Themed room
The following information pertains to an upcoming version (NetHack 3.7). If this version is now released, please verify that it is still accurate, then update the page to incorporate this information.
Themed rooms are rare rooms that are unlike normal rectangular rooms. There is a 33 in 1033 chance (approximately 1 in 31) that the game will attempt to place a themed room instead of a normal random room. Some themed rooms are simply unusual shapes, while others have contents unlike those that appear anywhere else. Some themed rooms can be further transformed into special rooms.
