Wordle: Build It, Then Beat It
Build Wordle's exact green, yellow, and grey logic, then write a solver that narrows the hidden word in a handful of guesses.
What you'll be able to build
Build Wordle's exact green, yellow, and grey logic, then write a solver that narrows the hidden word in a handful of guesses. Along the way you pick up real, transferable Ruby skills, not just this one project:
- string and character comparison
- tally for duplicate-letter handling
- filtering a word list with select
- blocks and each_with_index
- a guess loop with a win condition
- clean feedback with map and join

How the lessons actually work
Every lesson has you predict what a piece of Ruby code will output before you run it, then run it for real in your browser and fix what you got wrong. Each module ends in a challenge gate with hidden tests, so you can't advance until your code actually works. The course closes with a capstone that assembles everything into Wordle, and a runnable proof page tied to your own code.
