability of 0.5, equivalent to lipping a coin. (A set of N pennies works well for making these mazes by hand.)
