How to solve codeword puzzles: a beginner's method

A codeword looks impossible at first glance: a full crossword grid with no clues whatsoever. It's actually one of the most systematic puzzles there is.

6 min read

In a codeword, every square holds a number from 1 to 26, and each number consistently represents the same letter across the entire grid. You get two or three letters to start. That's all the information there is — and it's genuinely enough.

Start with frequency, not guessing

Count how often each number appears. In English, E is by far the most common letter, followed by T, A, O, I and N. The number appearing most often in your grid is very likely E. That single deduction usually unlocks several words at once, because E is also extremely common at the ends of words.

One-letter words are free information

If the grid contains a single-square word, it's A or I. Almost nothing else exists in English. Two-letter words are similarly constrained — OF, TO, IN, IS, IT, AT, ON, AS, BE, BY. A short word is the most information-dense square on the board.

Look for the structural giveaways

  • A three-letter word where the first and third numbers match is very likely EYE, EWE, DID, or a similar pattern.
  • A doubled number mid-word is usually LL, SS, EE, OO or TT.
  • A number appearing at the end of many different words is probably S, E, D or Y.
  • Q is always followed by U — if you spot a number that only ever precedes one specific other number, you may have found QU.

Work the tracker, not the grid

Lexora shows a letter tracker of which letters you've already assigned. Consult it constantly. Elimination does enormous work in a codeword: once fifteen letters are placed, the remaining eleven are heavily constrained, and a word that looked ambiguous becomes forced.

Why difficulty changes the puzzle

On easy, roughly 40% of the letters are revealed to start; on medium about 20%; on hard you get two. That isn't just a scaling of tedium — it changes the method. With many starters you can read partial words directly. With two, you must lean entirely on frequency analysis first.

Codewords reward patience more than vocabulary. If you can hold a hypothesis loosely and test it, you can solve them — and the moment a single letter cascades across the whole grid is genuinely one of the best feelings in puzzling.

Common questions

How do you start a codeword puzzle?
Count the numbers. The most frequent one is almost certainly E, and any single-letter word is A or I. Those two deductions alone usually open several words.
What are the most common letters in English?
In rough order: E, T, A, O, I, N, S, H, R. Frequency analysis using this order is the core codeword-solving technique.
