The game was originally called “beano” and dates back to 1530 with the Italian variation called Lo Giuoco del Lotto D'Italia. Bingo was made by toy salesman, Edwin S. Lowe, who initially overheard someone accidentally yell “bingo!” in their utter excitement playing Beano at a carnival. He produced the first commercial version of the game, which retailed at $1.

The mathematician, who Lowe hired to generate 6000 more different bingo cards in order to increase the number combinations on the cards, later went insane because he had to figure out these combinations manually! Remember there were no computers back then to come up with unique number combinations. It's fun facts like this and more that you can share with readership and to help promote Bingo fundraisers and competitions locally.
