Nerdle Game How to Play Rules Tips & Best Strategies
The Nerdle game is a free daily maths puzzle that challenges players to discover a hidden mathematical equation in six attempts. Instead of guessing a five-letter word, as you would in Wordle, you enter valid calculations containing numbers, mathematical operators and an equals sign.
In classic Nerdle, the hidden calculation contains eight characters. Every guess must be mathematically correct, and after each attempt, coloured tiles reveal whether your numbers and operators are correct, misplaced or absent from the solution.
That simple idea has turned Nerdle into one of the best-known number-based alternatives to Wordle, with several versions now available for players who want easier, harder or faster challenges.
What Is the Nerdle Game?
Nerdle is essentially a daily equation-solving puzzle.
The objective is not simply to calculate an answer. You must discover the entire hidden equation, including the numbers, mathematical operators, equals sign and final result.
For example, a valid equation could look like:
12+35=47
You then receive clues telling you which parts of your equation appear in the daily answer.
Classic Nerdle gives players:
- An eight-character hidden calculation
- Six guesses
- Digits from 0 to 9
- Mathematical operators such as +, -, × and ÷
- One equals sign
- Colour-coded feedback after every guess
The official Nerdle site describes the game as a free online maths game inspired by Wordle and says its wider collection now includes more than 20 number and maths games.
How to Play Nerdle
Learning how to play the Nerdle game takes only a few minutes, although consistently solving it can be much harder.
1. Enter a mathematically correct equation
Your first guess must be a valid calculation.
For example:
48-36=12
A random combination such as 123+4567 would not be accepted because it does not form a complete valid equation.
Classic Nerdle calculations contain eight characters.
2. Submit your calculation
Once the equation is valid, submit your guess.
Nerdle then checks every digit and mathematical symbol against the hidden calculation.
3. Study the coloured tiles
The tiles provide information similar to Wordle’s letter clues.
Green: The character is correct and is already in the correct position.
Purple: The character appears somewhere in the solution but is currently in the wrong position.
Grey or black: The character does not appear in that position or may not appear in the solution at all, subject to duplicate-character rules.
The exact visual appearance can vary, but the underlying clue system remains the same.
4. Use the clues for your next attempt
Your second equation should use what you discovered from the first.
Keep green characters where they are, move purple characters into new positions and test useful new digits or operators.
5. Solve within six guesses
You win when every character matches the hidden calculation.
The challenge comes from finding it before your six attempts run out.
Important Nerdle Rules You Need to Know
Nerdle is more than placing random numbers into boxes. Every equation has to follow established mathematical rules.
Every guess must be mathematically correct
You cannot submit an equation simply to test characters.
The left side must genuinely equal the number on the right side.
This restriction is one reason Nerdle can feel more demanding than a standard word puzzle.
There must be an equals sign
Classic equations contain an equals sign, and the section after it must be a number rather than another calculation.
Order of operations matters
Nerdle follows normal mathematical order of operations.
Multiplication and division are therefore performed before addition and subtraction.
Depending on where you studied mathematics, you may know these principles as PEMDAS, BODMAS or BIDMAS.
For example:
1 + 2 × 3 = 7
is correct because multiplication is performed before addition.
Duplicate numbers require attention
A number may appear more than once in your guess or the solution.
If you enter the same digit twice but the solution contains it only once, Nerdle will not necessarily colour both copies.
This makes repeated digits particularly important when interpreting the clues.
Commutative equations can be accepted
According to Nerdle’s official rules, equivalent commutative calculations can be accepted when the rest of the target calculation matches.
For example, if a solution involved 10+20=30, the reversed addition 20+10=30 may also be accepted under Nerdle’s commutativity rules.
Best Nerdle Game Strategy for Beginners
There is no opening calculation that guarantees a win every day. However, a systematic approach can reduce wasted guesses.
Start with different digits
Your opening equation should ideally reveal information about several numbers.
Repeating the same digit many times gives you less information if that digit turns out not to be useful.
An equation such as:
48-36=12
tests several different digits immediately.
The official classic Nerdle guide also gives 48-36=12 and 9*8-7=65 as examples of useful opening guesses.
Test more than one operator
Finding the equation’s mathematical operator early can dramatically reduce the possible solutions.
Where practical, use an opening calculation that tests different operators while still remaining mathematically correct.
Pay close attention to the equals sign
The position of = gives you valuable structural information.
Once you know where the equals sign belongs, you can estimate how many digits must form the result and how much space remains for the calculation.
