Letter Boxed Solver: One- and Two-Word Solutions

Letter Boxed Solver

This Letter Boxed solver takes the twelve letters around the square, three on each side, and finds every word that follows the puzzle's rules. It then looks for short solutions that use all twelve letters in one word or a chain of two.

Enter the three letters on each side of the box, then press Solve.

How do you solve Letter Boxed in two words?

Find two words that together use all twelve letters, where the second word starts with the last letter of the first. The solver tests every valid pair for your box and lists the shortest pairs first, along with any single word that uses every letter. If no pair exists in its word list, the list of valid words still helps you build a longer chain.

How to use the Letter Boxed helper

Type the three letters of each side into its box: top, right, bottom and left. The order inside a side does not matter.
Check that all twelve letters are different, then press Solve. The first solve downloads the word list once.
Read the one-word and two-word solutions at the top. Below them, every valid word is grouped by how many of the twelve letters it covers, which is useful if you want to find your own chain.

How to play Letter Boxed

Twelve letters sit around a square, three per side. You spell words by moving from letter to letter, with three rules:

Every word is at least 3 letters long.
Two letters in a row cannot come from the same side, so a word keeps bouncing across the box.
Each new word starts with the last letter of the previous word.

Letters can be used more than once. You win when every one of the twelve letters has been used, and the challenge is to do it in as few words as possible. Two words is an excellent result; one word is rare.

How the solver works

The letter boxed word finder walks through the dictionary and checks each word letter by letter: is the letter in the box, and is it on a different side from the letter before it? Words that pass are valid moves. For each valid word the solver also records which of the twelve letters it uses, as a compact set.

To find two-word solutions, it groups the valid words by their first letter. For each word, it only needs to look at the group that starts with that word's last letter and keep the partners whose letters, combined with its own, cover all twelve. The results are sorted by total length, so short, tidy solutions come first. Everything runs in your browser and usually finishes in a few hundredths of a second.

Example

For a box with the sides BRU / OYL / CIN / TEA, the solver finds 995 valid words and 58 two-word solutions. The shortest is BILAYER then RECOUNT, fourteen letters in all, followed by CORNUAL then LIBERTY. A word like BRACE is not allowed in this box because B and R share the top side.

About the word list

The solver uses the public-domain ENABLE word list, with slurs and the strongest profanity removed. The puzzle itself uses a different list, so a solution found here might be rejected, or the game might accept a word this list lacks. If a pair does not work, try the next one. For letter puzzles without the side rule, the Spelling Bee solver finds words from a set of seven letters.

Frequently asked questions

How to play Letter Boxed?

Use all twelve letters around the square by spelling a chain of words. Each word needs at least three letters, two letters in a row must come from different sides of the box, and each new word starts with the last letter of the word before it; the aim is to use every letter in as few words as you can.

How does the solver find two-word solutions?

It collects every valid word for your box, pairs each one with the words that start with its last letter, and keeps the pairs whose letters together cover all twelve. The pairs are sorted by total length, so the shortest two-word solutions appear first.

Can consecutive letters come from the same side?

No. Two letters that sit next to each other in a word must come from different sides, which also rules out double letters such as the LL in BALL. Letters from the same side can still appear in one word as long as a letter from another side comes between them.
