Wordle is a popular online word guessing game. To win, you should guess the word in six tries. Each guess must be a valid five-letter word. After each guess, the color of the tiles will change to show how close your guess was to the word. green means the letter is in the word and in the correct spot. yellow means the letter is in the word but in the wrong spot. grey means the letter is not in the word in any spot.
This powerful worlde-solver is written in python, run on terminal. Inspired by 3Blue1Brown's work, I use maxmum entropy to generate the next guess. It can help you win with least attempts statistically. And, assuming all target words share the same chance, I do not use word frequency to reweight them. In 2315/2315 words mode, the winning rate is 100%.
