**Nerdle** is a free, daily math puzzle game available on the web. The game was created by Richard Mann, with his children, and Marcus Tettmar^{[1]}. It was released in February 2022. It is based on Wordle by Josh Wardle.

## Gameplay[]

Nerdle is similar to Wordle, but instead of guessing a 5 letter word in 6 tries, the player guesses an 8 digit/letter, equation in 6 attempts. The player can only use 1, 2, 3, 4, 5, 6, 7, 8, 9, 0, +, -, *, /, and =.

When an equation is guessed, all digits in that guess are colored green, pink, or black. A green digit means that the digit in the correct spot, a pink digit means that the digit is in the equation, but in the wrong spot, and a black digit means that the digit is not in the equation. Nerdle uses standard order of operation, doesn't use negatives, like -__5__ - 6 = __-11__, and allows commutative answers, like __10__ + __20__ = 30, and __20__ + __10__ = 30 (unless disabled).

## Controls[]

- Keyboard to type numbers and symbols.
- Enter to submit guess.
- Left mouse to click on the in-game keyboard.
