Keywords — Codeword Puzzle

A codeword is a crossword where every letter is represented by a number. Its salient feature is the absence of clues for the words. Only one particular letter corresponds to each number in a codeword. The goal of the puzzle is to restore the original coded crossword. The game is unique in that it is a number, word, and logic puzzle all in one!
