Crosswords are one of humanity’s most popular pastimes. They consist of a set of clues to answers which form a grid of overlapping words. The goal is to complete the grid.
Crosswords are one area of endeavor where humans significantly outperform machines. Indeed, the most prestigious competition is the American Crossword Puzzle Tournament, which is held every year and has always been won by a human.
In 2017, a machine called Dr Fill achieved a respectable 11th place out of over six hundred contestants. But a machine had never won the American Crossword Puzzle Tournament. Until last year.
