How to Use A2Z Word Finder to Unscramble Letters and Fit Words on a Scrabble Board

A2Z Word Finder takes two separate inputs: your rack letters in the Letters to Unscramble box, and any letters already on the board in the Letters to Fit Onto box. Type your tiles, use # or - for blank tiles and ? for open board squares, then click Submit to see matching words. The tool works for Scrabble, Words with Friends, crossword-style play, and several other word games, and it supports 11 languages.

Step 1: Enter your rack letters

Type the letters currently on your rack into the first Letters box.

• Use # or - to represent a blank tile. Both symbols work the same way.
• The Add # button inserts a blank-tile symbol for you, and Clear wipes the box.
• Example: if your rack is C, A, T plus one blank, enter cat#.

The unscrambler returns every word your letters can form, sorted by the option you pick in Search Options.

Step 2: Fit words onto the board

The second box, Letters to Fit Onto, handles interlocking play — words that connect to tiles already on the board.

• Enter the letters already played, and use ? (or _) for each open, playable square.
• Example: a?k matches a word where a and k are fixed and any single letter fills the gap — useful when your word must bridge two vertical words separated by one open cell.
• Set Fit pattern at to Start, Any, End, or Exact to control where the pattern must appear in the result.

The finder then unscrambles words using your rack letters plus the board letters, so results are playable on the current board rather than just valid words.

Worked example

Say the board shows c and t with one open square between them (c?t), and your rack is A, S, E.

1. Enter ase in the rack box.
2. Enter c?t in the fit box and set the pattern position to Exact.
3. Submit. The tool returns words that use your tiles and complete the c_t pattern, such as cast.

Step 3: Set Search Options

Click Search Options to open advanced settings before you submit.

Letter scores shown in results follow the game type you select, so pick the right one before judging which word scores best.

Step 4: Use Capital Letters Required as a filter

This option forces every returned word to contain specific letters — handy when you need to hit a score multiplier or fit across parallel words.

• Turn it On, then capitalize the letters that must appear.
• Cats returns only words containing c somewhere.
• Cats (with only C capitalized) would return acts, cast, cats, and scat but not sat or as.
• CaTs filters further, dropping as, at, and sat.

Use this together with the fit pattern when you need a high-value letter placed on a double- or triple-word square.

Common snags

• Blank tiles: if you type a literal # count wrong, results will include words you can't actually play. Double-check the number of blanks on your rack.
• Pattern position: leaving Fit pattern at on the wrong setting is the most common reason a valid word doesn't appear. If a?k returns nothing useful, try switching between Start, Any, and End.
• Wrong dictionary: a word valid in Scrabble-US may be rejected in Scrabble-UK or Words with Friends. Match the dictionary to your game before trusting the list.
• Mobile input: the help notes warn to be careful on phones, since tapping small cells can shift your pattern. Re-read the fit box before submitting.

What else the site offers

Beyond the main finder, A2Z Word Finder links to word lists browsable by language (French, German, Italian, Portuguese, Romanian, Spanish, Dutch, Norwegian, Swedish, Danish, and English) and to external word and language references. The site describes itself as a free educational word-game toolkit; a separate Join page exists for an upgrade, so treat any premium features as a paid option rather than assuming everything is free.
