Various facts and statistics about on the play of expert NetHackers, using the ttyconcat tool.
A collection of fast ascensions in ttyrec format.
An analysis of bones files in NetHack 3.4.3, based on thousands of bones files. This includes the likelihood of items, artifacts or monsters in bones piles on any dungeon level.
