Researchers find a Wordle strategy that wins 99% of the time
Researchers at Binghamton University have used information theory and Shannon entropy to identify a Wordle strategy that wins 99% of the time. The method prioritizes guesses that maximize the elimination of incorrect possibilities rather than guessing the word immediately.
Why it matters
This demonstrates the practical application of mathematical information theory to solve everyday puzzles and optimize decision-making processes.
Millions of people open Wordle each day hoping to solve its five-letter puzzle before their six guesses run out. Now, researchers at Binghamton University, State University of New York, say mathematics can dramatically improve the odds.
By applying information theory, the team developed a strategy that solved 99% of Wordle puzzles in simulations. The key is surprisingly counterintuitive. Instead of always trying to guess the answer as quickly as possible, the method favors words that reveal the greatest amount of useful information.
Wordle gives players six attempts to identify a hidden five-letter word. The game begins with no clues, so the first guess can be any valid word.
After each attempt, Wordle uses colors to show how close the player is:
