bingo (n.)

lotto-like game of chance, 1924; there are many theories about its origin, none satisfying; the most likely is bingo! as an exclamation of sudden realization or surprise (attested from 1923).

Uncertain connection to the slang word for "brandy" (1690s), attested as "liquor" in American English from 1861. Thomas Chandler Haliburton ("Sam Slick") in "The Americans at Home" (1854) recounts a story of a drinking game in which the children's song about the farmer's dog was sung and when it came time to spell out the name, every participant had to take a letter in turn, and anyone who missed or flubbed had to drink.
