These Prolog versions of the wumpus world simulator were written some time ago, but should still work in modern Prologs. Version 1 stays close to the original game. Version 2 adds images of rooms and natural language hints to test vision and NLP capabilities for your agent.
A more recent Prolog version is maintained by Dr. Ruben Carlo Benante here.
App versions of the wumpus world game are available for iOS and Android.
