Wordle Solver

What the Wordle Solver does

Short answer: colour your guesses above and the solver lists every word that can still be the answer, then names the next guess that narrows the field fastest. It is a filter plus a recommender. The filter drops every word your clues rule out the moment you change a tile. The recommender scores what survives and ranks the guesses most likely to finish the puzzle quickly.

By default the solver searches a curated list of 1,352 answer-quality words, the same style of list the game itself draws answers from, so results are not buried under obscure dictionary entries. One tap on the extended toggle switches to all 15,783 valid five-letter guesses when you need the long tail. Everything runs in your browser.

How it works

The solver reads each confirmed row and converts the colours into hard constraints. A green pins its letter to that exact position. A yellow says the letter is in the word but not in that spot. A grey removes the letter from every position, unless the same letter is also marked green or yellow somewhere, the duplicate-letter case most solvers get wrong.

Duplicates get exact treatment. Within a row, the green and yellow copies of a letter set a minimum count for that letter, and the solver keeps the strictest minimum across all your rows. If the same row also shows that letter in grey, the minimum becomes an exact count. One green E beside one grey E means exactly one E, so words with two are dropped.

Every word in the active dictionary is tested against those constraints. Survivors are ranked by a letter-frequency score with a bonus for distinct letters, so plausible, information-rich words rise to the top of the list.

The best-next-guess panel goes further. Once the field is down to 400candidates or fewer, the solver simulates every remaining word as a guess against every other, using Wordle’s own feedback rules, greens matched first and yellows drawn from what is left. Each simulated guess sorts the candidates into buckets, one per colour pattern, and is scored by the Shannon entropy of that split, in bits. High entropy means small, even buckets, so few candidates survive whatever feedback you get. The top three appear with their bit scores, ties broken by letter frequency, and every suggestion is itself a possible answer, so it is always hard-mode legal. The theory is unpacked on our Wordle entropy page.

Worked example

Suppose the hidden answer is CRONE and you open with SLATE. Type it, press Enter to confirm the row, then click the final tile until it turns green. The other four stay grey.

The solver now keeps only words that end in E and contain none of S, L, A or T, ranked with the most useful candidates first. A good follow-up probes fresh letters while respecting the clues, so play PRIDE. Against CRONE it scores a green R and a green E, and rules out P, I and D.

The field collapses to a handful of words with R second and E last that avoid all seven eliminated letters, such as BROKE, FROZE, GROVE and CRONE. The suggestion panel now appears, scoring each survivor in bits by how evenly it splits the rest. Tap one to drop it into the grid. The puzzle falls on row three.

Strategy tips

The solver rewards the same habits that win unassisted games.

• Fix your opener. Our entropy ranking puts TARES top at 6.22 bits, cutting the 1,352 possible answers to about 28 on average. The full ranking is on the best Wordle starting words page.
• Mark the greys honestly. A grey tile often eliminates more words than a green confirms, and the solver can only use what you mark.
• Respect duplicates. 31.7% of answers repeat a letter. Our duplicate-letter research shows which repeats appear most.
• Reach for common letters. E is the most common letter in the answer set, and the letter-frequency tables show what to test next, position by position.
• Trust the bits. When two or three candidates remain, the top suggestion splits them most evenly, which is the best you can do without luck.
• Stay curated until you cannot. Switch to the extended dictionary only for variants or missing words, because most of its extra entries will never be a daily answer.
