Letter Boxed arranges 12 letters across the 4 sides of a square. This tool finds the shortest chain of real words that uses every one of those 12 letters, where each word's last letter must start the next, and no word can use two letters from the same side back to back.
Reading your puzzle into the boxes
Enter each side's 3 letters into its own box, in any order, top side first is a reasonable default but the order between sides doesn't actually matter to the solver.
Why the shortest answer isn't the only answer
Most Letter Boxed puzzles can be solved several different ways. This tool specifically searches for the fewest possible words, checking whether a 1 or 2 word solution exists before ever considering a longer chain, since that's usually the more satisfying answer, but any valid chain that legally covers all 12 letters counts as solved.
Common mistakes when entering your box
The most frequent one is mixing up which letters belong to which side, since the same-side rule is what makes a word invalid or valid, a misplaced letter can silently reject the correct solution. The second is entering a repeated letter across two sides, a real Letter Boxed puzzle always uses exactly 12 distinct letters, one repeat means something was mistyped.

What is Letter Boxed?
A word puzzle where 12 letters sit on the 4 sides of a square, 3 per side. You form words by connecting letters, and the last letter of one word becomes the first letter of the next, trying to use all 12 letters in as few words as possible.
What's the rule about which letters I can connect?
You can connect any two letters except two on the same side of the square back to back. A word can't use two consecutive letters from the same side.
How does word chaining work?
Each new word has to start with the exact letter the previous word ended on. LEMON ending in N could be followed by NIGHT, for example.
How does this solver find its answer?
It first finds every real word your 12 letters can legally form, respecting the same-side rule, then searches for the shortest chain of those words that together uses all 12 letters, checking 2-word solutions before ever trying 3 or more.
Is the answer this tool gives the only correct one?
No, most Letter Boxed puzzles have many valid solutions. This tool returns the shortest one it can find, but plenty of other correct answers usually exist too.
Why does my puzzle sometimes have no solution here?
Either the exact 12 letters weren't entered correctly (check for typos or a repeated letter), or the true solution uses a word outside this site's dictionary.
Is this tool free?
Yes, completely free, with no account or download required.
Is this affiliated with the New York Times or Letter Boxed?
No, this is an independent, unaffiliated helper tool.
Can two consecutive letters in a word be on the same side?
No, that's the one hard rule this solver enforces, any two letters back to back in a word must come from different sides of the square.
Does the order I type each side's letters matter?
No, enter each side's three letters in any order, the solver treats them as an unordered set.
What if my puzzle has fewer or more than 12 total letters?
A standard Letter Boxed puzzle always uses exactly 12 distinct letters across its 4 sides. If your entry doesn't total 12 unique letters, double check for a typo or an accidental repeat.
Can a solution reuse the same word twice?
No, each word in a valid chain has to be a distinct dictionary word from the others.
Does this work for Letter Boxed variants with more or fewer sides?
This solver is built specifically for the standard 4 sides of 3 letters format. A different layout would need different logic.
Is my puzzle data stored or sent anywhere?
No, everything runs locally in your browser and nothing is sent to a server.
Why does the solver take a moment to return an answer?
It's searching for the shortest possible chain first before accepting a longer one, which takes a little more computation than simply returning the first working answer it finds.
