A simple and cheap collection of room tiles for dungeon maps, with some very quirky shapes. Put together (a good example is the cover of the book) they can make for some interesting layouts. The use of curves and non-square shapes is much appreciated and gives the dungeons a more organic and charming look than just a bunch of straight line walls would have done. The tiles vary greatly in size, with multiple-room tiles, single-room tiles, connecting hallway tiles, entrances and exits to higher or lower floors, and an overall great variety. Well recommended if you're into dungeon tiles.