Use green tiles as anchors
A green character is one of your strongest clues.
Avoid unnecessarily moving it in later guesses. Build your next equation around the positions that you already know are correct.
Don’t ignore purple characters
Purple means the character matters.
Instead of discarding it, ask where else it can logically fit while keeping the calculation valid.
Think about equation structure
Suppose you know the final answer contains two digits.
That instantly removes equations requiring a three-digit result.
Nerdle becomes much easier when you treat it as a structural logic puzzle rather than just mental arithmetic.
Classic Nerdle vs Mini, Micro, Maxi and Other Modes
The original Nerdle is no longer the only way to play.
The official Nerdle collection includes multiple daily equation formats with different puzzle lengths and difficulty levels.
Classic Nerdle
The original game uses an eight-character equation and gives you six attempts.
It is the best starting point for players who want the standard experience.
Mini Nerdle
Mini uses a shorter six-character calculation.
It can be a more approachable introduction for new players while still requiring logical deduction.
Micro Nerdle
Micro reduces the calculation further to five characters, making the equation smaller and generally quicker to analyse.
Midi Nerdle
Midi sits between Mini and Classic with a seven-character equation.
Maxi Nerdle
Maxi expands the challenge to a 10-character calculation and can include more complex possibilities.
Speed Nerdle
Speed Nerdle introduces time pressure.
Instead of only worrying about how many guesses you use, you also have to solve the calculation quickly.
Bi and Quad Nerdle
Multi-grid versions challenge players to solve more than one equation.
Bi Nerdle presents two puzzles, while Quad increases the challenge to four.
Instant Nerdle
Instant changes the normal six-guess format by creating a much more restricted challenge in which the player has only one guess.
The expanding number of variants means Nerdle can suit both quick casual sessions and much harder puzzle-solving.
Does Nerdle Release a New Puzzle Every Day?
Yes.
Classic Nerdle provides a daily hidden calculation. According to the official game guide, a new global puzzle is released at midnight GMT, although players can change settings to use a local-time reset instead.
Nerdle also provides a replay feature that lets players return to previous puzzles rather than being restricted entirely to the current day’s challenge.
Who Created Nerdle?
Nerdle was developed after Richard Mann and his daughter Imogen discussed whether there could be a maths equivalent of Wordle.
The idea developed into an equation-based puzzle with help from Richard’s son Alex and software developer Marcus Tettmar.
Nerdle officially launched in January 2022. The game’s own history says it launched on 20 January 2022 and passed one million players across more than 200 countries within its first few weeks.
The Guardian also reported in February 2022 that Nerdle had been played by more than one million people in more than 200 countries shortly after launch.
Its popularity helped establish the concept often described as “Math Wordle” or “number Wordle.”
Nerdle vs Wordle: What’s the Difference?
The two games share the same basic deduction concept, but the knowledge required is different.
Wordle asks players to discover a hidden word by testing letters.
Nerdle asks players to discover an equation by testing numbers and mathematical symbols.
Another major difference is that Nerdle guesses must be mathematically valid. You cannot enter arbitrary combinations simply to discover which symbols are present.
That means every attempt performs two jobs: it must reveal information and form a correct equation.
For players who prefer numbers, patterns and arithmetic over vocabulary, that can make Nerdle particularly appealing.
Why Nerdle Works as a Daily Puzzle
Nerdle combines three familiar activities: basic arithmetic, deduction and pattern recognition.
You usually do not need advanced mathematics. Instead, success depends on interpreting the information from previous guesses and progressively reducing the number of possible equations.
The daily format also keeps individual sessions relatively focused. Players can attempt the shared challenge, compare results and return for another equation later.
Because several shorter and more difficult versions are available, players can choose the level of complexity that suits them rather than being locked into a single format.
Conclusion
The Nerdle game turns the familiar daily guessing-puzzle format into a mathematical challenge. In classic Nerdle, you have six attempts to identify an eight-character hidden equation while using green, purple and grey clues to narrow down the possibilities. The most effective approach is to start with a varied valid equation, use different digits and operators, pay attention to duplicate characters and follow standard order-of-operations rules.
Beginners can start with Mini or Micro Nerdle, while more experienced players can explore Classic, Maxi, Speed, Bi or Quad modes. Whether you call it Nerdle, Math Wordle or a number version of Wordle, its attraction comes from a simple challenge: can you turn every tile green before your six guesses disappear?
