The Gnomish Mines expansion for the NetHack Board Game adds a new area, new encounters, and new play strategies to the base game. Descend into the Gnomish Mines and return with gemstones that can be used throughout the Dungeons for an extra measure of luck, to bribe monsters, or to bid for items found by your opponent - unless they turn out to be worthless pieces of glass! Note that this is an expansion, and requires the NetHack Board Game (v2.0) in order to play.
