What is a word unscrambler?
A word unscrambler is a tool that takes a jumbled set of letters and returns every valid word those letters can spell. It differs from an anagram solver, which only returns words using all the letters, and from a word finder, which searches by pattern or position rather than by an unordered set of tiles.
In more detail
Unscramblers work by indexing a dictionary under a sorted-letter fingerprint. Because every anagram of a word shares that fingerprint, finding matches becomes a direct lookup rather than a search through possible arrangements.
The practical distinction between the three tools is what constraint you are working under. A jumbled set of tiles calls for an unscrambler. A puzzle demanding all the letters calls for an anagram solver. A grid with some squares filled calls for a pattern-based word finder.
