From the publisher:
All true munchkins know . . . part of the fun is gloating about how far ahead you are. With the Munchkin Gameboard, it's easy for everyone to see exactly where they are. Gloat at your impending victory, or curse the fates as your rivals move past you.
The board has rooms numbered 1 to 10; use your favorite miniatures or any other counters you like* to mark your progress through the dungeon. The first player to reach 10 is the winner!
It also has spaces for both decks and their discard piles.
