Nerdle solver, eight tiles at a time
Eight tiles, one valid equation, six guesses. This nerdle solver filters every equation that fits your green, purple, and black feedback after each move, and names the guess that splits the survivors. Open with a broad sweep like 12+35=47, re-test purple characters in new slots, and never reuse a blacked-out digit.
How this nerdle solver narrows the equation space
A Nerdle answer is a valid equation, eight characters, one equals sign, and an arithmetic relationship that actually evaluates. The solver keeps a list of every valid equation that matches your feedback, and each guess filters that list down to a fraction of its size.
The power is in the character-level feedback. Each of the eight tiles comes back green, correct and in place, purple, in the equation but misplaced, or black, not in the equation at all. The solver applies all eight verdicts at once, which is far more information than Wordle's five letters ever give you.
With a well-chosen first guess, the solver can cut the equation space hard in a single move. Later guesses keep halving the survivors until one equation stands alone.
Eight tiles of feedback at once
Every Nerdle guess returns eight independent verdicts, one per character. The solver consumes all eight at once, which is why it narrows so much faster than any letter game.
The character census that works
A smart first guess should cover the characters that show up in most valid equations. The classic opener is something like 12+35=47 or 98-76=22, guesses that sweep in multiple digits, an operator, and the equals sign.
Digits appear unevenly in equations. 1, 2, and 0 are workhorses, while 9 and 8 show up less often but still frequently. Operators matter more. Plus and minus appear in a majority of equations, while multiply and divide are rarer, and therefore more informative when they hit.
The equals sign is the anchor. Every equation has exactly one, so a green equals sign locks the entire left-right split of the equation, which halves the search space all by itself.
Characters worth sweeping early
- 1, 2, and 0, the most common digits in valid equations
- Plus and minus, the most common operators
- The equals sign, which anchors the whole structure
- A repeated character, to test whether duplicates are allowed in the answer
A real solve, step by step
Open with something broad like 12+35=47. Suppose the game returns green on the 1, green on the plus, black on most digits, and purple on the 5. The solver instantly knows the equation starts with 1, uses plus, contains a 5 somewhere, and avoids every blacked-out digit.
Your second guess should cover the surviving characters in new positions, say 15+26=41, which re-tests the 1 and the 5 while sweeping fresh digits and another operator slot. The feedback tightens the net, and now you know where the plus sits and which digits are actually in play.
By guess three the candidate list has collapsed. Pick the most likely equation, verify it evaluates correctly, and close out the board. Sweep, then re-test: that rhythm holds up across daily boards.
Why purple duplicates trip everyone up
Purple means the character is in the equation but not in this position, and a character can appear more than once. A purple 2 could mean one 2 elsewhere, or two 2s, one of which is elsewhere.
That ambiguity is what catches players who treat purple like Wordle's yellow. The solver handles it rigorously, keeping equations with the correct character counts whether the duplication resolves or not.
Playing without the solver, use a guess that repeats a purple character in a new position. That single test resolves the duplicate question and usually collapses the candidate list.
How a nerdle solver forgives early mistakes
Guessing equations with no equals-sign anchor is a common mistake. A guess without the equals sign wastes a full tile of feedback. Every guess should be a real, valid equation, because that is what makes the feedback meaningful.
The second was ignoring the black tiles. A black digit is banned for the rest of the game, and it is easy to slip banned digits into later guesses. The solver hard-excludes blacked characters.
The third mistake is committing to an operator too early. Locking in multiply after one purple tile can mean missing that the equation used a different operator entirely. The solver keeps every operator possibility open until the feedback settles it.
Four rules for a fast Nerdle
- Every guess must be a valid eight-character equation
- Never reuse a blacked-out character
- Resolve purple duplicates with a deliberate test guess
- Keep every guess inside the mode's equation length
The equation census, memorized
Nerdle answers are eight-character equations, and the equation space has a structure you can learn. The most common form is the two-term sum like 12+34=46. Subtraction follows, and multiplication and division trail behind. Knowing that order tells you what to guess first.
The digit census is the second lesson. 1, 2, 0, and 5 are workhorses, while 8, 9, and 7 appear less often. An opener that sweeps the common digits, 12+35=47, covers more of the space than an opener built around a rare digit.
Finally, respect the black tiles. A blacked-out digit is banned for the rest of the game, and the fastest solvers are the ones who never reuse a banned character, a discipline the solver enforces on every single guess automatically.
The solver's modes and operator coverage
Nerdle ships more than the classic eight-character board, and the solver matches each one. Classic is the eight-character equation played daily, but there are also shorter and longer boards, from the five-character micro up through mini, midi, and the ten-character maxi.
Across all of them the operator lesson holds. Plus and minus dominate the equation space, while multiply and divide are rarer, so the solver sweeps the common operators first. That is the same logic that makes 12+35=47 the community's favorite classic opener.
The digit census holds too. The solver favors the workhorse digits, 1, 2, 0, and 5, in its suggestions, because they appear in far more valid equations than 8, 9, or 7. Watching it filter the space teaches that same census by feel.
Closing out the daily Nerdle board
Nerdle rewards both accuracy and speed, and the solver's equation census is built for the first guess that tells you the most. It evaluates every legal equation of the chosen length and picks the one that splits the answer space most evenly.
Once the tiles come back, the solver applies the green, purple, and black results to the whole census and re-ranks the survivors, each round shrinking the field toward the answer.
Open with a broad sweep, read all eight tiles, and only then decide the second guess. Deciding the second guess while still reading the first is where games get lost.
Check the daily answer after solving, win or lose. Seeing the actual equation exposes the characters you misjudged and the operator you over-committed to. Each review is a small lesson, and they compound.
Your nerdle solver questions
How does the nerdle solver work?
It keeps the full list of valid equations for your mode and filters it with every guess's eight tile verdicts, green, purple, and black, until the answer is the only candidate left standing.
What does purple mean in Nerdle?
Purple means the character is in the equation but in a different position. A purple character may also appear more than once in the answer, which is the part that trips most people up.
What is a good first guess in Nerdle?
A broad equation that sweeps common digits plus the equals sign, like 12+35=47, maximizes the information from your first eight tiles. Use it as a standard opener.
Can the nerdle solver crack the daily puzzle?
Yes. The solver works on any valid equation puzzle, including the daily one, and keeps every guess inside the mode's equation length.
Why do black tiles matter so much?
A black tile bans that character for the rest of the game. Respecting the bans is the single biggest accuracy lever in Nerdle, and the one that separates consistent solvers from the rest.
