Frequently Asked Questions
Everything you need to know about Word Fill
Word Fill shows you partially spelled words with one or more missing letters — for example C_T. Type the missing letter into the input box and press Enter or click "Submit" to check. A correct answer fills the blank and advances you to the next word; an incorrect answer gives you another chance while breaking your streak.
Word Fill has three difficulty levels: Easy (3-4 letter words with one blank), Medium (5-6 letter words with 1-2 blanks), and Hard (7-9 letter words with up to 3 missing letters). Switch anytime using the buttons above the scoreboard — each switch generates a fresh curated word list.
Every correct answer awards a base score that scales by difficulty, plus a streak multiplier for each consecutive correct guess. Using the "Hint" button deducts points and resets your streak. "Skip Word" also resets your streak so use it sparingly. Try to keep a long streak alive for the highest scores!
Yes — click the "Hint" button to reveal the definition, first letter, or a clue for the current word. Each hint costs a small number of points and resets your combo streak, so balance hints against your score goals. You can also use "Skip Word" to move on entirely.
Absolutely. Word Fill is perfect for children, spelling bee practice, homeschooling, and adult ESL / EFL learners.

💡 Word Fill Tips & Strategy
Word Fill is a crossword-style missing-letter puzzle: each grid shows partially completed words, and you type letters into the blank cells to finish them all. Every correct fill locks in, and intersecting words share letters, so a solved word instantly gives you clues for its neighbors. You can play in relaxed mode at your own pace or timed mode for a score chase, and three kinds of help are on hand - reveal a single letter, show the first letter of a word, or check your current answers. It is equally good for kids building spelling confidence and adults keeping their vocabulary sharp.
Tip 1. Start with the shortest words - two- and three-letter fills have few possibilities and often unlock the shared letters of longer intersecting words.
Tip 2. Read intersecting answers as cross-clues - a letter you confirm in one word is a guaranteed letter in every word that crosses it.
Tip 3. Watch common letter pairs and endings - TH, -ING, -ED, -ER, and -LY patterns make the missing slots obvious at a glance.
Tip 4. Spend 'reveal a letter' on long words only - the hint is most valuable where one confirmed letter collapses many candidates.
Tip 5. Warm up in relaxed mode - learning the puzzle types without a clock builds the pattern memory that makes timed mode feel easy.
