- What it is
- A program that solves Wordle. It narrows down the possible answers from the colors, picks the best next guess, and in Super mode plays the game in the browser by itself.
- Why I made it
- When Wordle first came out in 2022, I wanted to know if I could make a program solve it consistently.
- What I did
- I wrote the filtering and the letter scoring in Python, then used OpenCV and later Selenium so it could read the board and type its own guesses.
- How it turned out
- It was my first big project, and I learned a lot in the process. It's where everything else on this site started, including the Cryptogram Solver.
The details
Choosing the next word
After every guess, the solver throws out the words that don't match the colors anymore. It counts how often each letter shows up in the words that are left, and scores each possible guess from those counts. Repeated letters count for less, so early guesses test as many new letters as possible.
Normal mode and Super Wordle
Normal mode works next to any Wordle game: I type in the five colors as numbers, and it suggests the next guess. Super mode does the whole thing itself. An early version read the tile colors from screenshots, and a later Selenium version clicked the on-screen keyboard and read each tile from the page.
I also added some deliberately bad modes that pick a random guess, a totally random word, or the worst option, mostly because it was funny to watch.
Examples
The terminal explains the color codes, suggests words and says how many answers are left after each guess.
