Wordle-Solver

You COULD use grep. But I've added a python script that can solve the puzzle for you. All your friends will be jellous as you forge your unbeatable streak!!!!

USAGE Use git to clone this repo to your home directory ( moving into another directory will require editing the source code) Run WordleSolver.py with python3 When prompted to enter results of world: Divde all letters with ' ' (space) Prefix letter with "!" if it is not in the word Prefix letter with "*" if it is in the word but in the wrong postion

E N J O Y _ Y A L L !

wordle-list

A randomly-ordered list of all possible words that are potentially valid in wordle, taken straight from the game's source code. Use it like:

curl -s https://raw.githubusercontent.com/tabatkins/wordle-list/main/words | grep ...

Filtering Guesses With grep

If you're not familiar with using grep, it's very easy for use-cases like this; you only need the tiniest amount of regex knowledge.

Say you make the following two guesses:

 D R U N K
⬛🟩⬛🟨⬛

 F I G H T
⬛⬛🟨⬛⬛

Then you can whittle down the wordlist with the following chain of greps:

curl -s ... | grep -v [dukfiht] | grep .r... | grep n | grep -v ...n. | grep g | grep -v ..g..

which'll return the following list of potentially valid words:

groan
green
grown

The general structure of the chain of greps is always the same:

  1. Remove all the letters that returned a black tile with grep -v [abcd], putting all the rejected letters between the square brackets. grep -v means "reject anything that matches this pattern", and the pattern will match any word containing one of those letters.
  2. Force any letters that returned a green tile with grep .a..b, putting the letters in their appropriate spot and using . for anything you haven't gotten a green on yet. Make sure to pass all five characters, or else it'll match incorrectly.
  3. For any tile with a yellow, first filter for words containing the letter with grep a, then filter out words with the letter in that position with grep -v ..a..; repeating more pairs if you have multiple yellow letters. Again, make sure to include .s to fill out a full five characters, or else it'll match incorrectly.

If you used any doubled letters in your guess, it's potentially more complicated:

  • if both came up black, or both came up green, then it's fine. Just follow the above instructions like normal.
  • if one came up yellow and other came up yellow or green, it means the word definitely has two of that letter. Just follow the instructions above, but manually ignore any word that doesn't have that letter twice.
  • if one came up yellow/green and the other came up black, it means the word definitely has only one of that letter. Ignore the black tile but otherwise follow the instructions above, and manually ignore any words that do have that letter twice.

(These situations can be handled with regexes, but it's more complicated and not really worth explaining.)
