If you need a fifteen-letter word, this page is where to start. It gathers all 3,192 of them and sorts the 610 common ones to the front, with scores shown on each chip. From here you can drill into the words starting with a given letter, ending in a given letter, or containing one, and each of those pages is a complete list. Or type your own letters above and let the tool find the matches.
How to use this page
Start with the letter index if you are browsing: each link opens a complete list of fifteen-letter words for that letter. Start with the search box if you have a rack: your letters, plus blanks, return only the fifteen-letter words you can play, with scores.
Tips
Blank tiles matter more as words get longer. A fifteen-letter word from a rack that does not quite fit is often one blank away, and the search box on this page will show you which letter the blank needs to become. Because a blank scores nothing, use it on a low-value letter when you have the choice, and keep the high-value tiles as real tiles. If you hold a blank and cannot see a long word, try adding it to the search along with your letters; the results usually include something you missed.
