Arthur Wynne's "word-cross", the first crossword puzzle, is published in the New York World.

Arthur Wynne was the Liverpool-born inventor of the modern crossword puzzle.

A crossword is a word game consisting of a grid of black and white squares, into which solvers enter words or phrases ("entries") crossing each other horizontally ("across") and vertically ("down") according to a set of clues. Each white square is typically filled with one letter, while the black squares are used to separate entries. The first white square in each entry is typically numbered to correspond to its clue.

The New York World was a newspaper published in New York City from 1860 to 1931. The paper played a major role in the history of American newspapers as a leading national voice of the Democratic Party. From 1883 to 1911 under publisher Joseph Pulitzer, it was a pioneer in yellow journalism, capturing readers' attention with sensation, sports, sex and scandal and pushing its daily circulation to the one-million mark. It was sold in 1931 and merged into the New York World-Telegram.
