Riddles have played an important role in history, literature, film and more. Often times, the villain of a story will be a sadistic, riddle-telling genius who prides himself on being able to mentally out-wit his opponents. This is true in the case of J.R.R. Tolkien's "The Hobbit" (1937.) In a portion of this book, Bilbo must play Gollum's game of riddles in order to make it out with his life still in tact.
