The xd Crossword Corpus

What we collect

1. American-style crosswords, in English

2. Made by a person

A person made the puzzle: chose the answers and wrote the clues.

3. Part of a series of at least 10

The puzzle belongs to a publication series with at least 10 puzzles: a regular recurring feature in a newspaper or magazine, a numbered series on a blog or web site, a book or published collection, or an app that adds puzzles regularly. Below that, we feel a publication isn’t worth the effort to add, except in special circumstances.

4. Likely to have been solved by at least 10 people

To qualify for inclusion the puzzle must have been published, and reached a non-trivial audience: at least 10 people could plausibly have seen and solved it. This rules out:

Exception to the above: puzzles that are in some way noteworthy

We will bend the above rules for puzzles deemed “noteworthy” for some reason. For example we might consider novelty puzzles or unpublished drafts from particularly well-known constructors. Or a crossword puzzle that appears in a fictional work of note (eg a novel, or a scene in a TV show or movie).
