Which 6-letter words with F third and L fourth score most?

EFFLUX and AFFLUX tie at 19 points apiece. BIFLEX scores 18, DEFLEX scores 17, and INFLUX, REFLEX, and REFLUX each score 16. Those high values make the X-ending group worth checking when your rack has a premium letter.

The pattern also has words that read more naturally in everyday play: RIFLES, RIFLED, REFLEX, INFLOW, and REFLOW. The unusual entries matter for tournament word games, but the full set is not a list of familiar vocabulary. Check your game's word list before relying on a less familiar option.

How can the first and last letters narrow the pattern?

Start with R when you have a choice: 10 matches begin with that letter, including RIFLES, RIFLED, REFLEX, REFLUX, REFLOW, and RIFLER. The next-largest starting group is B, with four words. That imbalance makes an R-first guess more productive than treating every initial as equally likely.

For the final tile, test X first, then W. The seven X endings include EFFLUX, AFFLUX, BIFLEX, DEFLEX, INFLUX, REFLEX, and REFLUX; INFLOW and REFLOW show the W-ending shape. Only three matches rank among the most common English words, so use the pattern mainly for word games and crossword clues.
