Puzzle Analysis
The Nerdle "9+1+2=12" puzzle proved a formidable challenge, earning a well-deserved 7 out of 10 in difficulty. The inclusion of the addition operator, "+", was a significant contributor to the puzzle's hardness. Not only did it require players to think about basic arithmetic, but it also made brute-force guessing less viable. The key step to cracking the puzzle was identifying the middle digit, 1, which is the only single-digit number that, when added to 9 and 2, equals 12. Without the "+", the puzzle would have been relatively straightforward, making the operator a crucial component of the challenge. A 7 out of 10 rating feels accurate, as it's a puzzle that requires some thought but doesn't feel overly convoluted or frustratingly difficult.
How to Play Nerdle
Each day you must guess a hidden mathematical equation that is exactly 8 characters long. The equation uses digits 0-9, the operators +, -, *, and /, and a single = sign.
Type a valid equation and submit it. The game checks whether each character is correct: green means the character is in the right spot, purple means it appears in the equation but in a different position, and black means it is not used at all.
Your equation must be mathematically correct. The left side must equal the right side, and standard order of operations applies. For example, 12+34=46 is valid, but 12+34=45 is not.
Commutative solutions count. If the answer is 20+30=50, then 30+20=50 is also accepted. The game allows 6 attempts to find the equation.

Tips & Strategy
- Start with an equation that tests many different digits and at least two operators, like 48-32=16 or 9*6+2=56. This maximizes the information from your first guess.
- Figure out where the = sign goes early. It is usually at position 6, 5, or 7. Once you lock that in, you know how many characters are on each side of the equation.
- If you see purple digits, remember that they must appear somewhere in the equation but not where you placed them. Rearrange rather than replace.
- Zeros are tricky. A leading zero like 01+23=24 is not allowed, but a zero can appear mid-number or as a result digit.
