In recent years English newspapers have started featuring a number of puzzles other than the ubiquitous crossword. Many of the puzzles are of Japanese origin such as Sudoku, Kakuro or Hidato. However, one recent one is very English and is called variously Cross-code, Alphapuzzle or some other name. In this article, it will be known as Codeword. The object of the puzzle is to substitute each small number with a letter from A to Z wherever the number occurs so that appropriate words (or rarely phrases) are formed both horizontally and vertically. The puzzle is solved using intuition together with knowledge of English words and letter patterns. In this article, the authors consider various statistical tests applied to the puzzles, hopefully to provide a slightly novel application of these tests. (Contains 3 tables and 2 figures.)
