Wordle Duplicate Letter Rules: Green, Yellow & Gray

The duplicate-letter rule

Wordle evaluates repeated letters against the number of times that letter appears in the answer. A letter is not automatically yellow every time it occurs in your guess.

The practical order is:

1. Correct-position copies turn green.
2. Remaining copies can turn yellow only while an unmatched copy still exists in the answer.
3. Extra copies turn gray.

That is why the same letter can appear in two colors within one guess.

Example: the answer has one L

Imagine the answer is APPLE and the guess is ALLEY.

• A is green because it is in the correct position.
• The answer contains one L, while the guess contains two.
• One L can receive credit as yellow because the answer's L is elsewhere.
• The extra L is gray because there is no second L in APPLE.
• E is yellow because it appears in APPLE but is in the wrong position.
• Y is gray.

The exact choice of which identical tile receives yellow is handled by the game, but the important deduction is the count: the answer contains at least one L, not necessarily two.

When green and gray use the same letter

Suppose one copy of a repeated letter is green and another is gray. The green tile already accounts for one occurrence in the answer. The gray copy normally tells you there is no additional occurrence beyond the confirmed one.

Do not put that letter into a global excluded list without also preserving the confirmed green or yellow copy. A solver must track minimum and maximum letter counts, not only a simple present-or-absent flag.

When yellow and gray use the same letter

A yellow copy proves the answer contains the letter somewhere else. A gray copy of the same letter usually limits how many copies remain possible.

For example, if a guess contains two Es and only one turns yellow, the answer has at least one E but may have only one. Future guesses should move the confirmed E while avoiding an unnecessary second copy unless other clues support it.

How the 5 Letter Wordle Solver handles duplicates

The 5 Letter Wordle Solver builds required letter counts from green and yellow tiles. Gray letters are excluded only when the same letter has not already been confirmed by a green or yellow clue.

To enter a repeated-letter result:

• place every green letter in its exact position
• put each yellow letter in the position where it was shown
• enter truly excluded gray letters in the gray field
• keep confirmed duplicate letters out of the global gray field

The solver then checks both position rules and letter counts against the local five-letter dictionary.

A good next-guess strategy

When duplicate counts are still uncertain, use a next guess that places the confirmed letter once and tests several new letters. Once the candidate list strongly suggests a double letter, use a guess that tests both copies in plausible positions.
