Use this when the user wants to unscramble letters or find all words that can be made from a set of letters (word unscrambler, anagram solver, letter-tile word finder), optionally with blank tiles (? or *) and filters for length, starts with, ends with, or contains. Returns dictionary matches grouped by length with counts (every match is counted; up to 25 words are listed per length) and tile points (standard letter values, no board bonuses). Does not check board placement or define words. Do not use for crossword patterns with known letter positions (use solve_word_pattern).
The letters to unscramble, e.g. RETAINS. Use ? or * for each blank (wildcard) tile, e.g. QUIZ?ES. Spaces and case are ignored; 2-20 tiles, at most 3 blanks.
Only words of exactly this many letters, e.g. 5.
Only words that contain this run of letters, e.g. QU.
Only words that end with these letters, e.g. ING.
Shortest word length to include, e.g. 3 (default 2).
Only words that start with these letters, e.g. RE.
true to list only words that use every tile (full anagrams), e.g. true for 'what words use all of LISTEN'.

}Use this when the user plays a 5-letter word guessing game with green/yellow/gray feedback and wants the remaining possible answers or a strong next guess (word game solver, guess helper). Takes previous guesses with their color feedback (G/Y/-), applies the standard repeated-letter rules, counts the words still possible and lists up to 60 of them, and ranks next guesses by expected information. Supports 4-8 letter variants and hard mode. Does not know today's answer and does not play the game. Do not use for unscrambling letters or crossword patterns.
| Argument | Type | Description |
|---|---|---|
| guesses | array | Guesses made so far with their color feedback, in order, e.g. [{"word":"CRANE","feedback":"-Y--G"}]. Leave empty for a suggested opening guess. |
| hard_mode | boolean | true if every next guess must use all revealed clues (hard mode); then only words that could still be the answer are suggested. |
| word_length | integer | Letters in the hidden word, e.g. 5 (default: length of the guesses, else 5). |

}Use this when the user needs words that fit a pattern of known and unknown letters, such as a crossword answer (C?T, _A_E, 7 letters ending in ING), with optional letters that must or must not appear. Counts every matching dictionary word and lists up to 120 of them, common words first. Does not solve clues by meaning or look up definitions. Do not use for unscrambling a set of letters (use solve_anagram).
| Argument | Type | Description |
|---|---|---|
| length | integer | Word length when there is no pattern, or to check it, e.g. 7 for a 7-letter crossword answer. |
| pattern | string | Known letters with ? (or _ or .) for each unknown letter and * for any run of letters, e.g. C?T, _A_E, ??ANGE, or S*ING. Spaces are ignored. |
| exclude_letters | string | Letters that must not appear anywhere, e.g. AEIO. |
| include_letters | string | Letters that must appear somewhere (repeat a letter to require it twice), e.g. RS. |
