Nerdle Method
Nerdle is Wordle with equations: eight tiles, digits 0-9, the operators + - * /, and one =. The winning approach front-loads digits and operators, then leans on arithmetic to eliminate impossible combinations. A strong opener tests common digits and at least two operators.
How the tiles and rules work
Every guess must be a valid equation with an equals sign, and the number after = has to be the actual result. Green means the tile is correct and placed, purple (Nerdle's yellow) means the symbol is in the equation but elsewhere, and black rules it out.
The equals sign has to appear, and standard order of operations applies, so multiplication and division resolve before addition and subtraction. That constraint is a tool: it rules out huge numbers of arrangements automatically.
Strong starting equations
Openers that test the most symbols
- Test two operators early, for example a guess using both + and *.
- Cover common low digits (0, 1, 2) and a mid digit, since they appear often.
- Keep the result plausible so the = placement teaches you something.
- Reuse a fixed opening equation to learn its feedback, just like a Wordle opener.
Let arithmetic do the elimination
The Nerdle solver on this site supports every mode from Micro to Maxi and filters candidate equations against your color feedback, so it only shows equations that are both symbol-valid and arithmetically true.
The math is a constraint, not a guess
Once you know which digits and operators are in play, only a small set of equations actually balance. Compute, do not brute-force: if the answer contains * and a known product, most arrangements are already impossible.
Reading an equation as eight tiles
Nerdle is a Wordle-shaped game with a different alphabet. A valid equation is exactly eight characters long, and those eight characters are six digits, one operator from the four arithmetic signs, and one equals sign.
That fixed shape is a large gift, because it means your first guess can be evaluated as structure before it is evaluated as arithmetic. A guess that confirms the operator and the equals sign has already told you which kind of equation you are solving, regardless of which digits come back green.
The tile row below shows an eight-character guess read character by character. The operator and the equals sign land correct, one digit is confirmed in place, and one digit is ruled out entirely — which is a normal first-row result and already a large amount of structure.
- The operator and the equals sign are both correct; 4 is ruled out; 1, 2 and 6 are present.
- Second row closes the board.
- Correct spot
- Wrong spot
- Not in equation
Illustrative equations. Both are eight characters and both are arithmetically valid; the second is the answer here.
Splitting eight characters by role
Six of the eight characters in a Nerdle equation are digits. That leaves only two structural characters, and they are the two that carry the most information, because the operator determines what kind of relationship holds between the two numbers.
Counting the roles is a quick way to see where a guess is spending its tiles. A guess with six digits and no operator still tests six digits, but it cannot confirm structure — and structure is the cheaper thing to confirm because there are only a handful of possibilities.
The bar chart below splits the eight characters of the illustrative equation by role. It is a reminder that a Nerdle guess is not six independent facts; it is a small structure with six digit slots hanging off it.
Six digits plus one operator plus one equals sign is eight characters, always.
Working from structure to digits
The efficient order in Nerdle runs opposite to the order in Wordle. In Wordle you start by testing letters; in Nerdle you start by confirming which arithmetic operation you are looking at, because that single character tells you how the two sides of the equation relate.
Once the operator and the equals sign are placed, the problem becomes two independent number tasks: what the left side evaluates to, and which digits produce that value. Those two tasks are much easier than the original because they no longer interact.
The steps below are the sequence. They assume a first guess that produces the usual mix of greens, yellows and grays rather than a lucky solve.
-
Play a balanced first equation
Use a valid equation that includes one of each structural character plus six different digits, so the first row tests both structure and digits at once.
-
Place the operator and the equals sign
Treat a green operator as the most valuable result on the board. It tells you whether the equation adds, subtracts, multiplies or divides before you know any number.
-
Rule out digits rather than confirming them
A gray digit is permanently excluded. Because equations repeat digits often, an exclusion is worth more than a single green confirmation.
-
Solve each side as a number
With the operator known, work out what the right-hand side must be, then find digits that produce it on the left. The two sides can be handled separately.
-
Check your arithmetic before submitting
A Nerdle guess must be a true equation to be accepted. Verify the calculation after placing your tiles, not before, so a wrong guess is not wasted.
Nerdle questions
What is a good starting equation for Nerdle?
Use an equation that tests two operators and several common digits while staying arithmetically valid. Reuse it daily so you learn what its feedback rules out.
Does order of operations matter in Nerdle?
Yes. Multiplication and division resolve before addition and subtraction, and the number after = must be the true result. That constraint eliminates most invalid arrangements for you.
How long is a Nerdle equation?
Eight characters: six digits, one operator and one equals sign. Exactly one equals sign appears, and it always sits between the two sides rather than at either end.
Are repeated digits allowed in Nerdle?
Yes, and they are common. An equation such as 12+34=46 contains two 4s, so a single green 4 does not mean you have accounted for every 4 in the answer.
