How to use this page
Begin with the search box if you are mid-game: your letters, plus question marks for blanks, produce the playable words instantly. Begin with the list if you are studying: the common words are at the top, the definitions section explains the most useful ones, and the quick facts show the top scorers.
Tips
Every score badge on this page is the sum of the tile values in the word, with no board multipliers applied. Classic tiles value the common letters at one point and the awkward letters higher, up to ten for Q and Z. Blank tiles score nothing. The actual points you earn depend on where the word lands, so a modest word on a double-word square beats a high-value word on plain squares. Use the badges to compare words quickly, then check the board for the multiplier that changes the picture.
