How to Play Letter Boxed-Style Puzzles
LetterBorder is a word puzzle game where you connect letters to form words and solve the daily challenge. Here's everything you need to know.
The Basics
You'll see 12 letters arranged on 4 sides of a square, with 3 letters per side:
Example layout (letters vary daily)
The Rules
1. Form Valid Words
Create words using the available letters. Words must be at least 3 letters long and found in the dictionary.
2. No Consecutive Letters from the Same Side
You cannot use two letters in a row from the same side of the square. Each letter must come from a different side than the previous one.
Example: If "A" and "B" are on the same side, you can't use them consecutively in a word.
3. Chain Your Words
The last letter of one word must be the first letter of the next word.
CAT → TABLE → ELK
4. Use All 12 Letters
Your goal is to use every letter at least once across all your words. Once you've used all 12 letters, you've solved the puzzle!
Scoring & Par
Every puzzle has a Par score - the target number of words needed to solve it efficiently.
- Beat Par: Solve the puzzle in fewer words than par
- Meet Par: Solve it in exactly par words
- Above Par: Solve it, but with more words than par
Challenge yourself to beat par and improve your word puzzle skills!
Tips & Strategies
- Look for long words first: Longer words use more letters, getting you closer to the solution faster.
- Pay attention to difficult letters: Letters like Q, X, or Z can be challenging - plan words around them early.
- Think about word endings: Consider what letters you'll end on to ensure you can chain the next word.
- Use the practice mode: Build your skills with unlimited practice puzzles.
- Track which letters you've used: The game highlights used letters to help you track your progress.

Worked Example: Solving a Board Step-by-Step
Walk through a real solve to see how the rules play out in practice. Say you get this board:
Top: R O T | Right: H I D | Bottom: E N G | Left: F L K
Step 1 — Identify the hard letters
Scan for uncommon letters first: K and F are the toughest to place. You don't want to find yourself with only these two left and no valid word. Plan around them up front.
Step 2 — Find a long first word that hits a hard letter
Try FLINCHED: F(left), L(left) — same side, rejected. Try FLINTED: F(left), L(left) — same side again. The side constraint bites quickly.
Try FRONTIER: F(left), R(top), O(top) — same side, rejected at O. The game rejects the moment two consecutive letters share a side.
Try FRIGHT: F(left), R(top), I(right), G(bottom), H(right), T(top) — every consecutive pair is on a different side. Valid! Six letters covered in one word: F, R, I, G, H, T.
Step 3 — Chain from the last letter
FRIGHT ends in T. Your next word must start with T. You still need: O, L, K, E, N, D.
Try TOKEN: T(top), O(top) — same side, rejected. Try TONED: T(top), O(top) — same side. Try LODEN: starts with L, not T. Wrong chain letter.
Try TOLKIEN — it's a proper noun, not valid. Keep scanning.
Try DONKEY: starts with D, not T. Try thinking of T words that use O, L, K, E, N, D from different sides. How about ELK: E(bottom), L(left), K(left) — same side rejected at K. Try LEND: starts with L, not T.
Step 4 — Coverage tracking and the two-word solve
This is where the game's letter highlighting helps. As you type, letters turn green on the board when they're covered. At a glance you can see the gap.
Back to our T chain: try KNOLED — not a word. Try DONGLE: starts with D. What if we had ended FRIGHT differently? That's the real lesson — sometimes the right move is to reset the first word so the second word becomes cleaner.
After resetting: first word GRONED (not real) — the point is, keep scanning. When you find a two-word solution that covers all 12 letters, that's a par or better solve. Two words beats par on most boards. The green highlight flood is deeply satisfying.
Advanced Strategy
Once you're comfortable with the rules, these techniques will push your solves from par toward two-word mastery.
Bridge Letters: End on Good Starting Letters
The letter you end a word on becomes the letter you must start the next word with. This makes your word ending one of the most important choices in the game.
Ending on high-frequency starting letters — S, T, R, E, A, D — gives you the most options for word two. Ending on J, X, Q, Z, K tends to paint you into a corner because few words begin with those letters.
Ending on a vowel is often especially powerful. An enormous number of English words start with A, E, I, O, or U. If you can end word one on E, word two has huge range — ELSE, ENTER, ERODE, ENLIST, and hundreds more. Mentally catalog your vowel-starting options before committing to a word ending.
Coverage-First Approach: New Letters per Word
Instinct says "longer words are better." That's only half true. What you actually want is more new letters per word — letters you haven't covered yet.
An 8-letter word that re-uses 5 letters you've already covered only adds 3 new ones. A 5-letter word that hits 5 brand-new letters is twice as efficient. When you're scanning for word two, don't just look for a long word — look for a word that sweeps up the remaining uncovered letters.
