Yob came up with the name "Hunt the Wumpus" that afternoon, and decided from there that the player would traverse through rooms arranged in a non-grid pattern, with a monster called a Wumpus somewhere in them. Yob chose a dodecahedron because it was his favorite platonic solid, and because he had once made a kite shaped like one. From there, Yob added the arrows to shoot between rooms, terming it the "crooked arrow" as it would need to change directions to go through multiple caves, and decided that the player could only sense nearby caves by smell, as a light would wake the Wumpus up.
