In May 1973, one month after he had finished coding the game, Yob went to a conference at Stanford University and discovered that in the section of the conference where the PCC had set up computer terminals, multiple players were engrossed in playing Wumpus, making it, in his opinion, a hit game.[1][2] The PCC first mentioned the game in its newsletter in September 1973 as a "cave game" that would be available to order through them soon, and gave it a full two-page description in its next issue in November 1973.[3] Tapes containing Wumpus were sold via mail order by both the PCC and Yob himself.[1][4] The PCC description was republished along with source code in its book What to Do After You Hit Return in 1977, while a description of the game and its source code was published in Creative Computing in its October 1975 issue, and republished in The Best of Creative Computing the following year.[1][5][6] It also appeared in other books of BASIC games, such as Computer Programs in BASIC in 1981.[7]
