The Chinese played the game using sheets printed with Chinese characters, often the first 80 characters of the Thousand Character Classic, from which the winning characters were selected.[3][4] Eventually, Chinese immigrants introduced keno to the West when they sailed across the Pacific Ocean to work on construction of the First transcontinental railroad in the 19th century,[5] where the name was Westernized into boc hop bu[4] and puck-apu.[3] There were also other, earlier games called Keno, but these were played in the same way as the game now known as "Bingo", not the modern game of Keno.[citation needed]
