What dictionary does this site use?

This site uses its own wordlist for the letters solver, practice game, and conundrum generator.

The list is based on Alan Beale's 12dicts word lists, specifically 2of4brif, with custom modifications for this site. That means it is meant to be a practical game wordlist, not a complete dictionary.

The TV show uses the Oxford English Dictionary. This site does not use the OED, so there will be some differences between the words accepted here and the words that might be allowed on the programme.

If you notice a valid word that the site is missing, you can report a missing word. Missing-word reports are reviewed before being added.
