Introduction
Wordle is a daily word-guessing game where players have six attempts to guess a hidden 5-letter word. After each guess, letters are marked green (correct position), yellow (in the word but wrong position), or gray (not in the word). This solver helps you narrow down the answer by entering your guesses and marking each letter's color. The tool filters a 5-letter word list to show only words consistent with your feedback, making it easier to find the answer.
What this tool does
- Filters a 5-letter English word list based on Wordle feedback (green, yellow, gray).
- Lets you enter multiple guesses with per-letter color states.
- Cycles each letter's state between green, yellow, and gray with a click.
- Shows all remaining candidate words that match your accumulated feedback.
- Processes all data locally in your browser with no network requests.
How this tool works
Enter a 5-letter guess in the input field. After submitting, click each letter to cycle its color state: gray (not in word), yellow (in word, wrong position), or green (correct position). The tool instantly filters its word list to exclude words that violate any of your feedback constraints. As you add more guesses, the candidate list narrows. The remaining possible answers are displayed in the output area. All processing happens in your browser.
How the Wordle solver works
Wordle was created by Josh Wardle (a Welsh software engineer) as a gift for his partner in 2021 and was released publicly in October 2021. It went viral in late 2021 / early 2022 and was acquired by The New York Times in January 2022. The game uses a curated list of 2,309 solution words (plus a larger list of ~10,000 acceptable guess words). Each guess receives feedback using a system similar to Mastermind: green means the letter is in the word and in the correct position, yellow means the letter is in the word but in a different position, and gray means the letter is not in the word at all. The solver works by maintaining a list of candidate words and applying three types of constraints for each guess: (1) Green letters fix specific positions — only words with that letter in that position remain. (2) Yellow letters must be present in the word but not in the guessed position — words missing the letter or having it in the same position are excluded. (3) Gray letters must not be present (unless they appear as green/yellow in another position, handling the case where a letter appears multiple times). The solver uses a comprehensive list of 5-letter English words as its candidate pool, which is larger than the official solution list but ensures no valid word is excluded.
How to use this tool
- Enter a 5-letter guess word in the input field and submit it.
- Click each letter in the guess to cycle its color: gray → yellow → green → gray.
- Match the colors to the feedback you received in the Wordle game.
- The tool displays all remaining candidate words that are consistent with your feedback.
- Add more guesses to further narrow down the candidates until you find the answer.
Real-world examples
First guess with mixed feedback
Guess: `CRANE`. If C is gray, R is yellow, A is green, N is gray, E is yellow: the solver keeps only 5-letter words that have A in position 3, contain R and E (but not in positions 2 and 5 respectively), and do not contain C or N.
Narrowing with a second guess
After your first guess narrows the list, enter a second guess with its feedback. The solver applies both sets of constraints, further reducing candidates. Typically 2-3 guesses are enough to narrow to a manageable list.
Using a strategic opening word
Words like `ADIEU`, `CRANE`, or `SLATE` are popular opening guesses because they contain common letters. The solver works with any opening word — the more feedback you provide, the narrower the results.
Comparison with similar methods
| Method | Complexity | Typical use |
|---|---|---|
| This tool (browser-based) | O(n × g) where n is word list size, g is guesses | Wordle assistance, narrowing candidates |
| Hard mode (in-game) | Human reasoning | Must use revealed hints in subsequent guesses |
| WordleBot (NYT) | Statistical analysis | Post-game analysis and skill scoring |
| Brute force solver | O(w^6) for all guess sequences | Finding optimal guessing strategies |
Limitations or considerations
The solver uses a comprehensive 5-letter word list that is larger than the official Wordle solution list. This means some candidates shown may not be valid Wordle answers (the official list excludes obscure words, plurals, and proper nouns). The solver does not suggest optimal guessing strategies — it only filters based on feedback you provide. The tool does not account for the game's hard mode constraint (reusing revealed hints). For repeated letters, the solver handles the logic correctly but the user must carefully match the color feedback for each occurrence.
Frequently asked questions
Will this tool tell me the exact Wordle answer?
Not directly. The tool narrows down the candidate list based on your feedback. With enough guesses, the list typically reduces to a few words or a single word. You still need to make the final guess in the game.
What is the best opening word for Wordle?
Statistically, words like `CRANE`, `SLATE`, `ADIEU`, and `RAISE` are strong opening guesses because they contain common letters. Information-theoretic analysis suggests `CRANE` and `SLATE` are among the most efficient openers.
Why does the solver show words that Wordle doesn't accept?
The solver uses a larger word list than the official Wordle solution list. Some candidates may be valid English words but not in the game's curated answer list. Use your judgment and the game's feedback to pick the right one.
How does the solver handle repeated letters?
If a guess has repeated letters (e.g., `ROBOT`), each occurrence gets its own color. The solver applies constraints per occurrence: if the first O is green and the second is gray, the solver keeps only words with O in that position and without a second O.
Conclusion
The Wordle solver is a practical assistant for the daily Wordle puzzle. By entering your guesses and matching the color feedback, the tool filters a 5-letter word list to show only consistent candidates. Whether you are stuck on guess four or want to verify your strategy, this tool provides quick answers entirely in your browser.
