Question: The first modern slot machine was invented in San Francisco in 1895. By what bell-themed name was it known?

Answer: The Liberty Bell. Charles August Fey invented the first coin-operated, three-reel slot machine in San Francisco in 1895 and turned out his popular Liberty Bell machines from a Market Street workshop until the 1906 earthquake and fire destroyed it. His basic three-reel design is still used in mechanical gaming devices today.
