About this word list
With only 9 matches in our dictionary, every word here is worth memorising — there are no filler entries. If you struggle with vowel-heavy racks, note that 6 of these words contain mostly vowels and hook cleanly onto existing board words. Watch for recurring suffixes like -CS, -DE, -DO, -OCS when planning hooks and parallel plays. The highest-scoring word shown is iowa at 7 points. Wordle players can use this list to build a mental model of valid pattern words before guessing — especially when narrowing by known greens and yellows. Words with Friends shares most of these entries; the average score of 5.1 points reflects standard tile values without board multipliers. With a vowel ratio of 0.67, this list favours vowel-rich racks.

Strategy & study tips
A compact result set means you can memorise the entire page in one session. Treat each word as high leverage — there is little noise to filter out.
When the board already shows the first letters, this page validates every 4-letter continuation before you spend a turn. Internal links point to Pattern Finder, Crossword Solver, Anagram Solver, and Wordle Solver — each tool adds interactivity this static list intentionally omits. Anchor words: highest scorer IOWA, longest IOWA. Build mnemonics around those two before expanding into the full 9 matches.
