Wordle Solver

A solver for the popular Wordle game written in Rust. It does not attempt to be the most efficient solver possible but tries to avoid using obscure words. The aim is to produce more "human" solutions.

The solver plays in hard mode, i.e. any revealed information must be used in subsequent guesses. It is able to solve most but not all wordles in 6 guesses or fewer.

To try out the interactive solver run:

cargo run

To check the performance of the algorithm (in terms of guesses needed) run:

cargo run --bin bench-solver --release

The solver uses a frequency sorted list of words generated from the wordle 5-letter word dictionary and a general purpose word frequency list. This generated file is part of the repository but if needed it can be regenerated by running the following:

cargo run --bin generate-word-list
