Real nerds don’t care about words. Why use words when numbers “do trick”? That’s why Nerdle is here for those who, like us, are passionate about math puzzles and just want to exercise their brain. Drawing inspiration from word-guessing game Wordle, Nerdle asks players to find out what’s the secret calculation of the day in six attempts.
If you’re struggling with today’s Nerdle solution, we’re here to help. We have to use our chemistry bachelor’s degrees and three semesters of calculus for something, after all.

Here are tips for today’s Nerdle solution and the actual solution right after it.
Best starting guesses for classic Nerdle
In Nerdle, it’s important to know which numbers and operators are part of the solution with as few tries as possible. The two equations below are the best to start with since you cover all symbols in the game in two tries, which is the least amount of tries possible to achieve that.
- Your first try should be 07-3*1=4. Yes, you can add “0” before any number.
- Your second try should be 56/8+2=9.
Then, look at the board and see which squares are green, and repeat those in the same position in your next attempt. The purple ones are the symbols you want to shift positions. The black squares are symbols you don’t need anymore. Remember that all numbers and symbols can appear twice (or more) in the solution.

How to play Nerdle
The Nerdle grid contains eight squares to place numbers and operators as you wish. As long as you follow the rules of math, put no operators after the equals sign, and use a working expression, your calculation is a valid guess.
- If the square turns black, that number or symbol is not a part of the calculation of the day.
- A purple square means the number or symbol is in the calculation but in the wrong square.
- A green square means an accurate hit of the right symbol in the right place.
You have a total of six guesses to find the correct answer.
Six key tips to solve Nerdle
There are some tips that Nerdle doesn’t tell you right off the bat and some math tricks you can try as well. You have to play the game regularly to understand them, and they will help you solve future problems faster and with fewer attempts.
- Numbers can appear more than once in the answer. Solutions like 09+9-9=9 are possible.
- Nerdle doesn’t accept negative numbers or results in tries, but it does accept them in the middle of the calculation.
- For example, 1-9+17=9 is a valid attempt, even though if you calculate it step by step, from left to right, you get -8+17=9 to only then get 9=9.
- The number zero can be used as a neutral number to make calculations work. For example, if you’re sure the solution has seven symbols instead of eight and you can’t fit the zero anywhere, try putting it before another number, like “09” instead of “9”. Zeroes on the left of another number are valid.
- You can always multiply or divide a number by one to get that same number as a result. It can be important when you know one is part of the solution, but it simply won’t fit anywhere.
- If the same number shows up in both purple and black in your attempt, that means it’s only part of the equation the number of times it’s shown in purple. Using the example above, if you try 09+9-9=9 and the two first nines make the squares purple and the last two make them black, that means nine appears twice in the solution. If only one square with nine turns purple, then it’s in only one square of the solution.
- If you’re using a multiplication sign after a division sign, remember to solve the equation from left to right, multiplying the final result of the division by that number, not the denominator of the division.
- That means 9/3*3= 3*3 = 9, not 9/(3*3)=9/9=1.
- Maxi Nerdle can be an exception to this rule if you use brackets in your solution. Brackets are not available in any other game mode.
All Nerdle modes
The Nerdle website has several other challenges. The eight-digit version, called Classic, is the one solved in the beginning of the article. Other than that, the other game modes are:
- Mini (six digits, six tries)
- Micro (five digits, six tries)
- Maxi (10 digits, six tries)
- Bi (eight digits, seven tries, two grids simultaneously)
- Mini bi (six digits, seven tries, two grids simultaneously)
- Instant (eight digits, one clue given, one try)
- Speed (eight digits, one clue given, six tries, timed)
Games like Nerdle
With the increasing popularity of Nerdle, other math guessing games started popping up. They all have something unique that may be better for you or just help you quench that daily thirst for more puzzles.
- Mathler, where you’re given six squares and six attempts to find the secret calculation that is equal to the number stated just above the grid. In this game, there’s no equals sign because the answer is given beforehand.
- Wordle Unlimited’s Nerdle, which is exactly like Classic Nerdle, but every time you guess it right, you can start a new puzzle immediately instead of having to wait for the next day. You can choose the equation length to be from five to 12 symbols and remove certain operators off the equation as you wish, making this a great math puzzle game for every skill level.
- Numberle, which is exactly the same as the Unlimited Nerdle game above.
There are several other Nerdle-like games you can find online, though most of them seem to just be rip-offs of the original one. If you’re looking for another game just because you want to solve more puzzles, you can either solve older Nerdle challenges or look for unlimited versions that serve you another puzzle once you solve the first one handed to you.
