The solver uses pattern matching with ? or _ as wildcards representing exactly one unknown letter. For example, c?t matches all 3-letter words starting with 'c' and ending with 't' (like cat, cot, cut). The tool searches through a comprehensive dictionary of thousands of English words to find all matches. You can also filter by required letters (Must Contain) and excluded letters for more precise results.

Currently supported wildcards: ? and _ — both represent exactly one unknown letter. The pattern s???r matches any 5-letter word starting with 's' and ending with 'r'. The Must Contain field accepts comma-separated letters that must appear in the word (any position). The Exclude field lets you specify letters that should NOT appear. Length filters allow you to narrow results to a specific word length range.

The built-in dictionary contains over 5,000 commonly used English words, ranging from 2 to 15 letters in length. This includes frequently used crossword puzzle vocabulary, common nouns, verbs, adjectives, and many word game staples. The dictionary is curated to provide high-quality matches for most crossword and word game scenarios. All words are stored in lowercase for case-insensitive matching.

No, all searches are case-insensitive. You can enter patterns in uppercase, lowercase, or mixed case — the tool will automatically normalize everything to lowercase for matching. This makes it easier to quickly type patterns without worrying about capitalization.
