🔤 Put These Words to the Test
Word Equation is a free daily word puzzle where your only clue is a number — how many letters are in the exact correct position. Harder than Wordle, and more satisfying to solve.
Valid in word games but less commonly known — archaic, technical, or regional English. Useful to know when stuck, but unlikely in a curated daily puzzle.
Using AU__ Words in Word Puzzles
There are 25 valid five-letter words starting with AU in our dictionary. 3 of these are common, everyday words that regularly appear in curated daily puzzles like Word Equation. The remaining 22 are valid but less familiar — useful to know when you're stuck, but unlikely to appear in a standard daily puzzle.
If you've confirmed AU at the start of a puzzle, your next move is to nail down the third letter. Try a guess that places different vowels and common consonants in position 3 to eliminate large groups at once. In Word Equation, every number you receive tells you exactly how many letters are in the right spot — use that to rule out entire clusters of AU__ words in a single guess.
