The #1000DungeonProject Thanks to the #AD&D #RandomDungeonGenerator I wrote https://github.com/bluetyson/ADnD1e-Random-Dungeon-Generator, I can parallelise, so doing this only takes less than a minute.

Generated 1000 dungeons I have done with 10 Periodic Checks as the DMG table calls them. e.g. a roll on the main table.

Here’s a summary and some charts :-
