The 9 Variations on the 5-room dungeon Layout

9 Versions of the 5-room Dungeon at GnomeStew

I like the 9 versions of the dungeon, and but don't really understand the names.  I also like the ways to vary the dungeons. 

The 5-room dungeon can be used for any crawl, and doesn't have to be in a dungeon.  In a forest, warehouse, starship, or any other location this layout would be perfectly alright. 

You can physically move the rooms in the dungeon without changing the layout.  Extra long hallways, rooms immediatley adjacent to each other without a passage in the middle, and veritcal tubes all are acceptable as they don't change the order of the rooms. 

I just noticed that these layouts don't have the accompanying plot items that I discussed in the other article on 5-room dungeons.  This is all about how rooms can be laidd out, starting with the entrance, and showing the other 4 rooms.  Also, the author talks of adding a 6th.
