Using RU__ Words in Word Puzzles

There are 65 valid five-letter words starting with RU in our dictionary. 8 of these are common, everyday words that regularly appear in curated daily puzzles like Word Equation. The remaining 57 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 RU 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 RU__ words in a single guess.
