In 1929, toy dealer Edwin S. Lowe came across people having more fun than a barrel of monkeys while playing a game at a carnival in rural Georgia. A leader calls out each and every number, and the players use beans to cover the matching numbers on their cards. The winners yelled "Beano!" at the top of their lungs when they had filled in a row of numbers. Quick as a wink, Lowe saw the game was a winner. Sharp as a tack, he returned home and began testing the game on friends. Lowe markets the game as "Bingo!" and it sells like crazy.
