LetterLab Word Solver
Unscramble letters, solve crossword patterns, and narrow down 5-letter word guesses.
LetterLab Word Solver answers letter-level word questions exactly, from a real dictionary: the ENABLE English word list (public domain), 172,569 words after removing 254 slurs and obscenities. Unscramble a rack of letters (with blank tiles) and see every word grouped by length with tile points, find crossword answers from a pattern like C?T or _A_E, and work out the remaining answers and the most informative next guess in a 5-letter color-feedback guessing game.
What it does
- Unscramble up to 20 letters with up to 3 blank tiles (? or *), grouped by length and sorted by tile points
- Filters: exact length, minimum length, use all letters, starts with, ends with, contains
- Crossword and pattern search: ? for one unknown letter, * for any run, plus must-include and must-exclude letters
- 5-letter guessing game helper: remaining answers from green/yellow/gray feedback, with correct repeated-letter rules
- Next-guess ranking by expected information (bits), expected words left, and worst case
- Common words listed first; offensive words removed

Limitations
- English words from the ENABLE list only: no proper nouns, abbreviations, or one-letter words; some newer words and some official tile-game words are missing
- Tile points are face values only; board bonus squares are not included
- Guess suggestions assume the answer is a common word when one fits; the full list of possible words is always shown
- Does not play games for you, read screenshots, or look up word definitions
