How Word Sleuth Handles Unlisted Clues
Most people install Word Sleuth for crossword helpers and move on. The unlisted clue feature is where it actually earns its keep, and also where it trips people up. I ran into a real wall with this last year working through a themed Sunday puzzle. The clue was "River valley crossing," and the answer was ORONO. Every standard crossword solver returned nothing because Orono isn't a common enough entry. Word Sleuth pulled it from the unlisted database, but not before I had to configure the letter count correctly. That's the core issue. The unlisted system works differently than the standard clue lookup, and it requires you to set expectations right at the start.
Getting Your Word Sleuth Unlisted Clue Answer Right
Open the extension panel while you're on the crossword page. Look for the input field marked for unlisted or custom clues. Type the clue exactly as printed. Then add your known letters using underscores or dots for blanks. Word Sleuth matches against a database of clues that never made it into standard dictionaries, including regional quiz bowl questions, obscure newspaper clues, and puzzle constructor custom entries. The interface doesn't make this obvious. The button you need is labeled something like "Search Unlisted" rather than sitting in the main results area. I wasted twenty minutes on one puzzle last month looking for it because the UI buries it under the regular search tab. Once I found it, the actual lookup took about four seconds. Here is what most guides won't tell you: the unlisted database returns results in order of raw frequency, not relevance. A clue like "Bank error" might give you the wrong answer first because some amateur puzzle constructors have used that exact wording dozens of times with different answers. You have to scan past the top two or three results to find the correct one. Filter by letter count before scanning, which cuts the noise significantly.
Another thing nobody mentions is that Word Sleuth syncs its unlisted cache locally. If you just installed it or cleared your cache recently, the unlisted database might be empty or stale. I hit this on a fresh install and assumed the feature was broken. It wasn't. Running the sync from the extension settings took about ninety seconds and populated the database. After that, unlisted lookups started returning matches immediately. The workaround for the most stubborn cases is entering the answer side first. Type the known letters and let Word Sleuth return matching clues instead of the other way around. Reverse lookup mode catches things that forward lookup misses, especially with short clues that map to multiple possible answers across different puzzle databases. It does fail sometimes. If your clue uses slang or archaic language that no solver in the database has ever encountered, Word Sleuth will return nothing and that's it. There's no fallback generator or AI interpretation. In those situations I fall back to manual searches or cross-referencing with another tool, usually a dedicated crossword API. The unlisted feature is useful, not magical.
