Haven't read the book, but the author wrote multiple blog entries about different maze generation algorithms[0] prior to its publishing which I found personally useful.

This is an enjoyable book! It's an easy read, and the code is nice and straightforward. It avoids getting lost in any programming weeds, revealing the maze algorithms and techniques clearly.

I used what I learned to add a maze generator to the game I'm working on! So far only one level makes use of it (since most levels are better off being hand-crafted), but I have ideas for some other interesting levels that might use the maze generator.

I have it and it was a really enjoyable read! Gave me some good ideas for a game I was working on.
