Our tool loads a curated English dictionary (10,000+ common words). It first finds all valid words that can be formed from the given letters while respecting the "no consecutive same-side letters" rule. Then it uses a depth-first search to discover the shortest possible word chains that cover every letter exactly once. Results are sorted by the number of words (fewer is better).

The default dictionary includes the most common English words (length ≥ 3), fetched from a trusted open-source word list. You can also paste your own custom word list (one word per line) using the advanced option that appears when you need more control.

The NYT puzzle uses a larger dictionary that may include obscure words, proper nouns, or compound words. Our default dictionary is limited to the most frequent English words to ensure fast performance. If a solution requires a rare word, try pasting an extended word list or use the puzzle's official answer.

Yes! Click the "Use custom dictionary" button (appears after the default dictionary loads). You can paste a list of words (one per line) and the solver will use that instead. This is perfect if you have a specialized vocabulary or want to restrict to certain word lengths.

That’s the core rule of Letter Boxed. It forces you to jump from side to side, which dramatically reduces the number of possible words and makes the puzzle challenging. It also creates interesting patterns where the first and last letters of words often determine the chain.
