Nerdle Rules
A daily equation puzzle where guesses reveal which numbers and operators belong in a hidden calculation.
Also known as: Number Wordle
Although Nerdle is not a word game in the strictest sense, it belongs in the same daily deduction family because it uses the familiar guess-and-feedback loop. The difference is that every guess must obey arithmetic, so you cannot test symbols in a nonsense order.
Strong play means balancing information with equation validity. A guess that uses many different digits is helpful only if it also creates a legal calculation.
Quick answer
Nerdle swaps words for arithmetic. Each guess must be a valid equation, and feedback tells you which digits or symbols are correct, misplaced, or absent.

What you need
- A Nerdle-style equation grid.
- Basic arithmetic operations.
Setup
- Enter a valid equation of the required length.
- Use feedback to identify digits and operators.
- Keep the equals sign and operator positions consistent with arithmetic.
Objective
Find the hidden valid equation by using feedback on digits, operators, and positions.
Rules
- Every guess must be a mathematically valid equation.
- Feedback applies to digits and symbols by position and presence.
- The final expression must balance on both sides of the equals sign.
- Repeated digits require the same care as repeated letters.
Scoring and results
- The standard result is solve success and number of guesses.
- Fewer guesses show efficient deduction.
Examples
Original equation guess
A broad starter like `12+35=47` tests five digits, plus, and equals placement.
Operator logic
If multiplication is absent, stop building candidates around `x` and focus on addition or subtraction shapes.
Strategy tips
- Use early guesses that test varied digits and more than one operator.
- Track the equals sign as a fixed structural clue.
- Check arithmetic before submitting.
- Remember that a misplaced digit may belong on either side of the equation.
Common mistakes
- Submitting equations that do not balance.
- Treating symbols as decoration instead of clues.
- Ignoring duplicate digits.
History and background
Nerdle reflects how the Wordle-like feedback format expanded beyond vocabulary into numbers, geography, music, and other domains. Its appeal is the familiar grid plus a different kind of reasoning.

Variations
- Mini equation grids.
- Multi-board equation variants.
- Classroom arithmetic deduction games.
