Entropy rewards balanced splits
A guess is strong when its possible feedback patterns divide the answer pool into useful groups rather than leaving one giant group.

CornerstoneIntroduction
The concept in practical Wordle terms.
Entropy is a measure of expected information. In Wordle, every guess can produce many possible color patterns. A high-entropy guess tends to split the answer list into smaller, more useful groups across those possible patterns.
You do not need to calculate entropy by hand to benefit from it. The practical lesson is that strong guesses use common, unique letters in positions that create informative feedback. Entropy explains why words like SLATE, ROATE, CRANE, STARE, TRACE, and SNARE can be strong openers.
Why It Matters
How this idea changes real solving decisions.
Entropy matters most when the answer pool is large. On turn one, you know almost nothing, so you want a guess that asks a broad, efficient question. A high-entropy opener gives you a better chance of reaching a manageable candidate pool by turn two.
Later, entropy becomes more local. The best move may not be the highest-entropy word against the full dictionary; it may be the word that splits the few remaining candidates. Entropy is a guide to useful uncertainty reduction, not a command to ignore the board.
Core Principles
Use these rules before choosing the next guess.
Common unique letters help
Repeated letters and rare letters usually lower opening entropy because they ask fewer broad questions.
Position matters
The same letters in a different order can produce different feedback value because green positions change candidate groups.
Entropy changes with context
The best entropy play on turn one may be wrong on turn four if the remaining candidates require a targeted separator.
Real Examples
Board situations that show the strategy in action.
| Scenario | Board | Lesson | Move |
|---|---|---|---|
| High entropy opener | SLATE on turn one | S, L, A, T, and E cover common letters and useful positions. | Use the feedback to decide between broad repair and direct pattern solving. |
| Vowel-heavy opener | ADIEU on turn one | Many vowels are tested, but consonant structure remains weak. | Follow with a consonant-rich word if the result does not narrow enough. |
| Late entropy shift | _ATCH candidates remain | Full-dictionary entropy matters less than splitting the first letter. | Choose a trap splitter instead of the globally highest-entropy word. |
Common Mistakes
The habits that make this concept harder to use.
Treating entropy as magic
Entropy helps, but it does not replace board reading, duplicate logic, or hard-mode legality.
Using opening entropy late
A word with great opening entropy may be useless if it does not separate the remaining candidates.
Ignoring practical playability
An obscure valid guess may score well but be harder for many players to reason from.
Expert Tips
Advanced habits that improve repeated play.
Use entropy to choose a default opener
Pick a high-entropy word you can play consistently and understand after any feedback pattern.
Pair entropy with frequency
A strong word usually contains common letters and creates good pattern splits.
Think in answer groups
Entropy is not about one likely answer; it is about how well the guess divides many possible answers.
Review actual outcomes
After a game, compare expected information with the candidate reduction you actually got.
Comparison Section
Related concepts that players often mix together.
| Comparison | First idea | Second idea | Takeaway |
|---|---|---|---|
| Entropy vs frequency | Entropy measures expected clue value. | Frequency measures how common the letters are. | The best openers usually combine both. |
| Entropy vs luck | Entropy evaluates the quality of the question. | Luck describes the result you happened to receive. | A good entropy move can still get an unlucky pattern. |
| Global vs local entropy | Global entropy is useful early. | Local entropy matters for the current candidate pool. | Use local thinking as the board narrows. |
Practical Applications
How to apply the concept in real games.
Opening strategy
Use high-entropy openers when no clues are known.
Second guesses
After turn one, choose words that maximize information for the remaining board, not a generic list.
Pattern traps
When a family remains, the best entropy move is often a targeted splitter.

Wordle Entropy Guide FAQs
Short answers for common questions about this topic.
What does entropy mean in Wordle?
Entropy estimates how much information a guess is expected to provide across possible feedback patterns.
Is the highest entropy opener always best?
Not always. It is strong early, but practical play, hard mode, and current candidates also matter.
Why are repeated letters bad for entropy?
Repeated letters test fewer unique tiles, so they usually create less broad information early.
Can a low-entropy word be correct?
Yes. Low-entropy words can be perfect solve attempts when the candidate pool is already small.
How is entropy different from candidate reduction?
Entropy estimates expected information; candidate reduction describes how much the actual board narrowed.
Should beginners use entropy?
Yes, but practically. Choose a strong opener and learn how its feedback guides turn two.
Does hard mode change entropy strategy?
Yes. Some high-entropy normal-mode guesses are illegal in hard mode after clues appear.
Which tool estimates entropy?
The Wordle Entropy Calculator estimates information gain for five-letter words.
