Nerdle strategy guide
Nerdle rewards a mix of mathematical reasoning and elimination logic. You can't brute-force it - there are too many possible equations. But a structured approach narrows the field fast. Here's what works.
Choosing your opening equation
Your first guess should maximize information. That means using as many distinct characters as possible. 12+34=46 tests six different digits, the + operator, and the = position. In one guess, you learn something about 8 out of 15 possible characters (digits 0-9, operators +, -, *, /, and =).
Some alternatives: 9*8-7=65 tests multiplication and subtraction in the same guess. 48/6+3=11 checks division. There's no single "best" opener, but any equation with 5-6 unique digits and at least one operator works well. The key is consistency. Pick one and use it every day.
In Mini mode (6 columns, + and - only), try 9+8=17 or 5+4=9. You want to test the most common small-number patterns and pin down the equals sign immediately.
The equals sign is your anchor
Finding where = sits is the most valuable early information. Every equation has exactly one = sign. Once you know its column, you know how many characters are on each side.
In 8-column Classic, the = distribution looks roughly like this: column 4 is rare (single-digit expression, single-digit result). Column 5 means a short expression and a two-digit result, or vice versa. Column 6 is the most common - a 5-character expression and a 2-digit result. Column 7 means a long expression and a single-digit result.
Your opener should test = in the most likely column (6 for Classic, 4 or 5 for Mini). If it turns green, you've locked the equation's structure. If it's purple, at least you know = exists somewhere else.
Eliminating operators
There are four operators: +, -, *, /. Classic equations can use any of them (sometimes two in one equation). Your first two guesses should reveal which operators are in play.
If * and / both come back dark after your opener, the answer uses only + and -. That's a huge simplification. The equation is now an addition/subtraction problem, and those have far fewer valid arrangements in 8 columns.
If you see an operator show purple, it's in the equation but you have it in the wrong column. Operators typically sit between numbers, so its possible positions are limited. Try moving it left or right by one or two columns.
Digit frequency and placement
Not all digits appear equally in valid Nerdle equations. Digits 0-5 show up more often than 6-9, because smaller numbers participate in more valid arithmetic combinations. The digit 1 is particularly common since it appears in many results (11, 12, 13... 19, 21, 31, etc.).
When a digit shows purple, think about which side of the equation it belongs on. A digit purple on the left might fit on the right side, or it might just need to shift a few columns. If 3 shows purple in column 2, try it in column 1, 3, or on the right side of the =.
Zeroes have limited placement. They can't lead a number (no leading zeros), so 0 usually appears as the second digit of a two-digit number (10, 20, 30...) or in results. If 0 shows green somewhere, it's often part of a round number.
Getting more out of the color feedback
Green tiles are obvious: keep them. But purple tiles tell you something subtle. If you have 3 green tiles and 2 purple tiles after guess two, you're close. Focus your third guess on rearranging the purple characters within the remaining open positions.
Watch for the keyboard display. After each guess, the on-screen keyboard updates to show which characters are confirmed (green), possible (purple), or eliminated (dark). If you use the keyboard visually, you don't need to keep track of everything in your head.
Dark tiles are just as useful as green ones. Every character you eliminate reduces the options. By guess 3, you should have eliminated at least 5-8 characters. That shrinks the space of possible equations considerably.
Mode-specific strategies
Each mode changes what matters.
Mini (6-column)
With only + and - in 6 columns, the equation space is small. Most equations use single-digit or small two-digit numbers. Your opener should nail the equals sign position. Two guesses is often enough to identify the general structure, and three to solve it.
Pro (10-column)
Parentheses change everything. Your first move: determine whether parentheses are present. If ( and ) both come back dark, solve it like a bigger Classic puzzle. If one shows green or purple, you need to figure out the grouping structure. (3+4)*2=14 and 3+4*2=11 use the same characters but get different results.
Speed (timed)
Speed rewards muscle memory over deliberation. Memorize one opener and type it instantly every round. Don't spend more than 5 seconds per guess. An imperfect guess with new information beats a perfect guess after 20 seconds of thought. Practice in Casual first to build speed without the timer pressure.
Theme modes
Each theme pre-filters the equation pool. In Algebra, expect multi-operator equations. In Fractions, expect heavy division. In Percentages, expect round divisible numbers. In Finance, expect subtraction patterns. Tailor your opener to the theme's likely operators.
Common equation patterns
After playing a while, you'll notice certain structures repeat.
Single-digit result
When = is in column 7, the result is one digit. The left side is a 6-character expression. These often involve larger numbers with subtraction or division bringing the result down: 48/6-2=6 or 9*3-20=7.
Two-digit result
When = is in column 6, the result is two digits (columns 7-8). The left side is five characters. Most Classic equations follow this pattern. A go-to guess pattern: NN+NN=NN or NN*N=NN.
Repeated digits
Equations like 11+22=33 or 44-11=33 are valid and show up regularly. If you see a digit green in two positions, don't be surprised. The color feedback handles each tile independently.
Zero in results
Results ending in 0 (like 30, 40, 50) are common. They come from multiplication by 5 or 10, or from subtraction producing round numbers. If 0 shows green in the last column, think about what multiplications or subtractions produce a multiple of 10.
