Connect twelve letters arranged three per side on a square into a chain of words, without ever using two consecutive letters from the same side, until every letter has been used. That’s it. Everything else in this guide is about understanding why that’s harder than it sounds, and how to get really good at it.
Each of the four sides has three letters. When spelling any word, the letter you place next cannot come from the same side as the letter you just placed. This is the rule that makes Letter Boxed unique.
The last letter of your first word becomes the first letter of your second word. The last letter of your second word starts your third. The chain must be unbroken from start to finish.
No single letters, no two-letter words. Every word must be at least three characters long.
All twelve letters on the board must appear in your completed word chain at least once each. Letters can be reused freely, but none can be left out.
You win when every single letter on the board has been used at least once across all your words. Letters can be reused as many times as you like, but each one must appear in your solution at least once.
Every puzzle has a par the target number of words for a well-executed solution. Par is usually 4 to 6 words. Your score is based on how close to (or below) par you finish. A two-word solution covering all twelve letters in just two chained words is the puzzle equivalent of a perfect game. They’re rare and legitimately difficult, but achievable on many boards.
J, Q, V, X, and Z appear in far fewer English words. Always map a path through them before building the rest of your chain. Leaving them for last is the #1 mistake that forces players into extra words.
Pick the letter you want to end the puzzle on ideally a common starting letter like S, T, A, or E then plan backward. Backward planning finds two-word solutions that forward thinking misses.
Most elegant solutions follow a pattern: one long word (6–9 letters) uses most of the board, followed by a short second word that collects whatever’s left. When stuck, search for the longest possible word in your letter set first, then see what remains.
Experienced players stop thinking about individual letters and start thinking about the four sides as zones. Each move crosses a zone boundary. Mapping your word path as a sequence of zone-crossings makes the same-side rule intuitive.
