Click any numbered cell to select it. Type the letter you think that number represents — it fills in every cell with that number across the whole grid. Use the decoder strip at the bottom to see your current code assignments. Numbers in yellow are starter letters — already revealed for you. Use Check to verify your progress, Clear Wrong to remove incorrect guesses, and Hint to reveal one unknown code.
A codeword is a crossword where every letter has been replaced by a number from 1 to 26. Your task: figure out which number represents which letter. Every codeword uses all 26 letters of the alphabet at least once. A few letters are revealed as starter clues — use logic and word-pattern recognition to decode the rest.
Codewords are uniquely satisfying because every letter you decode instantly fills in all other cells with the same number. Solving one code triggers a cascade of reveals — the board fills up rapidly as you crack more letters.
Classic, Mini (smaller grid, faster solve), Mega (larger grid, longer session), and Themed (limited letter range). Mirror Mode reverses the number-to-letter mapping for a fresh challenge. Speed Decode automatically reveals one letter every 20 seconds — a race to beat the auto-solver.
