🔤 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 SO__ Words in Word Puzzles
There are 129 valid five-letter words starting with SO in our dictionary. 12 of these are common, everyday words that regularly appear in curated daily puzzles like Word Equation. The remaining 117 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 SO 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 SO__ words in a single guess.
