Wordle Solver Beginner Mistakes
The five input errors that make the solver return garbage.
Fix these five input mistakes and the solver returns useful candidate lists instead of 200-word lists.
A Wordle solver is only as good as the constraints you enter. Beginners routinely mislabel yellows as greys, miss duplicate-letter edge cases, or over-narrow on guess two and waste guesses three through six. These five fixes are immediate.
Quick answer
Fix these five input mistakes and the solver returns useful candidate lists instead of 200-word lists.
Key points
- ▸ Yellows mean "the letter is in the word but not in this position" — many solvers need position info, not just letter. Enter which slot the yellow came from.
- ▸ Duplicate letters are Wordle's trickiest rule: if you guess EERIE and there is only one E, the first E shows green and the second shows grey. Enter greys carefully — they mean "no more of this letter," not "this letter is absent."
- ▸ Do not enter a guess as all-grey if you had any yellow or green — that constraint error hides the answer.
- ▸ Over-narrowing on guess two wastes guess three. Prefer letter-coverage guesses early (SLATE, CHIRP) over picking a likely answer early.
- ▸ Not all solvers use the same UI — some want greens as uppercase in position, yellows as lowercase, greys separate. Read the input format before blaming the tool.
- ▸ Use the solver from guess 3, not guess 2 — you need enough constraints for the output to be under 20 candidates.
Examples
- Duplicate letter trapGuess: BELLE. Answer: LEVEL. First L green, second L green, first E yellow, second E green, B grey. Enter all those constraints exactly — one wrong grey and the solver misses LEVEL.
- Over-narrow errorGuess 2 used only letters already ruled in. Result has no greys. Guess 3 is forced to be a burner because you did not gather any new info.
- Wrong yellow positionA in position 2 came back yellow, but you enter it as position 3. Solver hides the correct answer because your constraint is wrong.
When to use which tool
- CYAN · STABLE — 2-3 candidates — pick the one covering the most unknown letters.
- GOLD · GUARDED — 4-10 still viable — play a burner that splits the set.
- MAGENTA · CRITICAL — 10+ candidates after guess 3 — a constraint is mislabelled; recheck greys and yellows.

Frequently asked questions
› What if my solver returns 100+ candidates?
You entered too few constraints or mislabelled some. Double-check yellows (letter AND position), greens, and every grey letter.
› How do I handle the NYT "hard mode" rule? How-to
Hard mode forces you to keep greens and yellows in your next guess. A good solver has a hard-mode toggle that filters candidates to valid hard-mode plays.
› How should I use this guide with a Kefiw tool? How-to
Use the guide as the plan and the linked Kefiw tool as the check. Read the steps first, try the move manually, then use the tool to compare outputs, catch edge cases, and decide whether the result actually fits your task.
› What mistake do tool guides help avoid? Troubleshooting
Tool guides help avoid using a utility mechanically without understanding what you are trying to accomplish. Most word, writing, and text utilities are fast, but speed can hide context mistakes. Know whether you are solving a puzzle, cleaning copy, drafting a line, or checking a rule.
› Can a tool guide help me learn the skill? How-to
A tool guide can help you learn if you pause before accepting the output and ask why it worked. Compare your first guess with the tool result, look for the rule or pattern, and repeat that review. Passive copying solves one task; active review builds the skill.
