Wordle Solver and Helper

Stuck on today's Wordle? Type the guesses you have made and the colours you got, and this helper lists every word that still fits and suggests a next guess that should narrow things down the most. You can also enter known green, yellow and grey letters directly, or check whether a word you have in mind breaks any clue. It works entirely in your browser and never looks up the day's answer.

How to use this tool

1. Type each guess and its colours on its own line, for example "crane bybbg" (g green, y yellow, b grey).
2. Or fill in the green letters by position, the yellow letters with the positions they were in, and the grey letters.
3. Tick hard mode if your next guess must use every clue.
4. Read the remaining possible answers and the suggested next guess; type a word in "Check a word" to test it.

Formula

Information of a guess = −Σ p(pattern) × log₂ p(pattern), over the colour patterns it would produce

Each candidate word is scored against every guess with Wordle's own rules: greens first, then yellows only for letters the answer still has left, so repeated letters are handled exactly. The suggested guess is the one whose possible colour patterns split the remaining words most evenly (the highest expected information in bits), checked among the most promising words; with many possibilities left, an even sample of up to 300 of them is used so the page stays fast. Possible answers are ranked by how common their letters are among the other possibilities.

Example

Suppose the answer is ABIDE and you guess SPEED. Wordle shows grey S, grey P, yellow for the first E, grey for the second E (the answer has only one), and yellow D: "bbyby". Entering that line keeps ABIDE among the possibilities, and "Check a word" confirms it fits. With "crane bbbgg" followed by "stone ggggg", only STONE remains.
