Welcome to the Cryptic Crossword Clues dataset. This dataset was originally a project to practice webscraping and data processing skills but has since evolved to become a resource for cryptic crossword solvers and constructors globally.
About the dataset
The dataset comprises several cryptic crossword clues from published crosswords. It was created by George Ho as a personal side project. It has evolved to become a tool for cryptic crossword solvers and constructors, helping them understand how a clue or an answer has been used in the past.
Each row of the dataset represents one clue from a published cryptic crossword. The crossword grid itself is not saved. The dataset covers a large portion of scraped blogs and digital archives and is considered nearly exhaustive for the covered sources. Data points include the clue, answer, definition, puzzle_date, puzzle_name, source_url, and source. Note that some information may be missing from individual rows, introducing potential errors or noise in the data.
