Wordle is a daily wordβguessing puzzle where a player has a limited number of attempts to discover a hidden fiveβletter word. The difficulty of the game can be quantified by the *expected number of guesses* required to solve the puzzle under a given strategy.
Different solving strategiesβsuch as entropyβmaximising, optimalβbranching, or random guessingβaffect the probability distribution of each guess. By modelling the reduction of the candidate word list after each feedback, we can estimate how many turns a player will need on average.
The expected value is derived from the probability of solving the puzzle at each turn. If (p_k) denotes the probability of solving on the (k)βth guess, the expected number of guesses (E) is
