Codeword puzzles to keep you busy during coffee break. This full version has 900 complete puzzles. Codewords are crossword puzzles with a twist - there are no clues. Instead, each letter A-Z is represented by a random number 1-26, with the same number representing the same letter throughout the puzzle. All you have to do is decide which letter is represented by which number. For example, all the 1's may be T's, all the 2's E's and so on. You are given some letters to help start off. All the letters A-Z are present in the early puzzles, with one number for each letter (later puzzles don't necessarily have all 26 letters in the grid). The codewords grid is displayed in full. If you are really stuck then you can reveal a letter. A great way to while away your commute! Features: - zooming grid - cheats and answer checking - landscape mode Also known as Enigma Code, Code Breaker, Cipher crosswords, Code Crackers and Kaidoku. If you're after a bigger challenge, try our Crossword apps - casual, cryptic and US style versions are available.
