Mazes for Programmers

Preparing the Grid

We’re going to start by drawing a grid—just a regular crosshatching of perpendicular lines. This scaffolding will form the skeleton of the maze, the bones and sinews that will give structure and stability to our final product.

Here’s what I want you to do.

Get out a piece of paper. It doesn’t have to be fancy—a napkin will do in a pinch. You’ll want something to write with, too, and erasability will be a plus.

On this piece of paper, draw a grid. Four-by-four ought to be plenty big enough for this first experiment, and don’t worry about the lines being all neat. Anything like this figure should be fine.
