About this word list
With 168 valid entries, this is one of the larger curated lists on unscrambletools.com, sorted by length and Scrabble score for quick scanning. Among these entries, 23 contain rare tiles that can dramatically boost your score when played on double- or triple-letter squares. Common endings in this list include -US, -SS, -AL, -ESS — patterns that let you extend words already on the board. For quick wins, prioritise belshazzaresque (47 pts) — they lead this list on raw tile value. While Wordle uses a smaller answer list, studying broader dictionary patterns here helps you eliminate impossible guesses faster. In tournament Scrabble, knowing word counts and score distributions for common patterns saves seconds per turn — seconds that add up over 30+ games. With a vowel ratio of 0.39, this list skews consonant-heavy — keep extra vowels on your rack when targeting these words.

Strategy & study tips
Premium letters drive the top of this list. Prioritise words with Q, X, Z, J, or K when double- and triple-letter squares are open — raw tile value here often exceeds 15 points before multipliers. About 14% of sampled words include a high-value letter (Q, X, Z, J, or K) — useful when planning premium-square plays.
When the board already shows the first letters, this page validates every 15-letter continuation before you spend a turn. Average Scrabble value here is 26.3 points — use that as a floor for acceptable plays when board space is tight.
