What is Wordle Solver?

Wordle Solver has two focused modes. Play gives you a clean, normal Wordle board with keyboard-first input. Solver helps with an external game by ranking legal guesses against the remaining official answer set.

The recommendation engine uses Wordle-correct duplicate-letter scoring, validates guesses against an allowed dictionary, and keeps answer candidates separate from exploratory guess words.

Key Features:

  • Play mode: normal gameplay without recommendation panels
  • Solver mode: helper panels for narrowing down external games
  • Keyboard support: type letters, use backspace, and press enter to submit
  • Theme toggle: switch between light and dark mode
How to Use

1Solver Mode

  • Left Panel: Shows all remaining possible words
  • Right Panel: Displays AI recommendations ranked by entropy
  • Ranked suggestions: Explore strong answer and probe guesses
  • Manual selection: Pick any candidate and then enter the feedback you saw

2Play Mode

  • Clean interface: focus only on the board
  • Keyboard-first: type anywhere, use backspace, press enter to submit
  • Manual input: the active row mirrors what you type
  • Fresh puzzles: start a new game at any time
The Science Behind It

The solver uses information theory, specifically entropy calculations, to rank guesses. Here's how it works:

Entropy Calculation Process:

  1. 1. Pattern analysis: each legal guess is checked against the remaining official answers
  2. 2. Wordle-correct scoring: duplicate letters use the same matching rules as the real game
  3. 3. Probability calculation: each feedback partition gets a probability based on the current answer set
  4. 4. Entropy ranking: higher entropy means a guess is expected to eliminate more answers

The highest-entropy guess is the one expected to cut down the answer space the most on average, even when that guess is not itself a remaining answer candidate.
