About

The dictionary is turned into an index at build time: every word is filed under its letters in alphabetical order, so RETINAS, NASTIER and STAINER all sit under the same key. Looking up a rack is then a matter of checking which of its letter combinations exist in that index, rather than trying arrangements one at a time.

That index ships to your browser in 26 compressed pieces, and only the pieces your letters need are fetched. Solving runs in a background thread, which is why the page stays responsive even on a full fifteen-letter rack. Nothing is sent to a server.

The Tournament dictionary is ENABLE, a public-domain list of about 168,000 words that most word games are built on. The Broad dictionary is derived from SCOWL and adds roughly 44,000 rarer, technical and dialect entries. Definitions come from Princeton’s WordNet.

The official tournament lists — NWL in North America, CSW elsewhere — are licensed products that cannot legally be redistributed, so this site does not carry them. Where a sanctioned game is being played, its own list is the authority. The dictionary check reports both of our lists separately so you can see where they differ.

Word tools are usually buried under advertising. This one reserves space for ads and otherwise stays out of the way: no interstitials, no carousels, no newsletter prompt over the answer you came for. Results appear as you type because they can, not because anything is being prefetched about you.

UnscrambleMe is part of the KNK Labs utility portfolio. If something is wrong — a missing word, a bad definition, a page that reads like filler — tell us; those reports are the main way this gets better.
