How to Play Codeword

Master the art of solving number-to-letter code puzzles with these proven strategies.

The Fundamental Rules

  • Bijective 1-to-26 Code: Every letter from A to Z is replaced by a unique number from 1 to 26.
  • Shared Mapping: Mapping a number to a letter updates all matching numbered cells throughout the puzzle.
  • Punctuation & Spaces: Spaces, commas, periods, and apostrophes remain unencrypted as structural clues.

Step-by-Step Solving Strategy

1

Select a numbered tile to highlight every cell sharing that same number across the board.

2

Check your pre-revealed starter numbers: Use the starter letters as your starting foothold.

3

Look for single-letter words: In English quotes, single-letter words are almost exclusively 'A' or 'I'.

4

Spot short common words: 2-3 letter words like 'THE', 'AND', 'OF', 'IN', 'TO' reveal key letters.

5

Identify apostrophe contractions: Words like 'DON'T', 'CAN'T', 'IT'S' immediately reveal 'T', 'S', and 'M'.

6
