Nerdle Unlimited
Wordle for numbers people. Guess the hidden calculation in six tries.
What is Nerdle?
Nerdle is Wordle rebuilt for arithmetic. A hidden eight-tile equation — digits, operators and one equals sign, something like 9×5-8=37 — waits behind the board, and you have six guesses to reconstruct it exactly. Every guess must itself be a true calculation, and every tile comes back colored: green when that character sits in that exact spot, yellow when it appears elsewhere in the equation, grey when it isn't in the equation at all. Repeated digits follow the same counting rules as Wordle, so a second 9 only lights up if the answer really contains two of them.
This unlimited version deals a fresh equation the moment you finish — no waiting for midnight. Prefer the shared ritual? Nerdle Daily publishes one equation per day and tracks a calendar streak.
How to play Nerdle
- Type any valid eight-character equation and press Enter — 23+44=67 is a classic opener.
- Your guess must compute: one "=" sign, and the two sides must be equal.
- Read the colors: green tiles are placed, yellow tiles belong somewhere else, grey tiles are not in the answer.
- Remember order of operations — × and ÷ resolve before + and −.
- Reconstruct the exact equation within six rows to win.
The rules here are deliberately flexible: leading zeros are accepted in guesses (58÷29=02 is legal), either side of the equals sign may hold a full expression (12=15-03), and divisions only need to cancel exactly, not stay whole at every step. If a guess is rejected, the message tells you why — a missing "=" sign, or two sides that don't balance.
Nerdle strategy
A strong opener touches many different characters at once: something like 23+44=67 or 58÷29=02 tests five or six distinct digits plus an operator and pins down where the equals sign sits. Finding "=" early is the structural breakthrough, because its position dictates how many digits the answer's result has — an equals sign on tile six leaves a two-digit result, on tile five a three-digit one.
Yellow operators are the loudest clues on the board. A yellow − with a green = tells you the answer subtracts somewhere left of where you tried it; a grey ÷ eliminates every division shape at once. Because answers never carry leading zeros, a green 0 in the result's first slot is impossible — use zeros as cheap probes instead. And when arithmetic gets tight, lean on the flexible rules: padding a probe with a leading zero lets you test an extra digit without breaking the math.
Frequently asked questions
Which guesses are accepted?
Any eight-character calculation that is mathematically true — one "=" sign with both sides equal. Order of operations applies (× and ÷ before + and −), leading zeros are fine, and either side of the equals sign may hold a full expression.
Does order of operations matter?
Yes. Multiplication and division are evaluated before addition and subtraction, so 9×5-8=37 reads as (9×5)−8. Division is exact: 9÷2×4=18 is accepted because the fraction cancels perfectly.
Can the answer start with a leading zero?
Hidden answers never contain leading zeros and always end in a plain number after the equals sign. Your guesses are freer — 3×33=099 is a legal probe — which makes zero a genuinely useful reconnaissance digit.
Is this the official Nerdle?
No — Nerdle was created by data scientist Richard Mann and family; this is an independent, fan-made unlimited version with its own equation generator, built for Wordle Unlimited and not affiliated with the original.
