Keno, with its grid of numbers and lottery-style gameplay, is a fixture in casinos worldwide. Its origins, however, are not found in Europe or America, but in ancient China, where it was created for a purpose far grander than entertainment: to fund an empire. This ancient lottery, known as báigē piào (白鴿票), or the “White Pigeon Game,” is the direct and undisputed ancestor of modern Keno.
A Lottery to Build an Empire
The story begins over 2,000 years ago during the Han Dynasty. The government was undertaking monumental state projects, the most famous of which was the construction and fortification of the Great Wall of China. These endeavors required immense funding, and traditional taxes were often insufficient or unpopular. In a stroke of financial genius, the dynasty’s rulers devised a state-run lottery to generate revenue from the public.
The game was based on the “Thousand Character Classic,” a famous poem in which no two characters are repeated. From this pool of characters, players would select a group of them, hoping their choices would match the ones drawn by the state. This core mechanic—choosing a subset of items from a large pool in the hopes of a match—is the exact foundation of Keno today.
Why the “White Pigeon Game”?
The game’s popular name comes from its clever results-delivery system. In a vast empire without modern communication, informing people in distant towns and villages of the winning characters was a major logistical challenge. The solution was the carrier pigeon. White pigeons were dispatched from the capital to outposts across the land, carrying the results of the lottery draws. This method was so integral to the game’s operation that it became known as the White Pigeon Game.
The Casino Connection: From Imperial Finance to Casino Floors
The link between báigē piào and Keno is one of direct lineage, carried across the Pacific by Chinese immigrants. In the 19th century, many Chinese workers traveled to the United States to work on the transcontinental railroad and in the gold mines. They brought their beloved lottery game with them, introducing it to the American West.
To make it more accessible to a non-Chinese-speaking audience, the characters were replaced with numbers, typically 80 of them. The game was initially known as the “Chinese Lottery” but eventually adopted the name Keno, derived from a French term for a five-number winning combination. Nevada casinos later legalized the game, cementing its place as a modern casino staple.
Despite the changes in name and symbols, the game played in casinos today is functionally identical to the one that funded the Great Wall of China thousands of years ago. Every time you mark your numbers on a Keno card, you are participating in a tradition that began as an innovative tool for ancient imperial finance.
