How is this different from the word unscrambler?

The unscrambler returns every word your letters can make, including short ones that use only a few. This returns only words that use all of them, which is what "anagram" strictly means. Same engine, one filter.

Why does my rack have no anagrams?

Most random letter sets have none. English has roughly 3,200 seven-letter words in the Tournament dictionary against 65 million possible seven-letter strings, so a rack that spells nothing in full is the normal case rather than a bug. Try the unscrambler for the longest partial words instead.

Can I use a blank tile?

Yes. A ? stands for any letter and still has to be spent, so a six-letter rack with one blank returns seven-letter anagrams.

Anagram Solver

A true anagram uses every letter you have, once each. Enter your letters and this returns only the words that spend all of them — no shorter words padding the list.

What counts as an anagram

An anagram spends every letter exactly once. LISTEN and SILENT are anagrams; LISTEN and LINES are not, because LINES leaves a T unused. That distinction is the whole difference between this page and the unscrambler, which happily returns the shorter word.

The search runs the same way either tool asks it. Your letters are sorted into a key — RETINAS and NASTIER both become AEINRST — and that key is looked up in an index built the same way. Every word filed under it is an anagram of your rack, which is why the answer arrives in well under a millisecond rather than by trying arrangements one at a time.

Why most racks have none

There are 26⁷ — about eight billion — seven-letter strings, and the Tournament dictionary contains roughly 23,000 seven-letter words. A random rack spelling a full anagram is the exception, not the rule, so an empty result here usually means the letters genuinely make nothing rather than that something went wrong.

Vowel balance is what usually decides it. Racks of about two vowels to three consonants have the best odds; five consonants and a Q with no U is close to hopeless. AEINRST is the famous exception — the seven most useful letters in English, which between them make more seven and eight-letter words than any other combination.

Blanks and longer racks

A blank tile widens the search without changing what an anagram is: it still has to be spent, so six letters and one blank produce seven-letter results. Two blanks are allowed, matching a Scrabble set. Because a blank can stand for any of 26 letters, the number of keys to check rises sharply, and the solver switches to walking the dictionary and testing each word for fit — the faster route once blanks are involved.

Above about eleven letters, full anagrams get scarce again for the opposite reason: there simply are not many long words, and they have very particular letter patterns. If you are working on a long rack, the unscrambler will show the longest word that fits even when nothing uses every tile.
