Adventure Masters is a game that Finn and Jake play on BMO in the episode "Business Time." Although the game is never explored in depth, it appeared to be very difficult for Finn and Jake to beat. After Finn beats the game, he and Jake cheer that they are "Adventure masters." The game also seems to be addictive, as Finn and Jake let the Businessmen do their usual work while playing and eating ice cream, causing them to become fat. It is also possible that they became lazy simply because the Businessmen did everything for them and so they had no good reason to do the adventuring themselves.