A useful habit: before typing, mentally list which letters are still dark (uncovered). Now look for a word that contains as many of those dark letters as possible, in any order, from different sides.
Handling Difficult Letters: Q, X, Z, K, J
Rare letters are the bottleneck in almost every hard board. The instinct is to deal with them last — resist it. Build your first word around the hard letter instead.
Common patterns to keep in your mental toolbox:
- Q: Almost always needs U — but Q and U must be on different sides. Words like QUILT, QUEST, QUOTE work when Q and U are separated. If they share a side, you need QI or QOPH (valid Scrabble words).
- X: Look for EX- prefix words (EXACT, EXILE, EXIST) or -AX suffix (RELAX, FLAX, HOAX). X as a word-ender is dangerous — few common words start with X for your chain.
- Z: -ZING endings (BLAZING, GLAZING, HAZING) or ZA (valid Scrabble, means pizza). ZERO, ZONE, ZEAL all work as starters.
- K: Strongest as a word-middle letter. KNIGHT, KNACK, STROKE, FLAKE. K as a word-ender gives you fewer chain options.
- J: JAB, JAR, JOT, JIG, JOIN — J is almost always a word-starter. If J is mid-board, look for -JUST or ADJUST patterns.
The takeaway: whatever your rarest letter is, make covering it your first constraint, not your last.
Side-Switching Rhythm
Think of the four sides as positions in a rhythm: Top-Right-Bottom-Left-Top-Right... Any pattern that never repeats consecutive sides is valid. Once you internalize this as a rhythm rather than a rule, you start to feel valid paths instead of calculating them.
A useful drill: pick any 4-letter combination and tap out a rhythm on the board — Top, Right, Bottom, Left. That sequence always satisfies the constraint. Then see if any real word uses letters in those exact positions. This is how players spot long valid words surprisingly fast.
When to Reset and Start Over
Sometimes word one looks great, and then word two simply doesn't exist. Maybe you ended on X. Maybe the 6 remaining letters don't form a single valid word regardless of start letter.
The instinct is to push through — try every possible word starting with that ending letter. That's usually the wrong call. Experienced players recognize a dead end within 30 seconds and immediately clear the board to try a different first word. The board is always the same; your approach to it isn't. Clearing and resetting costs nothing. Forcing a bad chain costs minutes.
Difficulty Levels & Progression
Not every board is created equal. LetterBorder boards span a range of difficulty based on the letters present and how many valid word chains exist.
Common letters (A, E, R, S, T, N), many valid long words, lots of possible chains. Par is typically 4–5 words. Great for warming up or building confidence.
A mix of common and less-common letters. Two-word solutions exist but require deliberate strategy. Par is typically 3–4 words.
Rare letters (Q, X, Z), a narrow vocabulary of valid words, and a two-word solve that takes real effort to find. Par is typically 2–3 words. These boards are genuinely hard and intentionally so.
The daily puzzle varies in difficulty — some days are designed to be tougher than others. If you want to train on easier boards before tackling a hard daily puzzle, try Practice Mode, which generates boards across all difficulty levels so you can build skills at your own pace.

Frequently Asked Questions
What are the rules of Letter Boxed-style puzzles?
Form words using letters on 4 sides of a square. You cannot use two consecutive letters from the same side. Chain words so the last letter of one word starts the next. Cover all 12 letters to solve the puzzle.
How does par scoring work?
Each puzzle has a par number (for example, par 4). Solving in fewer words beats par. The par is calculated when the board is generated based on how many valid efficient word chains exist.
Can I practice without affecting my streak?
Yes. Practice Mode generates unlimited boards that do not count toward or against your daily streak. Use it to warm up or improve your skills before attempting the daily puzzle.
Why was my word rejected?
A word can be rejected for several reasons: it is not found in the TWL Scrabble dictionary, two consecutive letters come from the same side of the board, the word does not chain correctly (the first letter must match the last letter of your previous word), or the word is fewer than 3 letters. Check each of these before trying again.
What counts as a valid word?
Any word that is 3 or more letters long and found in the TWL Scrabble dictionary is valid, excluding profanity. Proper nouns (names, places, brands) and abbreviations are not accepted. If a word is in a standard dictionary but not TWL, it may be rejected — TWL is the authoritative source.
What is the difference between LetterBorder and NYT Letter Boxed?
Both use the same core mechanic: 12 letters on 4 sides, word chaining, cover all letters to win. LetterBorder adds free unlimited practice, a full puzzle archive, and a par scoring system. No subscription or login is required to play LetterBorder.
