Math Trick Beats Wordle in 99% of Games

Researchers at Binghamton University found a math strategy that solves 99% of Wordle puzzles. They used information theory to develop a method that chooses words to reveal the most useful information.

Millions of people play Wordle every day, trying to solve its five-letter puzzle before running out of guesses. Researchers at Binghamton University in New York have found a way to dramatically improve your chances of winning.

The team used mathematics called information theory to develop a strategy that solved 99% of Wordle puzzles in simulations. The key is not to guess the answer as quickly as possible, but to choose words that reveal the most useful information.

Wordle works by giving players six attempts to identify a hidden five-letter word. After each attempt, the game shows how close you are with colors. You use these clues to narrow down your possibilities and make the next guess. The process of reducing possible answers makes Wordle a natural problem for information theory.

The research team focused on a concept called Shannon entropy, which measures uncertainty. In simple terms, it helps determine how much useful information a particular choice is expected to reveal. They used this idea to develop a strategy that chooses words to eliminate the greatest number of possibilities.

Imagine you're at a certain guess and previous guesses have eliminated many options. A word that seems unlikely to be the final answer can still be valuable if its letters help divide remaining possibilities into smaller groups. The goal is not necessarily to solve the puzzle immediately, but to make each guess reveal enough information to make the next decision easier.

The researchers compared their approach with a more conventional strategy centered on frequently used letters (like 'A', 'E', and 'R'). The difference was substantial: in simulations, the information theory method successfully solved 99% of Wordle puzzles.
